Kevin Risden commented on SOLR-8593:
------------------------------------
[~joel.bernstein] & [~julianhyde] - I tried to set user.locale=tr for the
Calcite and Avatica proper tests and couldn't get it to fail. I haven't been
able to isolate the issue. The few things I tried from the Calcite repo:
{code}
MAVEN_OPTS="$MAVEN_OPTS -Duser.locale=tr" mvn clean test
Add -Duser.locale=tr to the surefire argLinein pom.xml
{code}
Neither of the above made tests in either Calcite or Avatica fail. Not sure
where to go from here.
> Integrate Apache Calcite into the SQLHandler

> Project: Solr
> Issue Type: Improvement
> Components: Parallel SQL
> Reporter: 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.
