On a bit unrelated note, if you want to handle very large Bloom filters (billions of entries with low false positive rates) there is an open source Java library that can help you to do that: https://github.com/nixer-io/nixer-spring-plugin/tree/master/....

There is also a command line utility that accompanies the library: https://github.com/nixer-io/nixer-spring-plugin/tree/master/....
