             Summary: Activate bloom filter in RocksDB State Backend via Flink configuration
                 Key: FLINK-21336
                 URL: https://issues.apache.org/jira/browse/FLINK-21336
             Project: Flink
          Issue Type: Improvement
            Reporter: Jun Qin
            Assignee: Jun Qin


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.
