Yun Tang commented on FLINK-15065:
----------------------------------
[~liuyufei] thanks for your careful check. Actually, we have already corrected
the writebuffer size to {{64MB}} in FLINK-14846 and
[https://github.com/facebook/rocksdb/pull/5670]. Can't believe official RocksDB
javadoc still has so many errors. I will go through all the settings and create
one PR to fix Flink's doc and another one to fix RocksDB's java doc.

> Project: Flink
> Issue Type: Bug
> Components: Documentation

> Reporter: YufeiLiu
> Priority: Major
>
> [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
