Problem Summary: Later, we will support parallel compaction, which means one compaction sub task only handles somes rows of the input rowsets. Now, Row ID conversion allocated a dense destination entry for every source row, which wastes memory when a compaction reads only sparse source ranges. Add an opt-in lazy chunked mode that allocates mappings only for touched rows.
