Hey Calcite! Was hoping to obtain contributor permission in JIRA? I've done some minor hacking with Calcite and contributed a (very minor) fix a bit back <https://issues.apache.org/jira/browse/CALCITE-4972> but looking to maybe attempt some larger issues in the coming weeks. CALCITE-4362 <https://issues.apache.org/jira/browse/CALCITE-4362> was one candidate.
My JIRA username is: mgthesecond Thanks! Mark
