[rabbitmq-discuss] HA-aware clients?

Mon Sep 24 09:57:39 BST 2012

Hi Alex,

You'll need to handle reconnecting explicitly in the client(s) yourself. 
What HA does is ensure that any time you connect to a node on which a 
queue is mirrored, you get a consistent view of the queue and obviously 
it deals with failover when a node dies.
