Subject [jira] [Comment Edited] (SOLR-8593) Integrate Apache Calcite into the SQLHandler
Date Mon, 06 Feb 2017 17:59:42 GMT

--------------------------------------------------------------

After adjusting the SolrFilterRule to allow filters on expressions, the having filter now
shows up above the SolrAggregate:

SolrFilter
SolrAggregate
SolrFilter
SolrTableScan

The first SolrFilter listed is the Having clause and second SolrFilter is the WHERE clause.

The next step is to recognize the different types of filters and build a HavingStream for
the having filter. I'll be working on plugging this in.

>    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.
