> 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
