💥 Cython hash tables that assume keys are pre-hashed

Project mention: Is anyone using PyPy for real work? | news.ycombinator.com | 2023-07-31

If you have very large dicts, you might find this hash table I wrote for spaCy helpful: https://github.com/explosion/preshed . You need to key the data with 64-bit keys. We use this wrapper around murmurhash for it: https://github.com/explosion/murmurhash
There's no docs so obviously this might not be for you. But the software does work, and is efficient. It's been executed many many millions of times now.
