Note on `RowType::WordAligned`, which is used as the grouping state for hash aggregation: Since the varlena field would expand its width as new updates come in, fields after varlena should be moved accordingly to make them readable/updatable after a varlena update. We may consider an "out of place" store for these varlenas for `RowType::WordAligned`, to relieve the repeated need for moving/copying fixed-sized fields stored after valena fields. And put them in place when the update is finalized later. -- This is an automated message from the Apache Git Service.
