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

             Summary: Deprecate ValueStateDescriptor constructors with default value
                 Key: FLINK-5155
                 URL: https://issues.apache.org/jira/browse/FLINK-5155
             Project: Flink
          Issue Type: Improvement
          Components: Streaming
            Reporter: Aljoscha Krettek


Having the default value in the descriptor is problematic with some serialisers and we don't lose a feature because users can always check for the null value and initialise with their own default value if necessary. Right now, we're always forcing people to specify a default value even though they don't need one.
