> Good point on ensuring pushdown for `GROUP BY filename()` / `ORDER BY filename()`. May need the rewrite early in planning so downstream operators see the resolved column. I'll reach out if that gets tricky. Oh it will! Andrew and I are working on exactly this problem but for struct field access. I’d say let’s not duplicate effort in this regard. So maybe like you say start with “what if this expression is in a projection right above the ParquetSource” and then we can work on making sure it gets there from the GroupBy. Some background: https://github.com/apache/datafusion/pull/19538. I need to do work on this PR but maybe I can also tag you for review on related work? -- This is an automated message from the Apache Git Service.
