The new algorithm assumes there is only one tag per request,
so queues are partitioned by tag. This is a more efficient approach than
the old algorithm.
* throttle the cluster when blob workers fall behind
* do not throttle on blob workers if they are not enabled
* remove an unnecessary actor
* fixed a compile error
* fetch blob worker metrics at the same interval as the rate is updated, avoid fetching the complete blob worker list too frequently
* fixed another compilation bug
* added a 5 second delay before bw throttling to prevent false positives caused by the 100e6 version jump during recovery. Lower the throttling thresholds to react much quicker to bw lag.
* fixed a number of problems
* changed the minBlobVersionRequest to look at storage server versions since this will be a lot more efficient
* fix: do not let desired go backwards
* fix: track the version of notAtLatest changefeeds for throttling
* ratekeeper now throttled blob workers by estimating the transaction per second throughput of the blob workers
* added metrics for blob worker change feeds
* added a knob to disable bw throttling
* fixed the transaction options in blob manager
Currently GRV is reporting proxy_memory_limit_exceeded error which has
error message claiming Commit proxy failing. This split should remove
such confusion.
Clients now poll the proxy for the latest global config for a specific
version. The proxy now periodically requests the latest global
configuration data and stores it in memory, enabling it to respond
immediately to clients with the appropriate version.
Clients should avoid reading system keys unless authorized. Under global
config, each client reads from the system keyspace to check for new
global config keys. This commit moves these reads to a server role (the
GRV proxies) and sends the results back to GlobalConfig for an in-memory
update.
* proof of concept
* use code-probe instead of test
* code probe working on gcc
* code probe implemented
* renamed TestProbe to CodeProbe
* fixed refactoring typo
* support filtered output
* print probes at end of simulation
* fix missed probes print
* fix deduplication
* Fix refactoring issues
* revert bad refactor
* make sure file paths are relative
* fix more wrong refactor changes
