> Issue Type: Improvement
> Components: Streaming
> Reporter: Gyula Fora
> Assignee: Gyula Fora

> Currently, all stream operators are automatically assigned to the same task
> sharing group, and the user has no control over this setting. We should add a
> way to manually affect the way operators are allocated to task manager slots.
