-------------------------------------
@Thomas - I think the approach to manually split jobs with a pubsub is an
option. It could be interesting to add some tooling for that.

> Key: FLINK-4256
> URL: https://issues.apache.org/jira/browse/FLINK-4256
> Project: Flink

> Components: Runtime / Coordination
> Affects Versions: 1.1.0
> Reporter: Stephan Ewen

>
> When a task fails during execution, Flink currently resets the entire
> execution graph and triggers complete re-execution from the last completed
> checkpoint. This is more expensive than just re-executing the failed tasks.
> In many cases, more fine-grained recovery is possible.
> The full description and design is in the corresponding FLIP.
