### Problem Summary: Sparse row ID reads on nullable columns traversed every null-map run between selected rows, causing unnecessary decoding work for large gaps. ### Solution: Add an optimized RleDecoder<bool>::Skip implementation that processes literal values in 64-bit chunks and counts skipped nulls. Use it to advance null-map and data-decoder positions efficiently while preserving correct behavior for both normal and null-map-only reads. -- This is an automated message from the Apache Git Service.
