Aljoscha Krettek updated FLINK-19083:
-------------------------------------
Description:
{{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
- Has bugs: see FLINK-5031
- 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.
> Remove deprecated DataStream#split
