Yes. But that's the problem of your use cases, right? If you need to wait for the sink to be completed, it is not a terminating operator anymore.

Thank you very much for your answer.

I have a question regarding your first paragraph:
" it requires that a sink participates in the pipeline. So it is not located
as a "leaf" operator but location somewhere in the middle."

Isn't Sink a terminating operator? So as far as I know Sinks cannot be in
the middle of stream chain.


I will appreciate other comments as well.

Thanks,
Krzysztof
