Guowei Ma commented on FLINK-15670:
-----------------------------------
>>>I am wondering how do we expose this feature to the users?
Maybe we could do something automatically when generating the StreamGraph or
JobGraph.
For example if `_blockingConnectionsBetweenChains_ ` is true we could add the
Kafka source and Kafka sink automatically between the two shuffle operators
automatically. The topic could use the operator's uid.
> Provide a Kafka Source/Sink pair that aligns Kafka's Partitions and Flink's
> KeyGroups

> Components: API / DataStream, Connectors / Kafka
> Reporter: Stephan Ewen
> Priority: Major
> Labels: usability
> Fix For: 1.11.0

>
> This Source/Sink pair would serve two purposes:
> 1. You can read topics that are already partitioned by key and process them
> without partitioning them again (avoid shuffles)
> 2. You can use this to shuffle through Kafka, thereby decomposing the job
> into smaller jobs and independent pipelined regions that fail over
> independently.
