LeCo: Lightweight Compression via Learning Serial Correlations
Summary: LeCo uses learned models to remove serial redundancy in columnar data, unifying FOR, Delta, and RLE as a single framework. Real and synthetic data show Pareto gains in compression and random access; Arrow yields up to 5.2x speedups, RocksDB 16% throughput gain.
