>There might be some ways to pass partition count to upstream, and easy way
to do might be adding method to DataSourcesProvider. What I'm considering is
that we're now only thinking about partition count, but Calcite supports table
statistics which contains estimated row count (not available for streaming
env., partitioning attributes, etc.). Is passing partition count exhaustive?
I'm not sure.
Perhaps I can give you some suggestions when I have a deeper understanding
in Calcite. But now I think we can address STORM-2147 using a simple way before
we get a better one.
>As this is on top of STORM-1446 which needs understanding of Calcite,
learning Calcite is more important for you to work on further works for Storm
SQL, especially Storm SQL lacks reviewers to go forward. So if you haven't had
time, please take your time to get it.
Thanks for your advice, yes, learning Calcite is in my plan.
