---------------------------------

             Summary: RocksDB statebackend creates empty dbs for stateless operators
                 Key: FLINK-3841
                 URL: https://issues.apache.org/jira/browse/FLINK-3841
             Project: Flink
          Issue Type: Bug
          Components: state backends
            Reporter: Gyula Fora
            Priority: Minor


Even though they are not checkpointed there is always an open RocksDB database for all operators if the Rocks backend is set. I wonder if it would make sense to lazy initialize the dbs instead of doing it in the initializeForJob method.
