Description

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.
