Quorum Queue, so they don't need a policy for replication/mirroring any more?

[Andrew P]

Hi

Sorry for what may be a silly question but not found the answer for this question yet, the question is:

Previously before quorum queues you had to declare a policy with a ha-mode in order to mirror the data onto other nodes in the cluster. Am I correct in thinking that quorum queues define the x-quorum-initial-group-size argument, so mirroring/replication is done directly from the queue declaration, and we no longer need to define a policy for this? 

e.g.:

rabbitmqadmin -u andrew -p test declare queue --vhost=/ name=MyQuorumQueue queue_type=quorum durable=true arguments='{"x-quorum-initial-group-size": 2}'

Many thanks

Andrew

Hi,

Yes, you don't need any policy. The default of x-quorum-initial-group-size is 3, so in most cases you don't have to specify anything at all.

However, this value should be an odd number. Do not set it to 2.

Best,
