Quite. Although I do see that there are efforts underway to overcome this.

I am curious to hear about how everyone is deploying MySQL and RabbitMQ in
active/active environments. My experience so far with MySQL in a
multi-master configuration, but an active/passive usage, is less than
steller. I have to watch the sync like a hawk and implement a ton of
monitoring around that to be sure that it's not only actively working, but
that the tables on master and slave are actually like-for-like.

Without hijacking the thread - any tips? Is Galera clustering really that
much better?
