What it does

Works today

  • CRC-32 for page CRCs and deletion-vector checksums
  • MurmurHash3 for the Iceberg bucket[N] transform
  • XXH64 for Parquet bloom filters
  • Identical results on every platform

Correctness

Checked against zlib, mmh3 and xxhash, plus the Iceberg spec's Appendix B vectors
