>                 URL: https://issues.apache.org/jira/browse/FLINK-19494
>             Project: Flink
>          Issue Type: Improvement
>          Components: API / DataStream
>            Reporter: Stephan Ewen
>            Assignee: Nicholas Jiang
>            Priority: Major
>              Labels: pull-request-available
>             Fix For: 1.12.0
>
>
> The utility method {{StreamExecutionEnvironment.generateSequence(()}} should instantiate the new {{NumberSequenceSource}} rather than the existing {{StatefulSequenceSource}}.
> We should also deprecate the {{StatefulSequenceSource}} as part of this change, because
>   - it is based on the legacy source API
>   - it is not scalable, because it materializes the sequence
