Queue

As explained in Quarkus in Action

A queue is an ordered messaging destination that stores messages until consumers receive them.

How Quarkus in Action covers it

How deep it goes

Defines queue-based delivery and demonstrates extension, channel, naming, and consumer configuration without detailing broker internals.

Examples

Uses reservation invoices, the invoices exchange, the invoices queue, and BillingService consumption.

What it assumes

Builds on Quarkus reactive messaging channels and assumes a Reservation service that already produces invoices.

What you can do after

Apply it via Quarkus and SmallRye Reactive Messaging to produce and consume RabbitMQ messages.

How it connects

Connects queues with RabbitMQ, exchanges, message brokers, AMQP, and reactive messaging.
