Good to the Last Bit: Data-Driven Encoding with CodecDB
Summary: CodecDB is an encoding-aware columnar DB that tightly couples data-driven encoding selection with encoding-aware query operators to exploit encoded data. It attains ~90% encoding accuracy, up to 40% better compression, and ~10x TPC-H speedups and ~3x SSB speedups. (summarized by gpt-5-nano on Feb 09 2026)
