RedisCluster

RedisCluster for ruby is rewrited from https://github.com/antirez/redis-rb-cluster

Now is developing, only support single node methods, and not use in any production environments.

Installation

Add this line to your application's Gemfile:

gem 'redis_cluster'

And then execute:

Or install it yourself as:

$ gem install redis_cluster

Usage

Doing!

hosts = [{host: '127.0.0.1', port: 7000}, {host: '127.0.0.1', port: 7001}]  # don't need all, gem can auto detect all nodes, and process failover if some master nodes down
rs = RedisCluster.new hosts
rs.set "test", 1
rs.get "test"

Benchmark test

A simple benchmark at my macbook, start 4 master nodes (and 4 cold slave nodes), running with one ruby process. This only testing redis_cluster can work, not for redis Performance. When I fork 8 ruby process same time and run get command，redis can run 80,000 - 110,000 times per second at my macbook.

Benchmark.bm do |x|
  x.report do
    1.upto(100_000).each do |i|
      redis.get "test#{i}"
    end
  end
  x.report do
    1.upto(100_000).each do |i|
      redis.set "test#{i}", i
    end
  end
  x.report do
    1.upto(100_000).each do |i|
      redis.del "test#{i}"
    end
  end
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
