> A RabbitMQ stream models an append-only log with non-destructive consuming semantics

> Streams in RabbitMQ are persisted and replicated. This translates to data safety and availability (in case of the loss of a node)

Let's talk about the elephant in the room: Do streams replicate the same way queues do? If you ever lost a node while you had a few GBs of data in queues you will know that bringing a node back will sync all data over the net while completely blocking ANY operation on the queue until this process finishes. Please don't recommend quorum queues, they lack important features as well.
