> We could have a separate section in the docs about performance tuning (maybe separately
for batch and streaming jobs).
> It could include for example:
> - object reuse
> - serializer issues
> - semantic annotations
> - optimizer hints
> - sorter code generation (Flink-5734)
> See [~fhueske]'s suggestion here:
