Bloom filter

Golang bloom filter library with support for both bitset and redis backends.

Tests and benchmarks

It's easy to run the tests and benchmarks.

make test

This will try to connect to Redis listening on the default port (6379) running on localhost.

You can supply the environment variable REDIS_HOST in case you are not running redis on localhost.

REDIS_HOST=192.168.33.10 make test

Benchmarking

Benchmarking results on my Macbook Pro Mid 2014 (2.5 ghz Intel Core i7, 16 GB RAM, with "flash" drive (SSD?)), running redis locally with no special configuration.
