Activate bloom filter in RocksDB State Backend via Flink configuration

    XMLWordPrintableJSON

Details

    Description

      Activating bloom filter in the RocksDB state backend improves read performance. Currently activating bloom filter can only be done by implementing a custom ConfigurableRocksDBOptionsFactory. I think we should provide an option to activate bloom filter via Flink configuration.
