Facebook open sources C++ F14 hash table ZDNET
F14 is a 14-way probing hash table that resolves collisions by double hashing. Up to 14 keys are stored in a chunk at a single hash table position. Vector instructions (SSE2 on x86_64, NEON on aarch64) are used to filter within a chunk; intra-chunk search takes only a handful of instructions. See more The core hash table implementation has a pluggable storage strategy,with three policies provided: F14NodeMap stores values indirectly, calling malloc on each insert … See more F14 introduces randomness into its behavior in debug builds and whenthe address sanitizer (ASAN) is in use.
