  • uses python and rabbitMQ
  • relies on a singe rabbitMQ server (could have multiple shoal servers easily but they rely on rabbitMQ. Getting multiple rabbit servers co-operating would be difficult but may not be necessary for load TODO: link Mike Chester's WT report
  • relies on a singe rabbitMQ server as of now but could be expanded to use a [[http://www.rabbitmq.com/clustering.html][cluster]. Note clusters do not work well over WAN and should be on the same network (though it seems there is third party plugins to enable arbitrary clusters).
  • shoal-agent and shoal-server require IP of rabbitMQ server, shoal-client requires IP of shoal-server
  • shoal-client writes the CVMFS config file when run
  • shoal-server will remove an agent from its list after a configurable period of inactivity
