------------------------------
Summary: Support to modify RocksDB LOG level
Key: FLINK-20911
URL: https://issues.apache.org/jira/browse/FLINK-20911
Project: Flink
Issue Type: Improvement
Components: Runtime / State Backends
Affects Versions: 1.13.0, 1.12.1
Reporter: fanrui
The LOG level of RocksDB is hard-coded and is always HEADER_LEVEL. Sometimes
RocksDB becomes unstable due to unreasonable parameter settings, and the
problem can be reproduced after restart. At this time, you may need to check
some LOGs to troubleshoot.
It may be better if the LOG level of RocksDB can be adjusted. Of course, the
default LOG level is still HEADER_LEVEL. When dealing with problems, it can be
adjusted to DEBUG_LEVEL.
