Have your cake and decompress it too

https://spiraldb.com/_next/image?url=%2Fimages%2Fposts%2Fcascading-compression-with-btrblocks.jpg&w=3840&q=90
We've written about individual compression codecs in Vortex before: FastLanes for bit-packing integers, FSST for strings, and ALP for floating point. But we've never explained how Vortex decides which codec to use for a given column, or how it layers multiple codecs on top of each other. On TPC-H at scale factor 10, Vortex files are 38% smaller and decompress 10–25x faster than ...
