Hi. I am just reading up about the concept of HAProxy load-balanced warrens
(active / standby nodes) and I can't quite come up with a solution to a
I understand that the concept of the load balanced warren is for HAProxy to
automatically fail over to the standby node, should the active node fail
and go down. In doing so, any existing messages on the active node would be
lost until this node is brought back up.
Which brings me to my question, what happens to the pending (still to be
consumed) messages on the standby node when the active node is brought back
up. Are they lost, or should the application logic handle this itself?
Because as far as I know, HAProxy has no way of dealing with this issue.
