--------------------------------------------------------------
It doesn't look like we're going to get this in for Solr 6.4. So, I'm currently
planning to take the HavingStream from this branch and commit it with SOLR-8530
for Solr 6.4
This is going to cause merge conflicts between jira/solr-8593 and master. As
soon as the Calcite release is cut I'll begin the work to merge jira/solr-8593
to master and work out the conflicts. So Calcite will be in master at the very
beginning of the dev cycle for Solr 6.5. Then we can work with the Calcite code
in master and perform the backport to branch_6x when ready.

> Integrate Apache Calcite into the SQLHandler
> --------------------------------------------
>
> Key: SOLR-8593
> URL: https://issues.apache.org/jira/browse/SOLR-8593
> Project: Solr
> Issue Type: Improvement
> Reporter: Joel Bernstein
> Assignee: Joel Bernstein
> Attachments: SOLR-8593.patch, SOLR-8593.patch
>
>
> The Presto SQL Parser was perfect for phase one of the SQLHandler. It was
> nicely split off from the larger Presto project and it did everything that
> was needed for the initial implementation.
> Phase two of the SQL work though will require an optimizer. Here is where
> Apache Calcite comes into play. It has a battle tested cost based optimizer
> and has been integrated into Apache Drill and Hive.
> This work can begin in trunk following the 6.0 release. The final query plans
> will continue to be translated to Streaming API objects (TupleStreams), so
> continued work on the JDBC driver should plug in nicely with the Calcite work.
