Subject [jira] [Commented] (APEXMALHAR-1818) Integrate Calcite to support SQL
Date Fri, 23 Sep 2016 00:26:20 GMT

Julian Hyde commented on APEXMALHAR-1818:
-----------------------------------------

[~chinmay], I watched the demo video and took a look at your code, and it all looks fine.
I suspect that you could get semantic stuff like view substitution with a low amount of effort.

I know you're planning inner join (I presume stream-to-stream join?). It will be interesting
when you also support streaming GROUP BY and streaming windowed aggregate functions.

I started work on a streaming TCK in Calcite; see CALCITE-1114. You could potentially use
that to verify that your implementation of streaming SQL is correct.

> Once we have ability to generate a subdag, we should take a look at integrating Calcite
into Apex. The operator that enables populate DAG, should use Calcite to generate the DAG,
given a SQL query.
