> [RocksDB Configurable Options 
> |https://ci.apache.org/projects/flink/flink-docs-release-1.9/ops/config.html#rocksdb-configurable-options]
> As description, rocksdb has default options:
> state.backend.rocksdb.compaction.level.max-size-level-base: 10MB
> state.backend.rocksdb.compaction.level.target-file-size-base: 4MB
> state.backend.rocksdb.writebuffer.size: 2MB
> But I found the actual options is: 
> state.backend.rocksdb.compaction.level.max-size-level-base: 256MB
> state.backend.rocksdb.compaction.level.target-file-size-base: 64MB
> state.backend.rocksdb.writebuffer.size: 64MB
> maybe the description is wrong
