.redis_connect ⇒ Object
(Re)Connect all the redis connections

# File 'lib/redised.rb', line 28 def self.redis_connect @_redis_connections.collect do |params, redis| redis.client.connect [params, redis.client.connected?] end end |
.redis_connection(params) ⇒ Object
Get a reusable connection based on a set of params. The params are the same as the options you pass to ‘Redis.new`
This ensures that an app doesnt try to open multiple connections to the same redis server.
