# How to use Fescar to ensure consistency between Dubbo Microservices
|
||||
## Use case
|
||||
|
||||
A business logic for user purchasing commodities. The whole business logic is powered by 3 microservices:
|
||||
|
||||
- Storage service: deduct storage count on given commodity.
|
||||
- Order service: create order according to purchase request.
|
||||
- Account service: debit the balance of user's account.
|
||||
|
||||
### Architecture
|
||||
|
||||
|
||||
|
||||
|
||||
### StorageService
|
||||
|
||||
```java
|
||||
public interface StorageService {
|
||||
|
||||
/**
|
||||
* deduct storage count
|
||||
*/
|
||||
void deduct(String commodityCode, int count);
|
||||
}
|
||||
```
|
||||
|
||||
### OrderService
|
||||
|
||||
```java
|
||||
public interface OrderService {
|
||||
|
||||
/**
|
||||
* create order
|
||||
*/
|
||||
Order create(String userId, String commodityCode, int orderCount);
|
||||
}
|
||||
```
|
||||
|
||||
### AccountService
|
||||
|
||||
```java
|
||||
public interface AccountService {
|
||||
|
||||
/**
|
||||
* debit balance of user's account
|
||||
*/
|
||||
void debit(String userId, int money);
|
||||
}
|
||||
```
|
||||
|
||||
### Main business logic
|
||||
|
||||
```java
|
||||
public class BusinessServiceImpl implements BusinessService {
|
||||
|
||||
private StorageService storageService;
|
||||
|
||||
private OrderService orderService;
|
||||
|
||||
/**
|
||||
* purchase
|
||||
*/
|
||||
public void purchase(String userId, String commodityCode, int orderCount) {
|
||||
|
||||
storageService.deduct(commodityCode, orderCount);
|
||||
|
||||
orderService.create(userId, commodityCode, orderCount);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```java
|
||||
public class StorageServiceImpl implements StorageService {
|
||||
|
||||
private StorageDAO storageDAO;
|
||||
|
||||
@Override
|
||||
public void deduct(String commodityCode, int count) {
|
||||
Storage storage = new Storage();
|
||||
storage.setCount(count);
|
||||
storage.setCommodityCode(commodityCode);
|
||||
storageDAO.update(storage);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```java
|
||||
public class OrderServiceImpl implements OrderService {
|
||||
|
||||
private OrderDAO orderDAO;
|
||||
|
||||
private AccountService accountService;
|
||||
|
||||
public Order create(String userId, String commodityCode, int orderCount) {
|
||||
|
||||
int orderMoney = calculate(commodityCode, orderCount);
|
||||
|
||||
accountService.debit(userId, orderMoney);
|
||||
|
||||
Order order = new Order();
|
||||
order.userId = userId;
|
||||
order.commodityCode = commodityCode;
|
||||
order.count = orderCount;
|
||||
order.money = orderMoney;
|
||||
|
||||
return orderDAO.insert(order);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Distributed Transaction Solution with Fescar
|
||||
|
||||
|
||||
|
||||
We just need an annotation `@GlobalTransactional` on business method:
|
||||
|
||||
```java
|
||||
|
||||
@GlobalTransactional
|
||||
public void purchase(String userId, String commodityCode, int orderCount) {
|
||||
......
|
||||
}
|
||||
```
|
||||
|
||||
## Example powered by Dubbo + Fescar
|
||||
|
||||
### Step 1: Setup database
|
||||
|
||||
- Requirement: MySQL with InnoDB engine.
|
||||
|
||||
**Note:** In fact, there should be 3 database for the 3 services in the example use case. However, we can just create one database and configure 3 data sources for simple.
|
||||
|
||||
Modify Spring XML with the database URL/username/password you just created.
|
||||
|
||||
dubbo-account-service.xml
|
||||
dubbo-order-service.xml
|
||||
dubbo-storage-service.xml
|
||||
|
||||
```xml
|
||||
<property name="url" value="jdbc:mysql://x.x.x.x:3306/xxx" />
|
||||
<property name="username" value="xxx" />
|
||||
<property name="password" value="xxx" />
|
||||
```
|
||||
### Step 2: Create UNDO_LOG table for Fescar
|
||||
|
||||
`UNDO_LOG` table is required by Fescar AT mode.
|
||||
|
||||
```sql
|
||||
CREATE TABLE `undo_log` (
|
||||
`id` bigint(20) NOT NULL AUTO_INCREMENT,
|
||||
`branch_id` bigint(20) NOT NULL,
|
||||
`xid` varchar(100) NOT NULL,
|
||||
`rollback_info` longblob NOT NULL,
|
||||
`log_status` int(11) NOT NULL,
|
||||
`log_created` datetime NOT NULL,
|
||||
`log_modified` datetime NOT NULL,
|
||||
`ext` varchar(100) DEFAULT NULL,
|
||||
PRIMARY KEY (`id`),
|
||||
KEY `idx_unionkey` (`xid`,`branch_id`)
|
||||
) ENGINE=InnoDB AUTO_INCREMENT=159 DEFAULT CHARSET=utf8
|
||||
```
|
||||
|
||||
### Step 3: Create tables for example business
|
||||
|
||||
```sql
|
||||
|
||||
DROP TABLE IF EXISTS `storage_tbl`;
|
||||
CREATE TABLE `storage_tbl` (
|
||||
`id` int(11) NOT NULL AUTO_INCREMENT,
|
||||
`commodity_code` varchar(255) DEFAULT NULL,
|
||||
`count` int(11) DEFAULT 0,
|
||||
PRIMARY KEY (`id`),
|
||||
UNIQUE KEY (`commodity_code`)
|
||||
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
|
||||
|
||||
|
||||
DROP TABLE IF EXISTS `order_tbl`;
|
||||
CREATE TABLE `order_tbl` (
|
||||
`id` int(11) NOT NULL AUTO_INCREMENT,
|
||||
`user_id` varchar(255) DEFAULT NULL,
|
||||
`commodity_code` varchar(255) DEFAULT NULL,
|
||||
`count` int(11) DEFAULT 0,
|
||||
`money` int(11) DEFAULT 0,
|
||||
PRIMARY KEY (`id`)
|
||||
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
|
||||
|
||||
|
||||
DROP TABLE IF EXISTS `account_tbl`;
|
||||
CREATE TABLE `account_tbl` (
|
||||
`id` int(11) NOT NULL AUTO_INCREMENT,
|
||||
`user_id` varchar(255) DEFAULT NULL,
|
||||
`money` int(11) DEFAULT 0,
|
||||
PRIMARY KEY (`id`)
|
||||
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
|
||||
```
|
||||
### Step 4: Start Fescar-Server
|
||||
|
||||
- Download server [package](https://github.com/alibaba/fescar/releases), unzip it.
|
||||
- Start Fescar-Server
|
||||
|
||||
```shell
|
||||
sh fescar-server.sh $LISTEN_PORT $PATH_FOR_PERSISTENT_DATA
|
||||
|
||||
e.g.
|
||||
|
||||
sh fescar-server.sh 8091 /home/admin/fescar/data/
|
||||
```
|
||||
|
||||
### Step 5: Run example
|
||||
|
||||
- Start AccountService ([DubboAccountServiceStarter](https://github.com/fescar-group/fescar-samples/blob/master/dubbo/src/main/java/com/alibaba/fescar/samples/dubbo/starter/DubboAccountServiceStarter.java)).
|
||||
- Start StorageService ([DubboStorageServiceStarter](https://github.com/fescar-group/fescar-samples/blob/master/dubbo/src/main/java/com/alibaba/fescar/samples/dubbo/starter/DubboStorageServiceStarter.java)).
|
||||
- Start OrderService ([DubboOrderServiceStarter](https://github.com/fescar-group/fescar-samples/blob/master/dubbo/src/main/java/com/alibaba/fescar/samples/dubbo/starter/DubboOrderServiceStarter.java)).
|
||||
- Run BusinessService for test ([DubboBusinessTester](https://github.com/fescar-group/fescar-samples/blob/master/dubbo/src/main/java/com/alibaba/fescar/samples/dubbo/starter/DubboBusinessTester.java)).

# 如何使用Fescar保证Dubbo微服务间的一致性
|
||||
|
||||
## 案例
|
||||
|
||||
用户采购商品业务，整个业务包含3个微服务:
|
||||
|
||||
- 库存服务: 扣减给定商品的库存数量。
|
||||
- 订单服务: 根据采购请求生成订单。
|
||||
- 账户服务: 用户账户金额扣减。
|
||||
|
||||
### 业务结构图
|
||||
|
||||
|
||||
|
||||
|
||||
### StorageService
|
||||
|
||||
```java
|
||||
public interface StorageService {
|
||||
|
||||
/**
|
||||
* deduct storage count
|
||||
*/
|
||||
void deduct(String commodityCode, int count);
|
||||
}
|
||||
```
|
||||
|
||||
### OrderService
|
||||
|
||||
```java
|
||||
public interface OrderService {
|
||||
|
||||
/**
|
||||
* create order
|
||||
*/
|
||||
Order create(String userId, String commodityCode, int orderCount);
|
||||
}
|
||||
```
|
||||
|
||||
### AccountService
|
||||
|
||||
```java
|
||||
public interface AccountService {
|
||||
|
||||
/**
|
||||
* debit balance of user's account
|
||||
*/
|
||||
void debit(String userId, int money);
|
||||
}
|
||||
```
|
||||
|
||||
### 主要的业务逻辑：
|
||||
|
||||
```java
|
||||
public class BusinessServiceImpl implements BusinessService {
|
||||
|
||||
private StorageService storageService;
|
||||
|
||||
private OrderService orderService;
|
||||
|
||||
/**
|
||||
* purchase
|
||||
*/
|
||||
public void purchase(String userId, String commodityCode, int orderCount) {
|
||||
|
||||
storageService.deduct(commodityCode, orderCount);
|
||||
|
||||
orderService.create(userId, commodityCode, orderCount);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```java
|
||||
public class StorageServiceImpl implements StorageService {
|
||||
|
||||
private StorageDAO storageDAO;
|
||||
|
||||
@Override
|
||||
public void deduct(String commodityCode, int count) {
|
||||
Storage storage = new Storage();
|
||||
storage.setCount(count);
|
||||
storage.setCommodityCode(commodityCode);
|
||||
storageDAO.update(storage);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```java
|
||||
public class OrderServiceImpl implements OrderService {
|
||||
|
||||
private OrderDAO orderDAO;
|
||||
|
||||
private AccountService accountService;
|
||||
|
||||
public Order create(String userId, String commodityCode, int orderCount) {
|
||||
|
||||
int orderMoney = calculate(commodityCode, orderCount);
|
||||
|
||||
accountService.debit(userId, orderMoney);
|
||||
|
||||
Order order = new Order();
|
||||
order.userId = userId;
|
||||
order.commodityCode = commodityCode;
|
||||
order.count = orderCount;
|
||||
order.money = orderMoney;
|
||||
|
||||
return orderDAO.insert(order);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Fescar 分布式事务解决方案
|
||||
|
||||
|
||||
|
||||
此处仅仅需要一行注解 `@GlobalTransactional` 写在业务发起方的方法上:
|
||||
|
||||
```java
|
||||
|
||||
@GlobalTransactional
|
||||
public void purchase(String userId, String commodityCode, int orderCount) {
|
||||
......
|
||||
}
|
||||
```
|
||||
|
||||
## Dubbo 与 Fescar 结合的例子
|
||||
|
||||
### Step 1: 安装数据库
|
||||
|
||||
- 要求: MySQL (InnoDB 存储引擎)。
|
||||
|
||||
**提示:** 事实上例子中3个微服务需要3个独立的数据库，但为了方便我们使用同一物理库并配置3个逻辑连接串。
|
||||
|
||||
更改以下xml文件中的数据库url、username和password
|
||||
|
||||
dubbo-account-service.xml
|
||||
dubbo-order-service.xml
|
||||
dubbo-storage-service.xml
|
||||
|
||||
```xml
|
||||
<property name="url" value="jdbc:mysql://x.x.x.x:3306/xxx" />
|
||||
<property name="username" value="xxx" />
|
||||
<property name="password" value="xxx" />
|
||||
```
|
||||
### Step 2: 为 Fescar 创建 UNDO_LOG 表
|
||||
|
||||
`UNDO_LOG` 此表用于 Fescar 的AT模式。
|
||||
|
||||
```sql
|
||||
CREATE TABLE `undo_log` (
|
||||
`id` bigint(20) NOT NULL AUTO_INCREMENT,
|
||||
`branch_id` bigint(20) NOT NULL,
|
||||
`xid` varchar(100) NOT NULL,
|
||||
`rollback_info` longblob NOT NULL,
|
||||
`log_status` int(11) NOT NULL,
|
||||
`log_created` datetime NOT NULL,
|
||||
`log_modified` datetime NOT NULL,
|
||||
`ext` varchar(100) DEFAULT NULL,
|
||||
PRIMARY KEY (`id`),
|
||||
KEY `idx_unionkey` (`xid`,`branch_id`)
|
||||
) ENGINE=InnoDB AUTO_INCREMENT=159 DEFAULT CHARSET=utf8
|
||||
```
|
||||
|
||||
### Step 3: 创建相关业务表
|
||||
|
||||
```sql
|
||||
|
||||
DROP TABLE IF EXISTS `storage_tbl`;
|
||||
CREATE TABLE `storage_tbl` (
|
||||
`id` int(11) NOT NULL AUTO_INCREMENT,
|
||||
`commodity_code` varchar(255) DEFAULT NULL,
|
||||
`count` int(11) DEFAULT 0,
|
||||
PRIMARY KEY (`id`),
|
||||
UNIQUE KEY (`commodity_code`)
|
||||
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
|
||||
|
||||
|
||||
DROP TABLE IF EXISTS `order_tbl`;
|
||||
CREATE TABLE `order_tbl` (
|
||||
`id` int(11) NOT NULL AUTO_INCREMENT,
|
||||
`user_id` varchar(255) DEFAULT NULL,
|
||||
`commodity_code` varchar(255) DEFAULT NULL,
|
||||
`count` int(11) DEFAULT 0,
|
||||
`money` int(11) DEFAULT 0,
|
||||
PRIMARY KEY (`id`)
|
||||
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
|
||||
|
||||
|
||||
DROP TABLE IF EXISTS `account_tbl`;
|
||||
CREATE TABLE `account_tbl` (
|
||||
`id` int(11) NOT NULL AUTO_INCREMENT,
|
||||
`user_id` varchar(255) DEFAULT NULL,
|
||||
`money` int(11) DEFAULT 0,
|
||||
PRIMARY KEY (`id`)
|
||||
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
|
||||
```
|
||||
### Step 4: 启动 Fescar-Server 服务
|
||||
|
||||
- 下载Server [package](https://github.com/alibaba/fescar/releases), 并解压。
|
||||
- 运行bin目录下的启动脚本。
|
||||
|
||||
```shell
|
||||
sh fescar-server.sh $LISTEN_PORT $PATH_FOR_PERSISTENT_DATA
|
||||
|
||||
e.g.
|
||||
|
||||
sh fescar-server.sh 8091 /home/admin/fescar/data/
|
||||
```
|
||||
|
||||
### Step 5: 运行例子
|
||||
|
||||
- 启动账户服务 ([DubboAccountServiceStarter](https://github.com/fescar-group/fescar-samples/blob/master/dubbo/src/main/java/com/alibaba/fescar/samples/dubbo/starter/DubboAccountServiceStarter.java))。
|
||||
- 启动库存服务 ([DubboStorageServiceStarter](https://github.com/fescar-group/fescar-samples/blob/master/dubbo/src/main/java/com/alibaba/fescar/samples/dubbo/starter/DubboStorageServiceStarter.java))。

The meta directory is `$HOME/.small-dragonfly/meta`.
|

|
||||
This directory caches the address list of the local node (IP, hostname, IDC, security domain, and so on), managing nodes, and supernodes.
|
||||
|
||||
When started for the first time, the Seata client will access the managing node. The managing node will retrieve the security domains, IDC, geo-location, and more information of this node by querying armory, and assign the most suitable SuperNode. The managing node also distributes the address lists of all other supernodes. dfget stores the above information in the meta directory on the local drive. When the next job is started, dfget reads the meta information from this directory, avoiding accessing the managing node repeatedly.

dfget always finds the most suitable assigned node to register. If fails, it requests other supernodes in order. If all fail, then it requests the managing node once again, updates the meta information, and repeats the above steps. If still fails, then the job fails.

# What Is Fescar?
|
||||
|
||||
Fescar is an intelligent P2P-based image and file distribution tool. It aims to improve the efficiency and success rate of file transferring, and maximize the usage of network bandwidth, especially for the distribution of larget amounts of data, such as application distribution, cache distribution, log distribution, and image distribution.
|
||||
|
||||
At Alibaba, every month Fescar is invoked two billion times and distributes 3.4PB of data. Fescar has become one of the most important pieces of infrastructure at Alibaba.
|
||||
|
||||
While container technologies makes DevOps life easier most of the time, it surely brings some challenges: for example the efficiency of image distribution, especially when you have to replicate image distribution on several hosts.
|
||||
|
||||
Fescar works extremely well with both Docker and [PouchContainer](https://github.com/alibaba/pouch) in this scenario. It's also compatible with containers of other formats. It delivers up to 57 times the throughput of native docker and saves up to 99.5% of the out bandwidth of registry.
|
||||
|
||||
Fescar makes it simple and cost-effective to set up, operate, and scale any kind of file, image, or data distribution.
|
||||
|
||||
## Why Fescar
|
||||
|
||||
This project is an open-source version of the Fescar used at Alibaba. It has the following features:
|
||||
|
||||
**Note:** More Alibaba-internal features will be made available to open-source users soon. Stay tuned!
|
||||
|
||||
- **P2P-based file distribution**: By using the P2P technology for file transmission, it makes the most out of the bandwidth resources of each peer to improve downloading efficiency, and saves a lot of cross-IDC bandwidth, especially the costly cross-board bandwidth.
|
||||
- **Non-invasive support to all kinds of container technologies**: Fescar can seamlessly support various containers for distributing images.
|
||||
- **Host level speed limit**: In addition to rate limit for the current download task like many other downloading tools (for example wget and curl), Fescar also provides rate limit for the entire host.
|
||||
- **Passive CDN**: The CDN mechanism can avoid repetitive remote downloads.
|
||||
- **Strong consistency**: Fescar can make sure that all downloaded files are consistent even if users do not provide any check code (MD5).
|
||||
- **Disk protection and highly efficient IO**: Prechecking disk space, delaying synchronization, writing file blocks in the best order, isolating net-read/disk-write, and so on.
|
||||
- **High performance**: Cluster Manager is completely closed-loop, which means that it doesn't rely on any database or distributed cache, processing requests with extremely high performance.
|
||||
- **Auto-isolation of Exception**: Fescar will automatically isolate exception nodes (peer or Cluster Manager) to improve download stability.
|
||||
- **No pressure on file source**: Generally, only a few Cluster Managers will download files from the source.
|
||||
- **Support standard HTTP header**: Support submitting authentication information through HTTP header.
|
||||
- **Effective concurrency control of Registry Auth**: Reduce the pressure on the Registry Auth Service.
|
||||
- **Simple and easy to use**: Very few configurations are needed.
|
||||
|
||||
## How Does It Stack Up Against Traditional Solution?
|
||||
|
||||
We carried out an experiment to compare the performance of Fescar and wget.
|
||||
|
||||
|Test Environment ||
|
||||
|---|---|
|
||||
|Fescar Server|2 * (24-Core 64GB-RAM 2000Mb/s)|
|
||||
|File Source Server|2 * (24-Core 64GB-RAM 2000Mb/s)|
|
||||
|Client|4-Core 8GB-RAM 200Mb/s|
|
||||
|Target File Size|200MB|
|
||||
|Experiment Date|April 20, 2016|
|
||||
|
||||
The expeirment result is as shown in the following figure.
|
||||
|
||||
|
||||
|
||||
As you can see in the chart, for Fescar, no matter how many clients are downloading, the average downloading time is always about 12 seconds. But for wget, the downloading time keeps increasing with the number of clients. When the number of wget clients reaches 1,200, the file source crashed and therefore cannot serve any client.
|
||||
|
||||
## How Does It Work?
|
||||
|
||||
Fescar works slightly differently when downloading general files and downloading container images.
|
||||
|
||||
### Downloading General Files
|
||||
|
||||
The Cluster Manager is also called a SuperNode, which is responsible for CDN and scheduling every peer to transfer blocks between each other. dfget is the P2P client, which is also called "peer". It's mainly used to download and share blocks.
|
||||
|
||||
|
||||
|
||||
### Downloading Container Images
|
||||
|
||||
Registry is similar to the file server above. dfget proxy is also called dfdaemon, which intercepts HTTP requests from docker pull or docker push, and then decides which requests to process with dfget.
|
||||
|
||||
|
||||
|
||||
### Downloading Blocks
|
||||
|
||||
Every file is divided into multiple blocks, which are transmitted between peers. Each peer is a P2P client. Cluster Manager will check if the corresponding file exists in the local disk. If not, it will be downloaded into Cluster Manager from file server.

# Fescar AT 模式
|
||||
|
||||
## 前提
|
||||
|
||||
- 基于支持本地 ACID 事务的关系型数据库。
|
||||
- Java 应用，通过 JDBC 访问数据库。
|
||||
|
||||
## 整体机制
|
||||
|
||||
两阶段提交协议的演变：
|
||||
|
||||
- 一阶段：业务数据和回滚日志记录在同一个本地事务中提交，释放本地锁和连接资源。
|
||||
- 二阶段：
|
||||
|
||||
- 提交异步化，非常快速地完成。
|
||||
- 回滚通过一阶段的回滚日志进行反向补偿。
|
||||
|
||||
|
||||
# 写隔离
|
||||
|
||||
- 一阶段本地事务提交前，需要确保先拿到 **全局锁** 。
|
||||
- 拿不到 **全局锁** ，不能提交本地事务。
|
||||
- 拿 **全局锁** 的尝试被限制在一定范围内，超出范围将放弃，并回滚本地事务，释放本地锁。
|
||||
|
||||
以一个示例来说明：
|
||||
|
||||
两个全局事务 tx1 和 tx2，分别对 a 表的 m 字段进行更新操作，m 的初始值 1000。
|
||||
|
||||
tx1 先开始，开启本地事务，拿到本地锁，更新操作 m = 1000 - 100 = 900。本地事务提交前，先拿到该记录的 **全局锁** ，本地提交释放本地锁。
|
||||
tx2 后开始，开启本地事务，拿到本地锁，更新操作 m = 900 - 100 = 800。本地事务提交前，尝试拿该记录的 **全局锁** ，tx1 全局提交前，该记录的全局锁被 tx1 持有，tx2 需要重试等待 **全局锁** 。
|
||||
|
||||
|
||||
|
||||
tx1 二阶段全局提交，释放 **全局锁** 。tx2 拿到 **全局锁** 提交本地事务。
|
||||
|
||||
|
||||
|
||||
如果 tx1 的二阶段全局回滚，则 tx1 需要重新获取该数据的本地锁，进行反向补偿的更新操作，实现分支的回滚。
|
||||
|
||||
此时，如果 tx2 仍在等待该数据的 **全局锁**，同时持有本地锁，则 tx1 的分支回滚会失败。分支的回滚会一直重试，直到 tx2 的 **全局锁** 等锁超时，放弃 **全局锁** 并回滚本地事务释放本地锁，tx1 的分支回滚最终成功。
|
||||
|
||||
因为整个过程 **全局锁** 在 tx1 结束前一直是被 tx1 持有的，所以不会发生 **脏写** 的问题。
|
||||
|
||||
# 读隔离
|
||||
|
||||
在数据库本地事务隔离级别 **读已提交（Read Committed）** 或以上的基础上，Fescar（AT 模式）的默认全局隔离级别是 **读未提交（Read Uncommitted）** 。
|
||||
|
||||
如果应用在特定场景下，必需要求全局的 **读已提交** ，目前 Fescar 的方式是通过 SELECT FOR UPDATE 语句的代理。
|
||||
|
||||
|
||||
|
||||
SELECT FOR UPDATE 语句的执行会申请 **全局锁** ，如果 **全局锁** 被其他事务持有，则释放本地锁（回滚 SELECT FOR UPDATE 语句的本地执行）并重试。这个过程中，查询是被 block 住的，直到 **全局锁** 拿到，即读取的相关数据是 **已提交** 的，才返回。
|
||||
|
||||
出于总体性能上的考虑，Fescar 目前的方案并没有对所有 SELECT 语句都进行代理，仅针对 FOR UPDATE 的 SELECT 语句。
|
||||
|
||||
# 工作机制
|
||||
|
||||
以一个示例来说明整个 AT 分支的工作过程。
|
||||
|
||||
业务表：`product`
|
||||
|
||||
| Field | Type | Key|
|
||||
|---------------|--------------|----|
|
||||
| id | bigint(20) |PRI |
|
||||
| name | varchar(100) | |
|
||||
| since | varchar(100) | |
|
||||
|
||||
AT 分支事务的业务逻辑：
|
||||
|
||||
```sql
|
||||
update product set name = 'GTS' where name = 'TXC';
|
||||
```
|
||||
## 一阶段
|
||||
|
||||
过程：
|
||||
|
||||
1. 解析 SQL：得到 SQL 的类型（UPDATE），表（product），条件（where name = 'TXC'）等相关的信息。
|
||||
2. 查询前镜像：根据解析得到的条件信息，生成查询语句，定位数据。
|
||||
|
||||
```sql
|
||||
select id, name, since from product where name = 'TXC';
|
||||
```
|
||||
得到前镜像：
|
||||
|
||||
|id|name|since|
|
||||
|---|---|---|
|
||||
|1|TXC|2014|
|
||||
|
||||
|
||||
3. 执行业务 SQL：更新这条记录的 name 为 'GTS'。
|
||||
4. 查询后镜像：根据前镜像的结果，通过 **主键** 定位数据。
|
||||
|
||||
```sql
|
||||
select id, name, since from product where id = 1`;
|
||||
```
|
||||
得到后镜像：
|
||||
|
||||
|id|name|since|
|
||||
|---|---|---|
|
||||
|1|GTS|2014|
|
||||
|
||||
5. 插入回滚日志：把前后镜像数据以及业务 SQL 相关的信息组成一条回滚日志记录，插入到 `UNDO_LOG` 表中。
|
||||
|
||||
```json
|
||||
{
|
||||
"branchId": 641789253,
|
||||
"undoItems": [{
|
||||
"afterImage": {
|
||||
"rows": [{
|
||||
"fields": [{
|
||||
"name": "id",
|
||||
"type": 4,
|
||||
"value": 1
|
||||
}, {
|
||||
"name": "name",
|
||||
"type": 12,
|
||||
"value": "GTS"
|
||||
}, {
|
||||
"name": "since",
|
||||
"type": 12,
|
||||
"value": "2014"
|
||||
}]
|
||||
}],
|
||||
"tableName": "product"
|
||||
},
|
||||
"beforeImage": {
|
||||
"rows": [{
|
||||
"fields": [{
|
||||
"name": "id",
|
||||
"type": 4,
|
||||
"value": 1
|
||||
}, {
|
||||
"name": "name",
|
||||
"type": 12,
|
||||
"value": "TXC"
|
||||
}, {
|
||||
"name": "since",
|
||||
"type": 12,
|
||||
"value": "2014"
|
||||
}]
|
||||
}],
|
||||
"tableName": "product"
|
||||
},
|
||||
"sqlType": "UPDATE"
|
||||
}],
|
||||
"xid": "xid:xxx"
|
||||
}
|
||||
```
|
||||
|
||||
6. 提交前，向 TC 注册分支：申请 `product` 表中，主键值等于 1 的记录的 **全局锁** 。
|
||||
7. 本地事务提交：业务数据的更新和前面步骤中生成的 UNDO LOG 一并提交。
|
||||
8. 将本地事务提交的结果上报给 TC。
|
||||
|
||||
## 二阶段-回滚
|
||||
|
||||
1. 收到 TC 的分支回滚请求，开启一个本地事务，执行如下操作。
|
||||
2. 通过 XID 和 Branch ID 查找到相应的 UNDO LOG 记录。
|
||||
3. 数据校验：拿 UNDO LOG 中的后镜与当前数据进行比较，如果有不同，说明数据被当前全局事务之外的动作做了修改。这种情况，需要根据配置策略来做处理，详细的说明在另外的文档中介绍。
|
||||
4. 根据 UNDO LOG 中的前镜像和业务 SQL 的相关信息生成并执行回滚的语句：
|
||||
|
||||
```sql
|
||||
update product set name = 'TXC' where id = 1;
|
||||
```
|
||||
|
||||
5. 提交本地事务。并把本地事务的执行结果（即分支事务回滚的结果）上报给 TC。
|
||||
|
||||
## 二阶段-提交
|
||||
|
||||
1. 收到 TC 的分支提交请求，把请求放入一个异步任务的队列中，马上返回提交成功的结果给 TC。
|
||||
2. 异步任务阶段的分支提交请求将异步和批量地删除相应 UNDO LOG 记录。
|
||||
|
||||
|
||||

||||

||||
## 回滚日志表
|
||||
|
||||
UNDO_LOG Table：不同数据库在类型上会略有差别。
|
||||
|
||||
以 MySQL 为例：
|
||||
|
||||
| Field | Type |
|
||||
|---------------|--------------|
|
||||
| branch_id | bigint PK|
|
||||
| xid | varchar(100) |
|
||||
| rollback_info | longblob |
|
||||
| log_status | tinyint |
|
||||
| log_created | datetime |
|
||||
| log_modified | datetime |
|
||||
| ext | varchar(100) |
|
||||
|
||||
```sql
|
||||
-- 注意此处0.3.0+ 增加唯一索引 ux_undo_log
|
||||
CREATE TABLE `undo_log` (
|
||||
`id` bigint(20) NOT NULL AUTO_INCREMENT,
|
||||
`branch_id` bigint(20) NOT NULL,
|
||||
`xid` varchar(100) NOT NULL,

|
||||
UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`)
|
||||
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

### Metrics
|
||||
#### 设计思路
|
||||
1. Fescar作为一个被集成的数据一致性框架，Metrics模块将尽可能少的使用第三方依赖以降低发生冲突的风险；
|
||||
2. Metrics模块将竭力争取更高的度量性能和更低的资源开销，尽可能降低开启后带来的副作用；
|
||||
3. 插件式——Metrics是否激活、数据如何发布，去取决于是否引入了对应的依赖，例如在TC Server中引入`fescar-metrics-prometheus`，则自动启用并将度量数据发布到[Prometheus](https://github.com/prometheus)；
|
||||
4. 不使用Spring，使用SPI(Service Provider Interface)加载扩展；
|
||||
5. 初始仅发布核心Transaction相关指标，之后结合社区的需求，逐步完善运维方面的所有其他指标。
|
||||
|
||||
#### 模块说明
|
||||
由1个核心API模块`fescar-metrics-api`和N个对接实现模块如`fescar-metrics-prometheus`构成：
|
||||
- fescar-metrics-api模块
|
||||
|
||||
此模块是Metrics的核心，将作为Fescar基础架构的一部分被TC、TM和RM引用，它内部**没有任何具体实现代码**，仅包含接口定义，定义的内容包括：
|
||||
1. Meter类接口：`Gauge`、`Counter`、`Timer`...
|
||||
2. 注册容器接口`Registry`
|
||||
3. Measurement发布接口`Publisher`
|
||||
|
||||
>提示：Metrics本身在开源领域也已有很多实现，例如
|
||||
>1. [Netflix-Spectator](https://github.com/Netflix/spectator)
|
||||
>2. [Dropwizard-Metrics](https://github.com/dropwizard/metrics)
|
||||
>3. [Dubbo-Metrics](https://github.com/dubbo/dubbo-metrics)
|
||||
|
||||
>它们有的轻而敏捷，有的重而强大，由于也是“实现”，因此不会纳入`fescar-metrics-api`中，避免实现绑定。
|
||||
|
||||
- fescar-metrics-prometheus模块
|
||||
|
||||
这是我们默认提供的Metrics实现，不使用其它Metrics开源实现，并轻量级的实现了以下三个Meter：
|
||||
|
||||
| Meter类型 | 描述 |
|
||||
| --------- | ------------------------------------------------------------ |
|
||||
| Gauge | 单一最新值度量器 |
|
||||
| Counter | 单一累加度量器，可增可减 |
|
||||
| Summary | 多Measurement输出计数器，将输出`total`(合计)、`count`(计数)、`max`(最大)、`average`(合计/计数)和`tps`(合计/时间间隔)，无单位 |
|
||||
| Timer | 多Measurement输出计时器，将输出`total`(合计)、`count`(计数)、`max`(最大)和`average`(合计/计数)，支持微秒为单位累计 |
|
||||
|
||||
>说明：
|
||||
>1. 未来可能增加更丰富复杂的度量器例如Histogram，这是一种可以本地统计聚合75th, 90th, 95th, 98th, 99th,99.9th...的度量器，适合某些场合，但需要更多内存。
|
||||
>2. 所有的计量器都将继承自Meter，所有的计量器执行measure()方法后，都将归一化的生成1或N个Measurement结果。
|
||||
|
||||
它也会实现一个内存的Registry和PrometheusExporter，将度量数据同步给Prometheus。
|
||||
|
||||
>说明：不同的监控系统，采集度量数据的方式不尽相同，例如Zabbix支持用zabbix-agent推送，Prometheus则推荐使用prometheus-server[拉取](https://prometheus.io/docs/practices/pushing/)的方式；同样数据交换协议也不同，因此往往需要逐一适配。
|
||||
|
||||
#### 如何使用
|
||||
##### 引入依赖
|
||||
如果需要开启TC的Metrics，只需要在`fescar-server`的pom中增加：
|
||||
```xml
|
||||
<dependencies>
|
||||
<dependency>
|
||||
<groupId>${project.groupId}</groupId>
|
||||
<artifactId>fescar-core</artifactId>
|
||||
</dependency>
|
||||
<!--导入依赖，启用Metrics-->
|
||||
<dependency>
|
||||
<groupId>${project.groupId}</groupId>
|
||||
<artifactId>fescar-metrics-prometheus</artifactId>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>commons-lang</groupId>
|
||||
<artifactId>commons-lang</artifactId>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>org.testng</groupId>
|
||||
<artifactId>testng</artifactId>
|
||||
<scope>test</scope>
|
||||
</dependency>
|
||||
</dependencies>
|
||||
```
|
||||
|
||||
之后启动TC，即可在`http://tc-server-ip:9898/metrics`上获取到Metrics的文本格式数据。
|
||||
|
||||
>提示：默认使用`9898`端口，Prometheus已登记的端口列表[在此](https://github.com/prometheus/prometheus/wiki/Default-port-allocations)，如果想更换端口，可通过`metrics.exporter.prometheus.port`配置修改。
|
||||
|
||||
##### 下载并启动Prometheus
|
||||
下载完毕后，修改Prometheus的配置文件`prometheus.yml`，在`scrape_configs`中增加一项抓取Fescar的度量数据：
|
||||
```yaml
|
||||
scrape_configs:
|
||||
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
|
||||
- job_name: 'prometheus'
|
||||
|
||||
# metrics_path defaults to '/metrics'
|
||||
# scheme defaults to 'http'.
|
||||
|
||||
static_configs:
|
||||
- targets: ['localhost:9090']
|
||||
|
||||
- job_name: 'fescar'
|
||||
|
||||
# metrics_path defaults to '/metrics'
|
||||
# scheme defaults to 'http'.
|
||||
|
||||
static_configs:
|
||||
- targets: ['tc-server-ip:9898']
|
||||
```
|
||||
|
||||
##### 查看数据输出
|
||||
推荐结合配置[Grafana](https://prometheus.io/docs/visualization/grafana/)获得更好的查询效果，初期Fescar导出的Metrics包括：
|
||||
- TC :
|
||||
|
||||
| Metrics | 描述 |
|
||||
| ------ | --------- |
|
||||
| fescar.transaction(role=tc,meter=counter,status=active/committed/rollback) | 当前活动中/已提交/已回滚的事务总数 |
|
||||
| fescar.transaction(role=tc,meter=summary,statistic=count,status=committed/rollback) | 当前周期内提交/回滚的事务数 |
|
||||
| fescar.transaction(role=tc,meter=summary,statistic=tps,status=committed/rollback) | 当前周期内提交/回滚的事务TPS(transaction per second) |
|
||||
| fescar.transaction(role=tc,meter=timer,statistic=total,status=committed/rollback) | 当前周期内提交/回滚的事务耗时总和 |
|
||||
| fescar.transaction(role=tc,meter=timer,statistic=count,status=committed/rollback) | 当前周期内提交/回滚的事务数 |
|
||||
| fescar.transaction(role=tc,meter=timer,statistic=average,status=committed/rollback) | 当前周期内提交/回滚的事务平均耗时 |
|
||||
| fescar.transaction(role=tc,meter=timer,statistic=max,status=committed/rollback) | 当前周期内提交/回滚的事务最大耗时 |
|
||||
|
||||
>提示：fescar.transaction(role=tc,meter=summary,statistic=count,status=committed/rollback)和fescar.transaction(role=tc,meter=timer,statistic=count,status=committed/rollback)的值可能相同，但它们来源于两个不同的度量器。
|
||||
|
||||
- TM：
|
||||
|
||||
稍后实现，包括诸如：
|
||||
fescar.transaction(role=tm,name={GlobalTransactionalName},meter=counter,status=active/committed/rollback) : 以GlobalTransactionalName为维度区分不同Transactional的状态。
|
||||
|
||||
- RM：
|
||||
|
||||
稍后实现，包括诸如：
|
||||
fescar.transaction(role=rm,name={BranchTransactionalName},mode=at/mt,meter=counter,status=active/committed/rollback)：以BranchTransactionalName为维度以及AT/MT维度区分不同分支Transactional的状态。
|
||||
|
||||
#### 如何扩展
|
||||
如果有下面几种情况：
|
||||
1. 您不是使用Prometheus作为运维监控系统，但希望能够将Fescar的Metrics数据集成进Dashboard中；
|
||||
2. 您需要更复杂强大的度量器类型，这些度量器在其他Metrics实现库中已有，希望集成这些第三方依赖直接使用；
|
||||
3. 您需要改变默认Metric的Measurement输出，例如在Timer中增加一个`min`或`sd`(方差)；
|
||||
4. ...
|
||||
|
||||
那么需要自行扩展Metrics的实现，请创建新的模块项目例如`fescar-metrics-xxxx`，之后：
|
||||
- 针对1：您需要实现新的Exporter；
|
||||
- 针对2：您可以改变默认Registry的实现，返回第三方的Meter计量器实现；
|
||||
- 针对3：您可以修改对应Meter的实现，包括`measure()`方法返回的Measurement列表。

# Fescar TCC 模式
|
||||
|
||||
回顾总览中的描述：一个分布式的全局事务，整体是 **两阶段提交** 的模型。全局事务是由若干分支事务组成的，分支事务要满足 **两阶段提交** 的模型要求，即需要每个分支事务都具备自己的：
|
||||
|
||||
- 一阶段 prepare 行为
|
||||
- 二阶段 commit 或 rollback 行为
|
||||
|
||||
|
||||
|
||||
根据两阶段行为模式的不同，我们将分支事务划分为 **Automatic (Branch) Transaction Mode** 和 **TCC (Branch) Transaction Mode**.
|
||||
|
||||
AT 模式（[参考链接 TBD]()）基于 **支持本地 ACID 事务** 的 **关系型数据库**：
|
||||
|
||||
- 一阶段 prepare 行为：在本地事务中，一并提交业务数据更新和相应回滚日志记录。
|
||||
- 二阶段 commit 行为：马上成功结束，**自动** 异步批量清理回滚日志。
|
||||
- 二阶段 rollback 行为：通过回滚日志，**自动** 生成补偿操作，完成数据回滚。
|
||||
|
||||
相应的，TCC 模式，不依赖于底层数据资源的事务支持：
|
||||
|
||||
- 一阶段 prepare 行为：调用 **自定义** 的 prepare 逻辑。
|
||||
- 二阶段 commit 行为：调用 **自定义** 的 commit 逻辑。
|
||||
- 二阶段 rollback 行为：调用 **自定义** 的 rollback 逻辑。
|
||||
|
||||
所谓 TCC 模式，是指支持把 **自定义** 的分支事务纳入到全局事务的管理中。

|
||||
Fescar支持在TC、TM和RM三个角色开启Metrics数据采集并输出到Prometheus监控系统中。
|
||||
### 在TC中配置开启Metrics
|
||||
#### 步骤一：在Seata Server中增加Metrics的依赖并重新编译Server
|
||||
打开Seata Server源代码的[pom](https://github.com/alibaba/seata/blob/develop/server/pom.xml)，添加Metrics依赖：
|
||||
#### 步骤一：在Fescar Server中增加Metrics的依赖并重新编译Server
|
||||
打开Fescar Server源代码的[pom](https://github.com/alibaba/fescar/blob/develop/server/pom.xml)，添加Metrics依赖：
|
||||
|
||||
```xml
|
||||
<dependency>
|
||||
<groupId>${project.groupId}</groupId>
|
||||
<artifactId>seata-metrics-prometheus</artifactId>
|
||||
<artifactId>fescar-metrics-prometheus</artifactId>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
重新编译Server，启动，输入`http://tc-server-ip:9898/metrics`，即可获得最新的Metrics数据，例如：
|
||||
```

# 什么是 Fescar?
|
||||
|
||||
|
||||
Fescar 是一款开源的分布式事务解决方案，致力于提供高性能和简单易用的分布式事务服务。Fescar 将为用户提供了 AT、TCC 和 XA 事务模式，为用户打造一站式的分布式解决方案。
|
||||
|
||||
# AT 模式
|
||||
|
||||
## 前提
|
||||
|
||||
- 基于支持本地 ACID 事务的关系型数据库。
|
||||
- Java 应用，通过 JDBC 访问数据库。
|
||||
|
||||
## 整体机制
|
||||
|
||||
两阶段提交协议的演变：
|
||||
|
||||
- 一阶段：业务数据和回滚日志记录在同一个本地事务中提交，释放本地锁和连接资源。
|
||||
- 二阶段：
|
||||
|
||||
- 提交异步化，非常快速地完成。
|
||||
- 回滚通过一阶段的回滚日志进行反向补偿。
|
||||
|
||||
|
||||
# 写隔离
|
||||
|
||||
- 一阶段本地事务提交前，需要确保先拿到 **全局锁** 。
|
||||
- 拿不到 **全局锁** ，不能提交本地事务。
|
||||
- 拿 **全局锁** 的尝试被限制在一定范围内，超出范围将放弃，并回滚本地事务，释放本地锁。
|
||||
|
||||
以一个示例来说明：
|
||||
|
||||
两个全局事务 tx1 和 tx2，分别对 a 表的 m 字段进行更新操作，m 的初始值 1000。
|
||||
|
||||
tx1 先开始，开启本地事务，拿到本地锁，更新操作 m = 1000 - 100 = 900。本地事务提交前，先拿到该记录的 **全局锁** ，本地提交释放本地锁。
|
||||
tx2 后开始，开启本地事务，拿到本地锁，更新操作 m = 900 - 100 = 800。本地事务提交前，尝试拿该记录的 **全局锁** ，tx1 全局提交前，该记录的全局锁被 tx1 持有，tx2 需要重试等待 **全局锁** 。
|
||||
|
||||
|
||||
|
||||
tx1 二阶段全局提交，释放 **全局锁** 。tx2 拿到 **全局锁** 提交本地事务。
|
||||
|
||||
|
||||
|
||||
如果 tx1 的二阶段全局回滚，则 tx1 需要重新获取该数据的本地锁，进行反向补偿的更新操作，实现分支的回滚。
|
||||
|
||||
此时，如果 tx2 仍在等待该数据的 **全局锁**，同时持有本地锁，则 tx1 的分支回滚会失败。分支的回滚会一直重试，直到 tx2 的 **全局锁** 等锁超时，放弃 **全局锁** 并回滚本地事务释放本地锁，tx1 的分支回滚最终成功。
|
||||
|
||||
因为整个过程 **全局锁** 在 tx1 结束前一直是被 tx1 持有的，所以不会发生 **脏写** 的问题。
|
||||
|
||||
# 读隔离
|
||||
|
||||
在数据库本地事务隔离级别 **读已提交（Read Committed）** 或以上的基础上，Fescar（AT 模式）的默认全局隔离级别是 **读未提交（Read Uncommitted）** 。
|
||||
|
||||
如果应用在特定场景下，必需要求全局的 **读已提交** ，目前 Fescar 的方式是通过 SELECT FOR UPDATE 语句的代理。
|
||||
|
||||
|
||||
|
||||
SELECT FOR UPDATE 语句的执行会申请 **全局锁** ，如果 **全局锁** 被其他事务持有，则释放本地锁（回滚 SELECT FOR UPDATE 语句的本地执行）并重试。这个过程中，查询是被 block 住的，直到 **全局锁** 拿到，即读取的相关数据是 **已提交** 的，才返回。
|
||||
|
||||
出于总体性能上的考虑，Fescar 目前的方案并没有对所有 SELECT 语句都进行代理，仅针对 FOR UPDATE 的 SELECT 语句。
|
||||
|
||||
# 工作机制
|
||||
|
||||
以一个示例来说明整个 AT 分支的工作过程。
|
||||
|
||||
业务表：`product`
|
||||
|
||||
| Field | Type | Key|
|
||||
|---------------|--------------|----|
|
||||
| id | bigint(20) |PRI |
|
||||
| name | varchar(100) | |
|
||||
| since | varchar(100) | |
|
||||
|
||||
AT 分支事务的业务逻辑：
|
||||
|
||||
```sql
|
||||
update product set name = 'GTS' where name = 'TXC';
|
||||
```
|
||||
## 一阶段
|
||||
|
||||
过程：
|
||||
|
||||
1. 解析 SQL：得到 SQL 的类型（UPDATE），表（product），条件（where name = 'TXC'）等相关的信息。
|
||||
2. 查询前镜像：根据解析得到的条件信息，生成查询语句，定位数据。
|
||||
|
||||
```sql
|
||||
select id, name, since from product where name = 'TXC';
|
||||
```
|
||||
得到前镜像：
|
||||
|
||||
|id|name|since|
|
||||
|---|---|---|
|
||||
|1|TXC|2014|
|
||||
|
||||
|
||||
3. 执行业务 SQL：更新这条记录的 name 为 'GTS'。
|
||||
4. 查询后镜像：根据前镜像的结果，通过 **主键** 定位数据。
|
||||
|
||||
```sql
|
||||
select id, name, since from product where id = 1`;
|
||||
```
|
||||
得到后镜像：
|
||||
|
||||
|id|name|since|
|
||||
|---|---|---|
|
||||
|1|GTS|2014|
|
||||
|
||||
5. 插入回滚日志：把前后镜像数据以及业务 SQL 相关的信息组成一条回滚日志记录，插入到 `UNDO_LOG` 表中。
|
||||
|
||||
```json
|
||||
{
|
||||
"branchId": 641789253,
|
||||
"undoItems": [{
|
||||
"afterImage": {
|
||||
"rows": [{
|
||||
"fields": [{
|
||||
"name": "id",
|
||||
"type": 4,
|
||||
"value": 1
|
||||
}, {
|
||||
"name": "name",
|
||||
"type": 12,
|
||||
"value": "GTS"
|
||||
}, {
|
||||
"name": "since",
|
||||
"type": 12,
|
||||
"value": "2014"
|
||||
}]
|
||||
}],
|
||||
"tableName": "product"
|
||||
},
|
||||
"beforeImage": {
|
||||
"rows": [{
|
||||
"fields": [{
|
||||
"name": "id",
|
||||
"type": 4,
|
||||
"value": 1
|
||||
}, {
|
||||
"name": "name",
|
||||
"type": 12,
|
||||
"value": "TXC"
|
||||
}, {
|
||||
"name": "since",
|
||||
"type": 12,
|
||||
"value": "2014"
|
||||
}]
|
||||
}],
|
||||
"tableName": "product"
|
||||
},
|
||||
"sqlType": "UPDATE"
|
||||
}],
|
||||
"xid": "xid:xxx"
|
||||
}
|
||||
```
|
||||
|
||||
6. 提交前，向 TC 注册分支：申请 `product` 表中，主键值等于 1 的记录的 **全局锁** 。
|
||||
7. 本地事务提交：业务数据的更新和前面步骤中生成的 UNDO LOG 一并提交。
|
||||
8. 将本地事务提交的结果上报给 TC。
|
||||
|
||||
## 二阶段-回滚
|
||||
|
||||
1. 收到 TC 的分支回滚请求，开启一个本地事务，执行如下操作。
|
||||
2. 通过 XID 和 Branch ID 查找到相应的 UNDO LOG 记录。
|
||||
3. 数据校验：拿 UNDO LOG 中的后镜与当前数据进行比较，如果有不同，说明数据被当前全局事务之外的动作做了修改。这种情况，需要根据配置策略来做处理，详细的说明在另外的文档中介绍。
|
||||
4. 根据 UNDO LOG 中的前镜像和业务 SQL 的相关信息生成并执行回滚的语句：
|
||||
|
||||
```sql
|
||||
update product set name = 'TXC' where id = 1;
|
||||
```
|
||||
|
||||
5. 提交本地事务。并把本地事务的执行结果（即分支事务回滚的结果）上报给 TC。
|
||||
|
||||
## 二阶段-提交
|
||||
|
||||
1. 收到 TC 的分支提交请求，把请求放入一个异步任务的队列中，马上返回提交成功的结果给 TC。
|
||||
2. 异步任务阶段的分支提交请求将异步和批量地删除相应 UNDO LOG 记录。
|
||||
|
||||
|
||||
# 附录
|
||||
|
||||
## 回滚日志表
|
||||
|
||||
UNDO_LOG Table：不同数据库在类型上会略有差别。
|
||||
|
||||
以 MySQL 为例：
|
||||
|
||||
| Field | Type |
|
||||
|---------------|--------------|
|
||||
| branch_id | bigint PK|
|
||||
| xid | varchar(100) |
|
||||
| rollback_info | longblob |
|
||||
| log_status | tinyint |
|
||||
| log_created | datetime |
|
||||
| log_modified | datetime |
|
||||
| ext | varchar(100) |
|
||||
|
||||
```sql
|
||||
-- 注意此处0.3.0+ 增加唯一索引 ux_undo_log
|
||||
CREATE TABLE `undo_log` (
|
||||
`id` bigint(20) NOT NULL AUTO_INCREMENT,
|
||||
`branch_id` bigint(20) NOT NULL,
|
||||
`xid` varchar(100) NOT NULL,
|
||||
`rollback_info` longblob NOT NULL,
|
||||
`log_status` int(11) NOT NULL,
|
||||
`log_created` datetime NOT NULL,
|
||||
`log_modified` datetime NOT NULL,
|
||||
`ext` varchar(100) DEFAULT NULL,
|
||||
PRIMARY KEY (`id`),
|
||||
UNIQUE KEY `ux_undo_log` (`xid`,`branch_id`)
|
||||
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
|
||||
```
|
||||
|
||||
# TCC 模式
|
||||
|
||||
回顾总览中的描述：一个分布式的全局事务，整体是 **两阶段提交** 的模型。全局事务是由若干分支事务组成的，分支事务要满足 **两阶段提交** 的模型要求，即需要每个分支事务都具备自己的：
|
||||
|
||||
- 一阶段 prepare 行为
|
||||
- 二阶段 commit 或 rollback 行为
|
||||
|
||||
|
||||
|
||||
根据两阶段行为模式的不同，我们将分支事务划分为 **Automatic (Branch) Transaction Mode** 和 **Manual (Branch) Transaction Mode**.
|
||||
|
||||
AT 模式（[参考链接 TBD]()）基于 **支持本地 ACID 事务** 的 **关系型数据库**：
|
||||
|
||||
- 一阶段 prepare 行为：在本地事务中，一并提交业务数据更新和相应回滚日志记录。
|
||||
- 二阶段 commit 行为：马上成功结束，**自动** 异步批量清理回滚日志。
|
||||
- 二阶段 rollback 行为：通过回滚日志，**自动** 生成补偿操作，完成数据回滚。
|
||||
|
||||
相应的，TCC 模式，不依赖于底层数据资源的事务支持：
|
||||
|
||||
- 一阶段 prepare 行为：调用 **自定义** 的 prepare 逻辑。
|
||||
- 二阶段 commit 行为：调用 **自定义** 的 commit 逻辑。
|
||||
- 二阶段 rollback 行为：调用 **自定义** 的 rollback 逻辑。
|
||||
|
||||
所谓 TCC 模式，是指支持把 **自定义** 的分支事务纳入到全局事务的管理中。

<h2>Use case</h2>
|
||||
<p>A business logic for user purchasing commodities. The whole business logic is powered by 3 microservices:</p>
|
||||
<ul>
|
||||
<li>Storage service: deduct storage count on given commodity.</li>
|
||||
<li>Order service: create order according to purchase request.</li>
|
||||
<li>Account service: debit the balance of user's account.</li>
|
||||
</ul>

<h3>Step 1: Setup database</h3>
|
||||
<ul>
|
||||
<li>Requirement: MySQL with InnoDB engine.</li>
|
||||
</ul>
|
||||
<p><strong>Note:</strong> In fact, there should be 3 database for the 3 services in the example use case. However, we can just create one database and configure 3 data sources for simple.</p>
|
||||
<p>Modify Spring XML with the database URL/username/password you just created.</p>
|
||||
<p>dubbo-account-service.xml
|
||||
dubbo-order-service.xml
|
||||
dubbo-storage-service.xml</p>

<h2>What is a SuperNode?</h2>
|
||||
<p>A SuperNode is a long-time process that plays the following roles:</p>
|
||||
<ul>

@ -25,48 +25,48 @@
|

<li>A CDN server that caches downloaded data from source to avoid downloading same files repeatedly.</li>
|
||||
</ul>
|
||||
<h2>What is dfget?</h2>
|
||||
<p>Dfget is the Seata client used for downloading files. It's similar to wget.</p>
|
||||
<p>Dfget is the Fescar client used for downloading files. It's similar to wget.</p>
|
||||
<p>Meanwhile, it also plays the role of a peer, which can transfer data between each other in the P2P network.</p>
|
||||
<h2>What is dfdaemon?</h2>
|
||||
<p>Dfdaemon is only used for pulling images. It establishes a proxy between dockerd/pouchd and registry.</p>
|
||||
<p>Dfdaemon filters out layer fetching requests from all requests sent by dockerd/pouchd when pulling images, then uses dfget to download these layers.</p>
|
||||
<h2>Where is the installation directory of Seata client dfget?</h2>
|
||||
<h2>Where is the installation directory of Fescar client dfget?</h2>
|
||||
<p>Normally, there are two installation directories:</p>
|
||||
<ul>
|
||||
<li>Seata plugin for StarAgent: <code>/home/staragent/plugins/dragonfly/dfget</code></li>
|
||||
<li>Fescar plugin for StarAgent: <code>/home/staragent/plugins/dragonfly/dfget</code></li>
|
||||
<li>StarAgent's built-in dfget: <code>/home/staragent/bin/dfget</code></li>
|
||||
</ul>
|
||||
<p>The Seata plugin is used by default. If the Seata plugin is not installed, then the StarAgent's build-in dfget is used.</p>
|
||||
<h2>Where is the log directory of Seata client dfget?</h2>
|
||||
<p>The Fescar plugin is used by default. If the Fescar plugin is not installed, then the StarAgent's build-in dfget is used.</p>
|
||||
<h2>Where is the log directory of Fescar client dfget?</h2>
|
||||
<p>The log directory is <code>$HOME/.small-dragonfly/logs/dfclient.log</code>.</p>
|
||||
<h2>Where is the data directory of Seata client dfget?</h2>
|
||||
<h2>Where is the data directory of Fescar client dfget?</h2>
|
||||
<p>The data directory is <code>$HOME/.small-dragonfly/data</code>.</p>
|
||||
<p>Each account has its own data directory. A P2P downloading job generates two data files under this directory:</p>
|
||||
<ul>
|
||||
<li>A temporary downloading file for the target file, with the name <code>targetFileName-sign</code>. This file is moved to the target directory after the download is complete.</li>
|
||||
<li>A copy of the temporary downloading file for uploading, with the name <code>targetFileName-sign.service</code>. If no downloading jobs are downloading this file from this node, then it gets cleaned after three minutes. Before the process is completed normally, any file lasting longer than 60 minutes will be purged.</li>
|
||||
</ul>
|
||||
<h2>Where is the meta directory of Seata client dfget?</h2>
|
||||
<h2>Where is the meta directory of Fescar client dfget?</h2>
|
||||
<p>The meta directory is <code>$HOME/.small-dragonfly/meta</code>.</p>
|
||||
<p>This directory caches the address list of the local node (IP, hostname, IDC, security domain, and so on), managing nodes, and supernodes.</p>
|
||||
<p>When started for the first time, the Seata client will access the managing node. The managing node will retrieve the security domains, IDC, geo-location, and more information of this node by querying armory, and assign the most suitable SuperNode. The managing node also distributes the address lists of all other supernodes. dfget stores the above information in the meta directory on the local drive. When the next job is started, dfget reads the meta information from this directory, avoiding accessing the managing node repeatedly.</p>
|
||||
<p>When started for the first time, the Fescar client will access the managing node. The managing node will retrieve the security domains, IDC, geo-location, and more information of this node by querying armory, and assign the most suitable SuperNode. The managing node also distributes the address lists of all other supernodes. dfget stores the above information in the meta directory on the local drive. When the next job is started, dfget reads the meta information from this directory, avoiding accessing the managing node repeatedly.</p>
|
||||
<p>dfget always finds the most suitable assigned node to register. If fails, it requests other supernodes in order. If all fail, then it requests the managing node once again, updates the meta information, and repeats the above steps. If still fails, then the job fails.</p>
|
||||
<p><strong>Tip</strong>: If the dfclient.log suggests that the SuperNode registration fails all the time, try delete all files from the meta directory and try again.</p>
|

<h2>How to check the version of Seata client dfget?</h2>
|
||||
<p>If you have installed the Seata client, run this command:</p>
|
||||
<h2>How to check the version of Fescar client dfget?</h2>
|
||||
<p>If you have installed the Fescar client, run this command:</p>
|
||||
<pre><code class="language-bash">dfget -v
|
||||
</code></pre>
|
||||
<h2>Why is the dfget process still there after the download is complete?</h2>
|
||||
<p>Because Seata adopts a P2P downloading approach, dfget provides uploading services in addition to downloading services. If there are no new jobs within five minutes, the dfget process will be terminated automatically.</p>
|
||||
<h2>How to clean up the data directory of Seata?</h2>
|
||||
<p>Normally, Seata automatically cleans up files which are not accessed in three minutes from the uploading file list, and the residual files that live longer than one hour from the data directory.</p>

<h2>How to clean up the data directory of Fescar?</h2>
|
||||
<p>Normally, Fescar automatically cleans up files which are not accessed in three minutes from the uploading file list, and the residual files that live longer than one hour from the data directory.</p>
|
||||
<p>Follow these steps to clean up the data directory manually:</p>
|
||||
<ol>
|
||||
<li>Identify the account to which the residual files belong.</li>
|
||||
<li>Check if there is any running dfget process started by other accounts.</li>
|
||||
<li>If there is such a process, then terminate the process, and start a dfget process with the account identified at Step 1. This process will automatically clean up the residual files from the data directory.</li>

<p>Fescar is an intelligent P2P-based image and file distribution tool. It aims to improve the efficiency and success rate of file transferring, and maximize the usage of network bandwidth, especially for the distribution of larget amounts of data, such as application distribution, cache distribution, log distribution, and image distribution.</p>
|
||||
<p>At Alibaba, every month Fescar is invoked two billion times and distributes 3.4PB of data. Fescar has become one of the most important pieces of infrastructure at Alibaba.</p>
|
||||
<p>While container technologies makes DevOps life easier most of the time, it surely brings some challenges: for example the efficiency of image distribution, especially when you have to replicate image distribution on several hosts.</p>
|
||||
<p>Seata works extremely well with both Docker and <a href="https://github.com/alibaba/pouch">PouchContainer</a> in this scenario. It's also compatible with containers of other formats. It delivers up to 57 times the throughput of native docker and saves up to 99.5% of the out bandwidth of registry.</p>
|
||||
<p>Seata makes it simple and cost-effective to set up, operate, and scale any kind of file, image, or data distribution.</p>

<li><strong>P2P-based file distribution</strong>: By using the P2P technology for file transmission, it makes the most out of the bandwidth resources of each peer to improve downloading efficiency, and saves a lot of cross-IDC bandwidth, especially the costly cross-board bandwidth.</li>
|
||||
<li><strong>Non-invasive support to all kinds of container technologies</strong>: Seata can seamlessly support various containers for distributing images.</li>
|
||||
<li><strong>Host level speed limit</strong>: In addition to rate limit for the current download task like many other downloading tools (for example wget and curl), Seata also provides rate limit for the entire host.</li>

<li><strong>Disk protection and highly efficient IO</strong>: Prechecking disk space, delaying synchronization, writing file blocks in the best order, isolating net-read/disk-write, and so on.</li>
|
||||
<li><strong>High performance</strong>: Cluster Manager is completely closed-loop, which means that it doesn't rely on any database or distributed cache, processing requests with extremely high performance.</li>
|

<li><strong>Auto-isolation of Exception</strong>: Fescar will automatically isolate exception nodes (peer or Cluster Manager) to improve download stability.</li>
|
||||
<li><strong>No pressure on file source</strong>: Generally, only a few Cluster Managers will download files from the source.</li>
|
||||
<li><strong>Support standard HTTP header</strong>: Support submitting authentication information through HTTP header.</li>
|
||||
<li><strong>Effective concurrency control of Registry Auth</strong>: Reduce the pressure on the Registry Auth Service.</li>
|

<h3>Downloading General Files</h3>
|

<p>The Cluster Manager is also called a SuperNode, which is responsible for CDN and scheduling every peer to transfer blocks between each other. dfget is the P2P client, which is also called "peer". It's mainly used to download and share blocks.</p>

|

<h3>Downloading Blocks</h3>
|
||||
<p>Every file is divided into multiple blocks, which are transmitted between peers. Each peer is a P2P client. Cluster Manager will check if the corresponding file exists in the local disk. If not, it will be downloaded into Cluster Manager from file server.</p>

|
||||
<p>Fescar is an intelligent P2P-based image and file distribution tool. It aims to improve the efficiency and success rate of file transferring, and maximize the usage of network bandwidth, especially for the distribution of larget amounts of data, such as application distribution, cache distribution, log distribution, and image distribution.</p>
|
||||
<p>At Alibaba, every month Fescar is invoked two billion times and distributes 3.4PB of data. Fescar has become one of the most important pieces of infrastructure at Alibaba.</p>
|
||||
<p>While container technologies makes DevOps life easier most of the time, it surely brings some challenges: for example the efficiency of image distribution, especially when you have to replicate image distribution on several hosts.</p>
|
||||
<p>Fescar works extremely well with both Docker and <a href="https://github.com/alibaba/pouch">PouchContainer</a> in this scenario. It's also compatible with containers of other formats. It delivers up to 57 times the throughput of native docker and saves up to 99.5% of the out bandwidth of registry.</p>
|
||||
<p>Fescar makes it simple and cost-effective to set up, operate, and scale any kind of file, image, or data distribution.</p>
|
||||
<h2>Why Fescar</h2>
|
||||
<p>This project is an open-source version of the Fescar used at Alibaba. It has the following features:</p>
|
||||
<p><strong>Note:</strong> More Alibaba-internal features will be made available to open-source users soon. Stay tuned!</p>
|
||||
<ul>
|
||||
<li><strong>P2P-based file distribution</strong>: By using the P2P technology for file transmission, it makes the most out of the bandwidth resources of each peer to improve downloading efficiency, and saves a lot of cross-IDC bandwidth, especially the costly cross-board bandwidth.</li>
|
||||
<li><strong>Non-invasive support to all kinds of container technologies</strong>: Fescar can seamlessly support various containers for distributing images.</li>
|
||||
<li><strong>Host level speed limit</strong>: In addition to rate limit for the current download task like many other downloading tools (for example wget and curl), Fescar also provides rate limit for the entire host.</li>
|
||||
<li><strong>Passive CDN</strong>: The CDN mechanism can avoid repetitive remote downloads.</li>
|
||||
<li><strong>Strong consistency</strong>: Fescar can make sure that all downloaded files are consistent even if users do not provide any check code (MD5).</li>
|
||||
<li><strong>Disk protection and highly efficient IO</strong>: Prechecking disk space, delaying synchronization, writing file blocks in the best order, isolating net-read/disk-write, and so on.</li>
|
||||
<li><strong>High performance</strong>: Cluster Manager is completely closed-loop, which means that it doesn't rely on any database or distributed cache, processing requests with extremely high performance.</li>
|
||||
<li><strong>Auto-isolation of Exception</strong>: Fescar will automatically isolate exception nodes (peer or Cluster Manager) to improve download stability.</li>
|
||||
<li><strong>No pressure on file source</strong>: Generally, only a few Cluster Managers will download files from the source.</li>
|
||||
<li><strong>Support standard HTTP header</strong>: Support submitting authentication information through HTTP header.</li>
|
||||
<li><strong>Effective concurrency control of Registry Auth</strong>: Reduce the pressure on the Registry Auth Service.</li>
|
||||
<li><strong>Simple and easy to use</strong>: Very few configurations are needed.</li>
|
||||
</ul>
|
||||
<h2>How Does It Stack Up Against Traditional Solution?</h2>
|
||||
<p>We carried out an experiment to compare the performance of Fescar and wget.</p>

<p>The expeirment result is as shown in the following figure.</p>
|
||||
<p><img src="../img/performance.png" alt="How it stacks up"></p>
|
||||
<p>As you can see in the chart, for Fescar, no matter how many clients are downloading, the average downloading time is always about 12 seconds. But for wget, the downloading time keeps increasing with the number of clients. When the number of wget clients reaches 1,200, the file source crashed and therefore cannot serve any client.</p>
|
||||
<h2>How Does It Work?</h2>
|
||||
<p>Fescar works slightly differently when downloading general files and downloading container images.</p>
|
||||
<h3>Downloading General Files</h3>
|
||||
<p>The Cluster Manager is also called a SuperNode, which is responsible for CDN and scheduling every peer to transfer blocks between each other. dfget is the P2P client, which is also called "peer". It's mainly used to download and share blocks.</p>
|
||||
<p><img src="../img/dfget.png" alt="Downloading General Files"></p>
|
||||
<h3>Downloading Container Images</h3>
|
||||
<p>Registry is similar to the file server above. dfget proxy is also called dfdaemon, which intercepts HTTP requests from docker pull or docker push, and then decides which requests to process with dfget.</p>
|
||||
<p><img src="../img/dfget-combine-container.png" alt="Downloading Container Images"></p>
|
||||
<h3>Downloading Blocks</h3>
|
||||
<p>Every file is divided into multiple blocks, which are transmitted between peers. Each peer is a P2P client. Cluster Manager will check if the corresponding file exists in the local disk. If not, it will be downloaded into Cluster Manager from file server.</p>
|
||||

<h3>Downloading Blocks</h3>
|

<p>Every file is divided into multiple blocks, which are transmitted between peers. Each peer is a P2P client. Cluster Manager will check if the corresponding file exists in the local disk. If not, it will be downloaded into Cluster Manager from file server.</p>

<h2>Dubbo 与 Fescar 结合的例子</h2>
|
||||
<h3>Step 1: 安装数据库</h3>
|
||||
<ul>
|
||||
<li>要求: MySQL (InnoDB 存储引擎)。</li>
|
||||
</ul>
|
||||
<p><strong>提示:</strong> 事实上例子中3个微服务需要3个独立的数据库，但为了方便我们使用同一物理库并配置3个逻辑连接串。</p>
|
||||
<p>更改以下xml文件中的数据库url、username和password</p>
|
||||
<p>dubbo-account-service.xml
|
||||
dubbo-order-service.xml
|
||||
dubbo-storage-service.xml</p>
|
||||
<pre><code class="language-xml"> <span class="hljs-tag"><<span class="hljs-name">property</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"url"</span> <span class="hljs-attr">value</span>=<span class="hljs-string">"jdbc:mysql://x.x.x.x:3306/xxx"</span> /></span>
|
||||
<span class="hljs-tag"><<span class="hljs-name">property</span> <span class="hljs-attr">name</span>=<span class="hljs-string">"username"</span> <span class="hljs-attr">value</span>=<span class="hljs-string">"xxx"</span> /></span>

<h3>Step 2: 为 Fescar 创建 UNDO_LOG 表</h3>

|
||||
<h2>前提</h2>
|
||||
<ul>
|
||||
<li>基于支持本地 ACID 事务的关系型数据库。</li>
|
||||
<li>Java 应用，通过 JDBC 访问数据库。</li>
|
||||
</ul>
|
||||
<h2>整体机制</h2>
|
||||
<p>两阶段提交协议的演变：</p>
|
||||
<ul>
|
||||
<li>
|
||||
<p>一阶段：业务数据和回滚日志记录在同一个本地事务中提交，释放本地锁和连接资源。</p>
|
||||
</li>
|
||||
<li>
|
||||
<p>二阶段：</p>
|
||||
<ul>
|
||||
<li>提交异步化，非常快速地完成。</li>
|
||||
<li>回滚通过一阶段的回滚日志进行反向补偿。</li>
|
||||
</ul>
|
||||
</li>
|
||||
</ul>
|
||||
<h1>写隔离</h1>
|
||||
<ul>
|
||||
<li>一阶段本地事务提交前，需要确保先拿到 <strong>全局锁</strong> 。</li>
|
||||
<li>拿不到 <strong>全局锁</strong> ，不能提交本地事务。</li>
|
||||
<li>拿 <strong>全局锁</strong> 的尝试被限制在一定范围内，超出范围将放弃，并回滚本地事务，释放本地锁。</li>
|
||||
</ul>
|
||||
<p>以一个示例来说明：</p>
|
||||
<p>两个全局事务 tx1 和 tx2，分别对 a 表的 m 字段进行更新操作，m 的初始值 1000。</p>
|
||||
<p>tx1 先开始，开启本地事务，拿到本地锁，更新操作 m = 1000 - 100 = 900。本地事务提交前，先拿到该记录的 <strong>全局锁</strong> ，本地提交释放本地锁。
|
||||
tx2 后开始，开启本地事务，拿到本地锁，更新操作 m = 900 - 100 = 800。本地事务提交前，尝试拿该记录的 <strong>全局锁</strong> ，tx1 全局提交前，该记录的全局锁被 tx1 持有，tx2 需要重试等待 <strong>全局锁</strong> 。</p>
|
||||
<p><img src="https://upload-images.jianshu.io/upload_images/4420767-90b8bf0388953ee8.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240" alt="Write-Isolation: Commit"></p>
|
||||
<p>tx1 二阶段全局提交，释放 <strong>全局锁</strong> 。tx2 拿到 <strong>全局锁</strong> 提交本地事务。</p>
|
||||
<p><img src="https://upload-images.jianshu.io/upload_images/4420767-434090412a6a07b8.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240" alt="Write-Isolation: Rollback"></p>
|
||||
<p>如果 tx1 的二阶段全局回滚，则 tx1 需要重新获取该数据的本地锁，进行反向补偿的更新操作，实现分支的回滚。</p>
|
||||
<p>此时，如果 tx2 仍在等待该数据的 <strong>全局锁</strong>，同时持有本地锁，则 tx1 的分支回滚会失败。分支的回滚会一直重试，直到 tx2 的 <strong>全局锁</strong> 等锁超时，放弃 <strong>全局锁</strong> 并回滚本地事务释放本地锁，tx1 的分支回滚最终成功。</p>
|
||||
<p>因为整个过程 <strong>全局锁</strong> 在 tx1 结束前一直是被 tx1 持有的，所以不会发生 <strong>脏写</strong> 的问题。</p>
|
||||
<h1>读隔离</h1>
|
||||
<p>在数据库本地事务隔离级别 <strong>读已提交（Read Committed）</strong> 或以上的基础上，Fescar（AT 模式）的默认全局隔离级别是 <strong>读未提交（Read Uncommitted）</strong> 。</p>
|
||||
<p>如果应用在特定场景下，必需要求全局的 <strong>读已提交</strong> ，目前 Fescar 的方式是通过 SELECT FOR UPDATE 语句的代理。</p>
|
||||
<p><img src="https://upload-images.jianshu.io/upload_images/4420767-6236f075d02c5e34.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240" alt="Read Isolation: SELECT FOR UPDATE"></p>
|
||||
<p>SELECT FOR UPDATE 语句的执行会申请 <strong>全局锁</strong> ，如果 <strong>全局锁</strong> 被其他事务持有，则释放本地锁（回滚 SELECT FOR UPDATE 语句的本地执行）并重试。这个过程中，查询是被 block 住的，直到 <strong>全局锁</strong> 拿到，即读取的相关数据是 <strong>已提交</strong> 的，才返回。</p>
|
||||
<p>出于总体性能上的考虑，Fescar 目前的方案并没有对所有 SELECT 语句都进行代理，仅针对 FOR UPDATE 的 SELECT 语句。</p>
|
||||

|
||||
<h4>设计思路</h4>
|
||||
<ol>
|
||||
<li>Fescar作为一个被集成的数据一致性框架，Metrics模块将尽可能少的使用第三方依赖以降低发生冲突的风险；</li>
|
||||
<li>Metrics模块将竭力争取更高的度量性能和更低的资源开销，尽可能降低开启后带来的副作用；</li>
|
||||
<li>插件式——Metrics是否激活、数据如何发布，去取决于是否引入了对应的依赖，例如在TC Server中引入<code>fescar-metrics-prometheus</code>，则自动启用并将度量数据发布到<a href="https://github.com/prometheus">Prometheus</a>；</li>
|
||||
<li>不使用Spring，使用SPI(Service Provider Interface)加载扩展；</li>
|
||||
<li>初始仅发布核心Transaction相关指标，之后结合社区的需求，逐步完善运维方面的所有其他指标。</li>
|
||||
</ol>
|
||||
<h4>模块说明</h4>
|
||||
<p>由1个核心API模块<code>fescar-metrics-api</code>和N个对接实现模块如<code>fescar-metrics-prometheus</code>构成：</p>
|
||||
<ul>
|
||||
<li>fescar-metrics-api模块</li>
|
||||
</ul>
|
||||
<p>此模块是Metrics的核心，将作为Fescar基础架构的一部分被TC、TM和RM引用，它内部<strong>没有任何具体实现代码</strong>，仅包含接口定义，定义的内容包括：</p>
|
||||
<ol>
|
||||
<li>Meter类接口：<code>Gauge</code>、<code>Counter</code>、<code>Timer</code>...</li>
|
||||
<li>注册容器接口<code>Registry</code></li>
|
||||
<li>Measurement发布接口<code>Publisher</code></li>
|
||||
</ol>
|
||||
<blockquote>
|
||||
<p>提示：Metrics本身在开源领域也已有很多实现，例如</p>
|
||||
<ol>
|
||||
<li><a href="https://github.com/Netflix/spectator">Netflix-Spectator</a></li>
|
||||
<li><a href="https://github.com/dropwizard/metrics">Dropwizard-Metrics</a></li>
|
||||
<li><a href="https://github.com/dubbo/dubbo-metrics">Dubbo-Metrics</a></li>
|
||||
</ol>
|
||||
</blockquote>
|
||||
<blockquote>
|
||||
<p>它们有的轻而敏捷，有的重而强大，由于也是“实现”，因此不会纳入<code>fescar-metrics-api</code>中，避免实现绑定。</p>
|
||||
</blockquote>
|
||||
<ul>
|
||||
<li>fescar-metrics-prometheus模块</li>
|
||||
</ul>
|
||||
<p>这是我们默认提供的Metrics实现，不使用其它Metrics开源实现，并轻量级的实现了以下三个Meter：</p>
|
||||
<table>
|
||||
<thead>
|
||||
<tr>
|
||||
<th>Meter类型</th>
|
||||
<th>描述</th>
|
||||
</tr>
|
||||
</thead>
|
||||
<tbody>
|
||||
<tr>
|
||||
<td>Gauge</td>
|
||||
<td>单一最新值度量器</td>
|
||||
</tr>
|
||||
<tr>
|
||||
<td>Counter</td>
|
||||
<td>单一累加度量器，可增可减</td>
|
||||
</tr>
|
||||
<tr>
|
||||
<td>Summary</td>
|
||||
<td>多Measurement输出计数器，将输出<code>total</code>(合计)、<code>count</code>(计数)、<code>max</code>(最大)、<code>average</code>(合计/计数)和<code>tps</code>(合计/时间间隔)，无单位</td>
|
||||
</tr>
|
||||
<tr>
|
||||
<td>Timer</td>
|
||||
<td>多Measurement输出计时器，将输出<code>total</code>(合计)、<code>count</code>(计数)、<code>max</code>(最大)和<code>average</code>(合计/计数)，支持微秒为单位累计</td>
|
||||
</tr>
|
||||
</tbody>
|
||||
</table>
|
||||
<blockquote>
|
||||
<p>说明：</p>
|
||||
<ol>
|
||||
<li>未来可能增加更丰富复杂的度量器例如Histogram，这是一种可以本地统计聚合75th, 90th, 95th, 98th, 99th,99.9th...的度量器，适合某些场合，但需要更多内存。</li>
|
||||
<li>所有的计量器都将继承自Meter，所有的计量器执行measure()方法后，都将归一化的生成1或N个Measurement结果。</li>
|
||||
</ol>
|
||||
</blockquote>
|
||||
<p>它也会实现一个内存的Registry和PrometheusExporter，将度量数据同步给Prometheus。</p>
|
||||
<blockquote>
|
||||
<p>说明：不同的监控系统，采集度量数据的方式不尽相同，例如Zabbix支持用zabbix-agent推送，Prometheus则推荐使用prometheus-server<a href="https://prometheus.io/docs/practices/pushing/">拉取</a>的方式；同样数据交换协议也不同，因此往往需要逐一适配。</p>
|
||||
</blockquote>
|
||||
<h4>如何使用</h4>
|
||||
<h5>引入依赖</h5>
|
||||
<p>如果需要开启TC的Metrics，只需要在<code>fescar-server</code>的pom中增加：</p>
|
||||
<pre><code class="language-xml"><span class="hljs-tag"><<span class="hljs-name">dependencies</span>></span>
|
||||
<span class="hljs-tag"><<span class="hljs-name">dependency</span>></span>

|
||||
<span class="hljs-tag"></<span class="hljs-name">dependencies</span>></span>
|
||||
</code></pre>
|
||||
<p>之后启动TC，即可在<code>http://tc-server-ip:9898/metrics</code>上获取到Metrics的文本格式数据。</p>
|
||||
<blockquote>
|
||||
<p>提示：默认使用<code>9898</code>端口，Prometheus已登记的端口列表<a href="https://github.com/prometheus/prometheus/wiki/Default-port-allocations">在此</a>，如果想更换端口，可通过<code>metrics.exporter.prometheus.port</code>配置修改。</p>
|
||||
</blockquote>
|
||||
<h5>下载并启动Prometheus</h5>
|
||||
<p>下载完毕后，修改Prometheus的配置文件<code>prometheus.yml</code>，在<code>scrape_configs</code>中增加一项抓取Fescar的度量数据：</p>
|
||||
<pre><code class="language-yaml"><span class="hljs-attr">scrape_configs:</span>
|
||||
<span class="hljs-comment"># The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.</span>
|
||||
<span class="hljs-attr"> - job_name:</span> <span class="hljs-string">'prometheus'</span>
|
||||
|
||||
<span class="hljs-comment"># metrics_path defaults to '/metrics'</span>
|
||||
<span class="hljs-comment"># scheme defaults to 'http'.</span>
|
||||
|
||||
<span class="hljs-attr"> static_configs:</span>
|
||||
<span class="hljs-attr"> - targets:</span> <span class="hljs-string">['localhost:9090']</span>
|
||||
|
||||
<span class="hljs-attr"> - job_name:</span> <span class="hljs-string">'fescar'</span>
|
||||
|
||||
<span class="hljs-comment"># metrics_path defaults to '/metrics'</span>
|
||||
<span class="hljs-comment"># scheme defaults to 'http'.</span>
|
||||
|
||||
<span class="hljs-attr"> static_configs:</span>
|
||||
<span class="hljs-attr"> - targets:</span> <span class="hljs-string">['tc-server-ip:9898']</span>
|
||||
</code></pre>
|
||||
<h5>查看数据输出</h5>
|
||||
<p>推荐结合配置<a href="https://prometheus.io/docs/visualization/grafana/">Grafana</a>获得更好的查询效果，初期Fescar导出的Metrics包括：</p>
|
||||
<ul>
|
||||
<li>TC :</li>
|

</ul>
|
||||
<table>

<p>提示：fescar.transaction(role=tc,meter=summary,statistic=count,status=committed/rollback)和fescar.transaction(role=tc,meter=timer,statistic=count,status=committed/rollback)的值可能相同，但它们来源于两个不同的度量器。</p>
|
||||
</blockquote>
|
||||
<ul>
|
||||
<li>TM：</li>
|
||||
</ul>
|
||||
<p>稍后实现，包括诸如：
|
||||
fescar.transaction(role=tm,name={GlobalTransactionalName},meter=counter,status=active/committed/rollback) : 以GlobalTransactionalName为维度区分不同Transactional的状态。</p>
|
||||
<ul>
|
||||
<li>RM：</li>
|
||||
</ul>
|
||||
<p>稍后实现，包括诸如：
|
||||
fescar.transaction(role=rm,name={BranchTransactionalName},mode=at/mt,meter=counter,status=active/committed/rollback)：以BranchTransactionalName为维度以及AT/MT维度区分不同分支Transactional的状态。</p>
|
||||
<h4>如何扩展</h4>
|
||||
<p>如果有下面几种情况：</p>
|
||||
<ol>
|
||||
<li>您不是使用Prometheus作为运维监控系统，但希望能够将Fescar的Metrics数据集成进Dashboard中；</li>
|
||||
<li>您需要更复杂强大的度量器类型，这些度量器在其他Metrics实现库中已有，希望集成这些第三方依赖直接使用；</li>
|
||||
<li>您需要改变默认Metric的Measurement输出，例如在Timer中增加一个<code>min</code>或<code>sd</code>(方差)；</li>
|
||||
<li>...</li>
|
||||
</ol>
|
||||
<p>那么需要自行扩展Metrics的实现，请创建新的模块项目例如<code>fescar-metrics-xxxx</code>，之后：</p>
|
||||
<ul>
|
||||
<li>针对1：您需要实现新的Exporter；</li>
|
||||
<li>针对2：您可以改变默认Registry的实现，返回第三方的Meter计量器实现；</li>
|
||||
<li>针对3：您可以修改对应Meter的实现，包括<code>measure()</code>方法返回的Measurement列表。</li>
|
||||
</ul>

<p>回顾总览中的描述：一个分布式的全局事务，整体是 <strong>两阶段提交</strong> 的模型。全局事务是由若干分支事务组成的，分支事务要满足 <strong>两阶段提交</strong> 的模型要求，即需要每个分支事务都具备自己的：</p>

<ul>

<li>一阶段 prepare 行为</li>

<li>二阶段 commit 或 rollback 行为</li>

|

<p>根据两阶段行为模式的不同，我们将分支事务划分为 <strong>Automatic (Branch) Transaction Mode</strong> 和 <strong>TCC (Branch) Transaction Mode</strong>.</p>
|
||||
<p>AT 模式（<a href="">参考链接 TBD</a>）基于 <strong>支持本地 ACID 事务</strong> 的 <strong>关系型数据库</strong>：</p>
|
||||
<ul>
|
||||
<li>一阶段 prepare 行为：在本地事务中，一并提交业务数据更新和相应回滚日志记录。</li>
|
||||
<li>二阶段 commit 行为：马上成功结束，<strong>自动</strong> 异步批量清理回滚日志。</li>
|
||||
<li>二阶段 rollback 行为：通过回滚日志，<strong>自动</strong> 生成补偿操作，完成数据回滚。</li>
|
||||
</ul>
|
||||
<p>相应的，TCC 模式，不依赖于底层数据资源的事务支持：</p>
|
||||
<ul>
|
||||
<li>一阶段 prepare 行为：调用 <strong>自定义</strong> 的 prepare 逻辑。</li>
|
||||
<li>二阶段 commit 行为：调用 <strong>自定义</strong> 的 commit 逻辑。</li>
|
||||
<li>二阶段 rollback 行为：调用 <strong>自定义</strong> 的 rollback 逻辑。</li>
|

</ul>
|

<p>所谓 TCC 模式，是指支持把 <strong>自定义</strong> 的分支事务纳入到全局事务的管理中。</p>
