Dear Drillers, I'm trying to implement support for CROSS JOIN syntax in Apache Drill. But after long investigation I finally run out of ideas and don't see proper way how this could be implemented without changes to Calcite. I'm new to Drill and Calcite and I would appreciate any help. Please, take a look at my comment under the issue https://issues.apache.org/jira/browse/DRILL-786.
Thank you in advance, Igor Guzenko
