Adds support for Elasticache failover to the Ruby driver of the redis-rb gem. Elasticache replication groups can transparently promote a new node to master, but TCP connections are persistent. This patch makes READONLY error messages from Redis get handled like a connection error instead of a command error so redis-rb will self heal the connection and run the command against the new master node.
Add this line to your application's Gemfile:
In your gemfile
gem 'redis-elasticache'And then execute:
$ bundle
Or install it yourself as:
$ gem install redis-elasticache
In an environment that is backed by an Elasticache Replication Group.
