> When introduce {{RocksDBConfigurableOptions}}, the default writer buffer size is referenced from RocksDB's javadoc. Unfortunately, RocksDB's official javadoc was described incorrectly as {{4MB}} for a long time until I create a [PR|https://github.com/facebook/rocksdb/pull/5670] to correct it. This also leads [our description|https://ci.apache.org/projects/flink/flink-docs-stable/ops/config.html#state-backend-rocksdb-writebuffer-size] of default write-buffer size not correct, we should fix this to avoid to mislead users.
