Fast Python Bloom Filter using Mmap

pybloomfiltermmap3

pybloomfiltermmap3 is a Python 3 compatible fork of pybloomfiltermmap by @axiak.

The goal of pybloomfiltermmap3 is simple: to provide a fast, simple, scalable, correct library for Bloom Filters in Python.

Quickstart

After you install, the interface to use is a cross between a file interface and a ste interface. As an example:

    >>> import pybloomfilter
    >>> fruit = pybloomfilter.BloomFilter(100000, 0.1, '/tmp/words.bloom')
    >>> fruit.update(('apple', 'pear', 'orange', 'apple'))
    >>> len(fruit)
    3
    >>> 'mike' in fruit
    False
    >>> 'apple' in fruit
    True

To create an in-memory filter, ditch the file location.

    >>> cakes = pybloomfilter.BloomFilter(10000, 0.1)

Caveates: It is currently not possible to persist this filter later.
