Bloom Filter 2

bloom-filter2 is a pure Python Bloom filter module, providing a space-efficient and probabilistic set data structure. It supports mmap, in-memory, and disk-seek backends, offering a balance between memory usage and performance. The library automatically calculates optimal Bloom filter parameters based on user-specified maximum elements and desired false positive rate. It is compatible with CPython 3.x, Pypy, and Jython and is actively maintained.
