A Celluloid::IO-based connection backend for the redis-rb gem, providing "evented" connection support that can multiplex long-lived blocking calls like pub/sub and blpop(rpush) with the Celluloid message protocol.


Unlike EventMachine, Celluloid::IO ideally does not need to provide separate "Celluloid-enabled" versions of each and every library that ever does any kind of I/O, but can instead leverage dependency injection APIs that tell libraries to use Celluloid::IO::TCPSocket instead of TCPSocket.

Unfortunately, the redis-rb gem is a bit gnarly and does a lot of strange things like monkeypatching its own subclasses of TCPSocket and UNIXSocket in attempts to add better timeout handling.

Rather than trying to inject itself into that mess, this gem provides Redis::Connection::Celluloid which seeks to be a drop-in replacement for Redis::Connection::Ruby.


Add this line to your application's Gemfile:

gem 'celluloid-redis'

And then execute:

$ bundle

Or install it yourself as:

$ gem install celluloid-redis

Require it in your Ruby application with:

require 'celluloid/redis'


When instantiating the client object, specify :celluloid:

redis = Redis.new(:driver => :celluloid)
