> Configurable little parallelism in Gelly drivers
> ------------------------------------------------
>
> Key: FLINK-4571
> URL: https://issues.apache.org/jira/browse/FLINK-4571
> Project: Flink
> Issue Type: Improvement
> Components: Gelly
> Affects Versions: 1.2.0
> Reporter: Greg Hogan
> Assignee: Greg Hogan
> Priority: Minor
>
> Several Gelly library implementations support a configurable "little
> parallelism" which is important when scaling to large data sets. These
> algorithms include operators at the beginning and end which process data on
> the order of the original DataSet, as well as middle operators that exchange
> 100s or 1000s more data. The "little parallelism" should be configurable in
> the appropriate Gelly drivers in the flink-gelly-examples module.
