Purpose
Add
clustering.incremental.modeoption with two values:global-sort(default): existing behavior, global range shuffle + local sortlocal-sort: sort rows only within each compaction task without global shuffle,producing files that are internally ordered by clustering columns
The local-sort mode is cheaper (no network shuffle) and sufficient for
per-file Parquet lookup optimizations (PIP-42), where only intra-file
ordering is required.
