### Problem Summary: Array sparse reads performed a seek and single-row read for every selected row, causing repeated offset and item-page access that scaled poorly with large row ID batches. ### Solution: Bulk-read each selected row’s start and end item offsets, use the page-tail sentinel for the segment’s final row, and merge adjacent item spans into sequential reads. Preserve nullable payloads and existing OFFSET_ONLY, NULL_MAP_ONLY, and lazy materialization semantics. -- This is an automated message from the Apache Git Service.
