-------------------------------------
Fix Version/s: (was: 2.0.0)
1.12.0
> Remove deprecated DataStream#split
> ----------------------------------
>
> Key: FLINK-19083
> URL: https://issues.apache.org/jira/browse/FLINK-19083
> Project: Flink
> Issue Type: Sub-task
> Components: API / DataStream
> Reporter: Dawid Wysakowicz
> Priority: Major
> Fix For: 1.12.0
>
>
> {{DataStream#split()}} has been deprecated in favour of using Side Outputs
> because:
> - It is less performant, {{split()}} creates and checks against {{Strings}}
> for the splitting logic.
> - {{split()}} was and is buggy : see FLINK-5031 and FLINK-11084, for example
> - The semantics of consecutive splits are not very clear in general.
> - Side outputs are more general and everything that could be done using
> {{split()}} can be achieved with side outputs with strictly better
> performance.
