…artial update (#38487) If a rowset is produced by compaction before the commit phase of the partial update load and is not included in `txn_info->rowset_ids`, we can skip the alignment process of that rowset because data remains the same before and after compaction. But we still need to calculate the the delete bitmap for that rowset.
