Improving LZ4 for Effective Compression and Efficient Query
Summary: Extends LZ4 with LZV, using variable-length hashes to find longer matches, improving compression ratio while reducing match-dependency costs. Adds auxiliary-index and prediction-guided key search to query compressed data directly in TsFile, avoiding full decompression and cutting latency. (summarized by gpt-5-mini on Apr 11 2026)
