Redis::SlaveRead

Provides for distribution of slave reads in a Redis cluster.

Installation

Add this line to your application's Gemfile:

gem 'redis-slave-read'

And then execute:

$ bundle

Or install it yourself as:

$ gem install redis-slave-read

Usage

Rather than using a Redis instance, create a wrapper that wraps multiple Redis connections.

master = Redis.new "localhost:6379"
slave1 = Redis.new "localhost:6389"
slave2 = Redis.new "localhost:6399"
$redis = Redis::SlaveRead::Interface::Hiredis.new(master: master, slaves: [slave1, slave2])

Make sure that your slaves are set to be slaved to the master, like slaveof localhost 6379

Now, you can treat your SlaveRead interface as a normal Redis interfaces. Reads are distributed among the slaves, and writes are always sent to the master. Writes will be propagated to slaves by the master:

$redis.set "foo", "bar"
$redis.get "foo"
