> I'm also looking at whether the issue arises somewhere in TypeCoercion analyzer Ok, looks like `TypeCoercion` works as intended, and it seems like `SimplifyExpressions` is the culprit behind the particular problem in delta-rs. From the new issue https://github.com/apache/datafusion/issues/13481 I've opened: > Basically TypeCoercion injects the CAST, while SimplifyExpressions omits it. Consequently OptimizeProjections folds the two projections, but the schema is computed from the outermost projection expressions, which now lack the proper type info (i.e. the non-standard list item field names). -- This is an automated message from the Apache Git Service.
