[rabbitmq-discuss] rabbitmq cluster failover for persistent queues

Sun Jul 26 01:30:00 BST 2009

Hello,

Although this is my first post to the rabbitmq-discuss list, I've enjoyed
reading the archives over the last few days.  We're evaluating rabbitmq for
a system at work.  One apparent limitation that we've run into is that while
exchange information (which node a queue lives on, etc.) is replicated each
node itself seems to be a single point of failure in that if it goes down
then a message whose routing key only matches bindings to queues on that
node will be dropped.  That is, from what I understand it appears that
although the contents of persistent queues are /recoverable/ in the event of
a disaster I don't see a built-in way of having another node in the cluster
"take over" a queue which previously lived on a node which has just gone
down.

I'd like to know whether a) I've missed something in my interpretation of
how rabbitmq server handles persistent queues in a cluster and b) if this is
indeed the current behavior what other rabbitmq users have done to provide
fault tolerance.

I appreciate any insight into how people solve these issues with rabbitmq.
Thanks in advance.
