> Key: FLINK-31654
> URL: https://issues.apache.org/jira/browse/FLINK-31654
> Project: Flink
> Issue Type: Bug
> Components: API / DataStream
> Affects Versions: 1.17.0, 1.14.6, 1.16.1, 1.15.4
> Reporter: Jiangjie Qin
> Assignee: Jiangjie Qin
> Priority: Major
> Fix For: 1.18.0, 1.17.1
>
>
> Currently {{DataStreamUtils.reinterpretAsKeyedStream()}} does not work well
> with batch jobs. There are two issues:
> # The input to the downstream operator will not be sorted. So users need to
> sort the records by themselves.
> # The result {{KeyedStream}} will still override the chaining strategy of
> the downstream operator to {{HEAD.}} This breaks the operator chain and
> defeats the purpose of reinterpreting the stream instead of calling {{keyBy.}}
> This ticket tends to address the second issue.
