---------------------------------------------------------------
Very excited about this patch. After a day of review I think understand how
this comes together. Next step is for me to get it running. Initial run of the
test cases fail, probably due to the classpath issue that [~risdenk] mentions.
I'll work on getting it running as the next step and compare the feature set
with the current release.

> 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
>
> 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.
