AMQP 0-9-1

AMQP 0-9-1 is a message-oriented protocol built around exchanges, queues, bindings, and acknowledgments. It is commonly used for work queues, asynchronous service integration, and routing messages to competing consumers.

Enterprise Edition

AMQP 0-9-1 support is available exclusively in the FlowMQ Enterprise Edition.

Supported Features

• Standard AMQP 0-9-1 clients
• Direct, topic, fanout, headers, and default exchanges
• Queues and bindings
• Durable queues and persistent messages
• Manual acknowledgments
• Competing consumers
• Message properties and headers

Common Use Cases

• Background job processing
• Worker queues
• Asynchronous microservice communication
• Enterprise application integration
• Routing messages to multiple queues
• Reliable command and task delivery

Limitations and Compatibility Notes

• AMQP transactions (tx.select, tx.commit, and tx.rollback) are not supported.
• For durable queues, the delivery-mode message property is ignored. All messages enqueued in a durable queue are treated as persistent, including messages published with delivery mode 1 (non-persistent).
• For performance, the prefetch-count specified by basic.qos is applied separately to each consumer, rather than as a channel-wide limit.
