permette di pubblicare da PHP eventi con parametri in una coda, un processo(anche inuna seconda macchina) leggerà la coda e processerà il da farsi

if you had a website front end written in PHP that was responsible for uploading and then processing a large amount of user photos or videos? You may want to shift the processing burden to speedier or specialized language that can run in the background or on a different server instance. RabbitMQ can be configured as a worker queue for such a situation.
