[jira] [Closed] (FLINK-23812) Support configuration of the RocksDB logging via configuration

["Nico Kruber (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/FLINK-23812?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nico Kruber closed FLINK-23812.
-------------------------------
    Fix Version/s: 1.14.0
     Release Note: With RocksDB bumped to 6.20.3 (FLINK-14482), you can now also configure a rolling info logging strategy by configuring it accordingly via newly added state.backend.rocksdb.log.* settings. This can be helpful for debugging RocksDB (performance) issues in containerized environments where the local data dir is volatile but the logs should be retained on a separate volume mount.
       Resolution: Fixed

Merged on master via a86f8a5f59fbc49fb62feeda26c159a716631752

> Since FLINK-14482 has been merged now, we should also allow users to configure more than just the log level (FLINK-20911) but also the following parameters so that they can safely enable RocksDB logging again (once disabled by default in FLINK-15068) by using a rolling logger, for example:
> - max log file size via {{state.backend.rocksdb.log.max-file-size}}
> - logging files to keep via {{state.backend.rocksdb.log.file-num}}
> - log directory {{state.backend.rocksdb.log.dir}}, e.g. to put these logs onto a (separate) volume that may not be local and is retained after container shutdown for debugging purposes
