> 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
> Assignee: Aljoscha Krettek
> Fix For: 1.2.0
>
>
> 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.
> Of course, we should add constructors without a default value.
