[rabbitmq-discuss] Apache/PHP_mod and keeping connection alive

Sat Apr 5 16:51:41 BST 2014

Hi,

Note that you don't need to declare the queue/exchange every time. You
can have that setup in advance and use your connection to just send
the message.

About RabbitMQ being overloaded by this, unless you are on the several
thousands, I doubt it would be a problem. As always, it's better to
benchmark this yourself.

Regards,

Alvaro
