*master* and several *slaves" *seems to imply that the election is
per-queue, just trying to confirm.
Mirrored queues are great, however there is still the thorny issue of being
limited to the throughput of the master when you've got one queue that has
lots of messages in it.
If the election process operates on a per queue basis, then it would be
possible to declare multiple queues to the same exchange and effectively get
load balanced usage of the cluster with all the goodness of high
availability.

Hello together<br>
<br>
I heard about the rabbitmq-ha-test developed by rabitmq as an experimental =
feature and I have download the source code from github.<br>
I am considering a high availability broker setup using the rabbitmq-ha-tes=
t code and I wanted to check if there is someone here who could help with e=
xperience/advice.<br>
<br>
<br>
<br>
I have searched on google for a long while and I got nothing about the func=
tion and setup of these code.<br>
<br>
Is these code used for clustering or active/passive HA?<br>
<br>
Using the rabbitmq-ha-test, there is no message to be lost when a rabbitmq-=
node is down, is this right?<br>
<br>
<br>
<br>
Meanwhile, what is the right way to setup these source code?<br>
I am not quite familiar whit erlang, so I just download the code and don=
9;t know what to do next.<br>
<br>
Any ideas or hints will be much appreciated.<br>
