Change subject: [compaction] Skip memory allocation for ancient undo deltas ...................................................................... [compaction] Skip memory allocation for ancient undo deltas Currently, while applying REDO mutations to base row and create corresponding UNDO deltas for each REDO mutation, we don't check whether any mutation is ancient that is anyway going to be ignored and removed from list of UNDO deltas in later stage of processing. This change checks each REDO mutation beforehand and doesn't allocate any memory if found ancient. This avoids unnecessary memory usage.
