Specifies the amount of time a backup or DR needs to be stale before ``cleanup`` will remove mutations for it. By default this is set to one hour.

Release Notes
#############
6.1.13
======
* Loading a 6.1 or newer ``fdb_c`` library as a secondary client using the multi-version client could lead to an infinite recursion when run with API versions older than 610. `(PR #2169) <https://github.com/apple/foundationdb/pull/2169>`_
* Using C API functions that were removed in 6.1 when using API version 610 or above now results in a compilation error. `(PR #2169) <https://github.com/apple/foundationdb/pull/2169>`_
* ``fdbrestore`` commands other than ``start`` required a default cluster file to be found but did not actually use it. `(PR #1912) <https://github.com/apple/foundationdb/pull/1912>`_.

* Log routers will prefer to peek from satellites at ``log_version >= 4``. `(PR #1795) <https://github.com/apple/foundationdb/pull/1795>`_.
* In clusters using a region configuration, clients will read from the remote region if all of the servers in the primary region are overloaded. [6.2.3] `(PR #2019) <https://github.com/apple/foundationdb/pull/2019>`_.
* Significantly improved the rate at which the transaction logs in a remote region can pull data from the primary region. [6.2.4] `(PR #2101) <https://github.com/apple/foundationdb/pull/2101>`_.
* Raised the data distribution priority of splitting shards because delaying splits can cause hot write shards. [6.2.6] `(PR #2234) <https://github.com/apple/foundationdb/pull/2234>`_.

* Clients no longer prefer reading from servers with the same zone ID, because it could create hot shards. [6.2.3] `(PR #2019) <https://github.com/apple/foundationdb/pull/2019>`_.
* Data distribution could fail to start if any storage servers had misconfigured locality information. This problem could persist even after the offending storage servers were removed or fixed. [6.2.5] `(PR #2110) <https://github.com/apple/foundationdb/pull/2110>`_.
* Data distribution was running at too high of a priority, which sometimes caused other roles on the same process to stall. [6.2.5] `(PR #2170) <https://github.com/apple/foundationdb/pull/2170>`_.

* Coordinator changes could fail to complete if the database wasn't allowing any transactions to start. [6.2.6] `(PR #2191) <https://github.com/apple/foundationdb/pull/2191>`_
* Status would report incorrect fault tolerance metrics when a remote region was configured and the primary region lost a storage replica. [6.2.6] `(PR #2230) <https://github.com/apple/foundationdb/pull/2230>`_
* The cluster would not change to a new set of satellite transaction logs when they become available in a better satellite location. [6.2.6] `(PR #2241) <https://github.com/apple/foundationdb/pull/2241>`_.
* The existence of ``proxy`` or ``resolver`` class processes prevented ``stateless`` class processes from being recruited as proxies or resolvers. [6.2.6] `(PR #2241) <https://github.com/apple/foundationdb/pull/2241>`_.
* Committing transactions larger than 1 MB could cause the proxy to stall for up to a second. [6.2.6] `(PR #2250) <https://github.com/apple/foundationdb/pull/2250>`_.
* The cluster controller could become saturated in clusters with large numbers of connected clients using TLS. [6.2.6] `(PR #2252) <https://github.com/apple/foundationdb/pull/2252>`_.
* Backup and DR would not share a mutation stream if they were started on different versions of FoundationDB. Either backup or DR must be restarted to resolve this issue. [6.2.6] `(PR #2202) <https://github.com/apple/foundationdb/pull/2202>`_.
Status
------

* Add ``coordinator`` to the list of roles that can be reported for a process. [6.2.3] `(PR #2006) <https://github.com/apple/foundationdb/pull/2006>`_.
* Added ``worst_durability_lag_storage_server`` and ``limiting_durability_lag_storage_server`` to the ``cluster.qos`` section, each with subfields ``versions`` and ``seconds``. These report the durability lag values being used by ratekeeper to potentially limit the transaction rate. [6.2.3] `(PR #2003) <https://github.com/apple/foundationdb/pull/2003>`_.
* Added ``worst_data_lag_storage_server`` and ``limiting_data_lag_storage_server`` to the ``cluster.qos`` section, each with subfields ``versions`` and ``seconds``. These are meant to replace ``worst_version_lag_storage_server`` and ``limiting_version_lag_storage_server``, which are now deprecated. [6.2.3] `(PR #2003) <https://github.com/apple/foundationdb/pull/2003>`_.
* Added ``system_kv_size_bytes`` to the ``cluster.data`` section to record the size of the system keyspace. [6.2.5] `(PR #2170) <https://github.com/apple/foundationdb/pull/2170>`_.
Bindings
--------
@ -78,6 +90,12 @@ Bindings
* Added a transaction option to control the whether ``get_addresses_for_key`` includes a port in the address. This will be deprecated in api version 700, and addresses will include ports by default. [6.2.4] `(PR #2060) <https://github.com/apple/foundationdb/pull/2060>`_.
* Python: ``Versionstamp`` comparisons didn't work in Python 3. [6.2.4] `(PR #2089) <https://github.com/apple/foundationdb/pull/2089>`_.
Features
--------
* Added the ``cleanup`` command to ``fdbbackup`` which can be used to remove orphaned backups or DRs. [6.2.5] `(PR #2170) <https://github.com/apple/foundationdb/pull/2170>`_.
* Added the ability to configure ``satellite_logs`` by satellite location. This will overwrite the region configure of ``satellite_logs`` if both are present. [6.2.6] `(PR #2241) <https://github.com/apple/foundationdb/pull/2241>`_.
Other Changes
-------------

* The cluster controller would saturate its CPU for a few seconds when sending configuration information to all of the worker processes. [6.2.4] `(PR #2086) <https://github.com/apple/foundationdb/pull/2086>`_.
* The data distributor would build all possible team combinations if it was tracking an unhealthy server with less than 10 teams. [6.2.4] `(PR #2099) <https://github.com/apple/foundationdb/pull/2099>`_.
