About:
xxHash is an extremely fast non-cryptographic hash algorithm designed for high-performance data integrity checks and hash-based data structures. It offers processing speeds measured in multiple gigabytes per second per core, making it ideal for large-scale data processing. The algorithm provides excellent distribution properties while maintaining a low CPU footprint.
Key Features:
  • Speed: Multiple GB/s per core
  • Low CPU footprint
  • 64-bit and 128-bit variants
  • Excellent hash distribution
  • Streaming API support
Use Cases:
  • Hash tables and bloom filters
  • Data deduplication
  • File integrity verification
  • Large dataset processing
Alternatives:
  • CityHash – Google's hash, similar speed but xxHash is generally faster
  • MurmurHash – Widely used but slower than xxHash
  • CRC32 – Cryptographic but much slower, not suitable for non-crypto needs
