[rabbitmq-discuss] Durable queues and exchanges

Tue Jan 13 22:53:04 GMT 2009

Hello,

Quick question. I realize that for a message to survive a reboot, the
queue and exchange have to be marked durable, and the message itself
needs to use delivery_mode=2. That being said, does marking a queue
and exchange durable only flag them to be recreated automatically on a
reboot, or does it start some kind of logging? Put another way, does
setting a queue/exchange to durable have a performance hit on its own?
Thank you in advance.
