Overview
This ruote storage can be used in two modes : client and server.
Beanstalk is the medium.
client
The storage is pointed at a beanstalk queue
engine = Ruote::Engine.new(
Ruote::Worker.new(
Ruote::Beanstalk::BsStorage.new('127.0.0.1:11300', opts)))
All the operations (put, get, get_many, …) of the storage are done by a server, connected to the same beanstalk queue.
server
The storage point to a beanstalk queue and receives orders from clients via the queue.
Ruote::Beanstalk::BsStorage.new(':11300', 'ruote_work', :fork => true)
Note the directory passed as a string. When in server mode, this storage uses an embedded Ruote::FsStorage for the actual storage.
The :fork => true lets the storage start and adjacent OS process containing the Beanstalk server. The storage takes care of stopping the beanstalk server when the Ruby process exits.
