Have your cake and decompress it too
Summary
A technical piece detailing Vortex's BtrBlocks-inspired, recursive cascading approach to per-column compression that outperforms Parquet+ZSTD on size and decompression speed for TPC-H workloads. It compares Parquet's two-layer encoding with Vortex's adaptive cascade, explains sampling for codec selection, discusses per-column configurability, and notes how Vortex diverges from the original BtrBlocks paper, with a look ahead to future developments.
