             Summary: Forward RocksDB memory metrics to Flink metrics reporter 
                 Key: FLINK-10423
                 URL: https://issues.apache.org/jira/browse/FLINK-10423
             Project: Flink
          Issue Type: New Feature
          Components: Metrics, State Backends, Checkpointing
            Reporter: Seth Wiesman
            Assignee: Seth Wiesman


RocksDB contains a number of metrics at the column family level about current memory usage, open memtables,  etc that would be useful to users wishing greater insight what rocksdb is doing. This work is inspired heavily by the comments on this rocksdb issue thread (https://github.com/facebook/rocksdb/issues/3216#issuecomment-348779233)
