> Make the StatefulSequenceSource scalable.
> -----------------------------------------
>
> Key: FLINK-6215
> URL: https://issues.apache.org/jira/browse/FLINK-6215
> Project: Flink
> Issue Type: Bug
> Components: DataStream API
> Affects Versions: 1.3.0
> Reporter: Kostas Kloudas
> Assignee: Kostas Kloudas
> Fix For: 1.4.0, 1.3.3
>
>
> Currently the {{StatefulSequenceSource}} instantiates all the elements to
> emit first and keeps them in memory. This is not scalable as for large
> sequences of elements this can lead to out of memory exceptions.
> To solve this, we can pre-partition the sequence of elements based on the
> {{maxParallelism}} parameter, and just keep state (to checkpoint) per such
> partition.
