             Summary: Avoid using reflection to get filter when partition 
filter is enabled
                 Key: FLINK-23798
                 URL: https://issues.apache.org/jira/browse/FLINK-23798
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / State Backends
            Reporter: Yun Tang
             Fix For: 1.14.0


FLINK-20496 introduce partitioned index & filter to Flink. However, RocksDB 
only support new full format of filter in this feature, and we need to replace 
previous filter if user enabled. [Previous implementation use reflection to get 
the 
filter|https://github.com/apache/flink/blob/7ff4cbdc25aa971dccaf5ce02aaf46dc1e7345cc/flink-state-backends/flink-statebackend-rocksdb/src/main/java/org/apache/flink/contrib/streaming/state/RocksDBResourceContainer.java#L251-L258]
 and we could use API to get that after upgrading to newer version.
