Redis::KeyHash

Tests of key hash slot agreement for use with Redis Cluster and RedisLabs Enterprise Cluster.

Installation

Add this line to your application's Gemfile:

gem 'redis-key_hash'

And then execute:

$ bundle

Or install it yourself as:

$ gem install redis-key_hash

Usage

require 'redis/key_hash'

# As syntactic sugar, expose Redis::KeyHash methods in the Redis class.
#
Redis.include Redis::KeyHash

# Test whether several keys will hash to the same slot.
#
if Redis.all_in_one_slot?('a','b')
  'happy'
else
  'sad'
end
Redis.all_in_one_slot!('a','b') # may raise Redis::ImpendingCrossSlotError

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test 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.
