-----------------------------------------------
Hi [~julianhyde],
Thanks for looking at the code. I've created a PR for the same now:
https://github.com/apache/apex-malhar/pull/432
Please provide any feedback there if you have any.
The PR contains implementation for inner join having non-empty equi-join
condition. And yes its a stream-to-stream join.
As you rightly said, my next work on integration will be provide support for
group by and windowed aggregation functions.
I'll take a look at CALCITE-1114 to see if that helps in testing.
Also, is there any document that you can share related to semantic like view
substitutions that I can look at?
Hi [~thw],
Please share your feedback as well on the PR when you get chance.
