             Summary: Replace all ByteArrayOutputStream and DataOutputStream use in State Backends by DataOutputSerializer
                 Key: FLINK-3387
                 URL: https://issues.apache.org/jira/browse/FLINK-3387
             Project: Flink
          Issue Type: Bug
          Components: state backends
    Affects Versions: 1.0.0
            Reporter: Stephan Ewen


Currently, the {{byte[]}} to object conversion and vice versa is always done by creating new byte array streams and Data Input/Output streams. That is pretty wasteful, we can optimize this with Flink's own classes:
  - {{DataInputSerializer}}
  - {{DataOutputSerializer}}
