------------------------------------------
Just confirming here. 👌
> Adjust "StreamExecutionEnvironment.generateSequence()" to new API Sources
> -------------------------------------------------------------------------
>
> Key: FLINK-19494
> URL: https://issues.apache.org/jira/browse/FLINK-19494
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Reporter: Stephan Ewen
> Priority: Major
> 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
