> This is similar
> [FLINK-12575|https://issues.apache.org/jira/browse/FLINK-12575], we could
> implement {{satisfyTraits}} method for stream nodes to remove redundant
> shuffle. This could add more possibilities that more operators can be merged
> into multiple input operator.
> Different batch, stream operators require the shuffle keys and the state keys
> must be exactly the same, otherwise the state may be not correct.
> We only support a few operators in this issue, such as Join and regular
> Aggregate. Other operators will be supported in the future.
