Worklog Id: (was: 179477)
Time Spent: 20m (was: 10m)
> Use Flink's redistribute for reshuffle.
> ---------------------------------------
>
> Key: BEAM-6294
> URL: https://issues.apache.org/jira/browse/BEAM-6294
> Project: Beam
> Issue Type: New Feature
> Components: runner-flink, sdk-py-core
> Reporter: Robert Bradshaw
> Assignee: Robert Bradshaw
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Python needs to publish the URN over the FnAPI which is pretty easy, but
> Flink also needs to ensure that the composite structure does not get fused.
> Unlike with GBK, we can't assume all runners implement this as a primitive.
