BtrBlocks: Efficient Columnar Compression for Data Lakes
Summary: BtrBlocks is an open columnar format optimized for data lakes on object stores, addressing remote-scan inefficiencies in Parquet-based pipelines. Lightweight encodings yield fast decompression and strong compression, lowering CPU-bound query latency for cloud analytics. (summarized by gpt-5-nano on Feb 09 2026)
