RedisBitmaps

This gem should make it easy to create and use large bitmaps to do stat-tracking and metrics as seen in this post (http://blog.getspool.com/2011/11/29/fast-easy-realtime-metrics-using-redis-bitmaps/).

Installation

Add this line to your application's Gemfile:

gem 'redis_bitmaps'

And then execute:

$ bundle

Or install it yourself as:

$ gem install redis_bitmaps

Usage

Configure the default Redis connection:

RedisBitmaps.configure do |config| config.host = 'localhost' config.port = 6379 end

Create a bitmap:

active_users = RedisBitmaps.new('active_users')

When a user logs in:

active_users.set(user.id, 1)

When a user logs out:

active_users.set(user.id, 0)

Count active users:

active_users.count(1)

Count inactive users:

active_users.count(0)

Count total users:

active_users.total
