Hello Calcite community, Taking the opportunity here to do an intro as a first time prospective contributor! I'm Mark, a data engineer from the northeastern US.
I've been a user of Calcite's query parsing and relational algebra generation capabilities for several months but only just recently started to attempt hacking on Calcite itself. Following up on a discussion in the mailing list I filed CALCITE-4972 <https://issues.apache.org/jira/browse/CALCITE-4972>, and subsequently attempted a patch for it <https://github.com/apache/calcite/pull/2683> as a potentially newbie-friendly task. Reviews are much appreciated! The internals of the SqlValidator are quite new to me. My JIRA username is *mgthesecond* Thanks, Mark
