Yun Tang commented on FLINK-14482:
----------------------------------
At first, we plan to bump the base rocksDB version from 5.17.2 to 5.18.3 to
support write buffer manager feature. However, when we test with flink's
[benchmark|https://github.com/dataArtisans/flink-benchmarks], and we found all
test cases behave with performance regression from 1% ~ 9%, more details could
refer to rocksDB's [issue-5774|https://github.com/facebook/rocksdb/issues/5774].
Until now, even we could reproduce this with RocksDB built-in db_bench, there
still no exact answer for this problem.
