Good to know -- I suspected as much, but I wasn't certain. The queues
and exchanges in question are definitely non-durable, though.
Other parts of the system do use durable queues and exchanges: would the
creation or binding of durable queues via a separate connection to
Rabbit have the potential to impact a connection not dealing in durable
Also, does the fsync occur only on the initial creation of the durable
queue, exchange, or binding? Or does Rabbit hit the disk every time a
client asserts that a durable object exists?
