David Smiley commented on SOLR-8593:
------------------------------------
Thanks Julian. I tried removing both and tests don't pass; both lead to –
ClassNotFoundException. I won't pursue this further. I'm most surprised by
the ESRI dependency because ST_Distance would take some integration with Solr
for it (I think) and none has been done. I'll share a snippet of the
ClassNotFoundException stack trace:

> Integrate Apache Calcite into the SQLHandler
> --------------------------------------------
>
> Key: SOLR-8593
> URL: https://issues.apache.org/jira/browse/SOLR-8593
> Project: Solr
> Issue Type: Improvement
> Components: Parallel SQL
> Reporter: Joel Bernstein
> Assignee: Joel Bernstein
> Priority: Major
> Fix For: 6.5, 7.0
>
> Attachments: SOLR-8593.patch, 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.
