In rabbitmq, queue is a buffer that stores a messages that are sent from the exchanges to queues. In our experience, lazy queues create a more stable cluster with better predictive performance. The quorum queue type is an alternative to durable mirrored queues purpose built for a set of use cases where data safety is a top priority.

Rabbitmqs default behavior is to cache messages in memory and to move them to disk only when the broker needs more available memory. Sometime the gc never ends 😬 but thats another topic) i can not loose message, so my queue is durable, and i publish with delivery_mode=2.
