The goal of pybloomfiltermmap is simple: to provide a fast, simple, scalable,
correct library for Bloom Filters in Python.
See http://axiak.github.com/pybloomfiltermmap/.
After you install, the interface to use is a cross between a file interface and a ste interface. As an example:
>>> 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
You may or may not want to use Cython. If you have it installed, the setup file will build the C file from the pyx file. Otherwise, it will skip that step automatically and build from the packaged C file.
To install:
$ sudo python setup.py install
and you should be set.
Mac users may face problems when installing the package, it happens because on the build, the compiler tries to import a module that is provided by OpenSSL, and most of the cases it fails because it can't find the module. What to do in these cases:
- Make sure openssl is installed
brew install openssl - Set an environment variable that tells the path to the openssl installed
export CFLAGS="-L/usr/local/opt/openssl/lib -I/usr/local/opt/openssl/include" - You may need extra flags to the compiler, check with
brew info openssl
