[GitHub] [arrow-datafusion] alamb commented on pull request #1378: Metadata is kept in projections for non-derived columns

   Thanks again @hntd187  -- I reviewed some other areas of the code, and I found several places where a projection is done on a RecordBatch and Schemas other than the ProjectionExec. I filed https://github.com/apache/arrow-rs/issues/1014 to move this logic into arrow-rs and I'll file a follow on ticket in DataFusion to refactor projection uses to a consolidated implementation
