Scaling RabbitMQ with shared exchanges

Sharded exchanges can be enabled by using the a plugin with rabbitmq. It is useful for distributing load across multiple queue for the same routing keys.

Using sharded exchanges, you can shard messages across the cluster so that a single node doesn’t become overwhelmed.
