> RocksDB has an option to optimize Bloom Filter that minimizes internal memory fragmentation.
> The feature's been production ready since v6.22.0. According to RocksDB release note, v9.2.0 and above, this flag is enabled by default. It is said to reduce memory footprint by 10%. https://sourcegraph.com/github.com/facebook/rocksdb/-/blob/HISTORY.md#behavior-changes-9
> https://github.com/facebook/rocksdb/blob/main/java/src/main/java/org/rocksdb/BlockBasedTableConfig.java#L509
> We should either bump RocksDB version or enable this feature flag in our current version.
