## What - Cache repeated Arrow dictionary paths while grouping positional deletes. ## Why - Each row currently resolves its dictionary value and looks up the path. ## Implementation - Reuse the builder or rejected-target result for each dictionary index in a chunk. - Keep plain strings and large dictionaries on the uncached path. ## Benchmark - Isolated grouping benchmark: 262,144 rows, Go 1.26.3, Apple M1 Pro, median of 5 paired runs. - 16 paths: 9.05 ms to 3.84 ms (2.4x faster). - 512 paths: 10.57 ms to 4.95 ms (2.1x faster). -- This is an automated message from the Apache Git Service.
