Transactional Order Processing with RocketMQ

Scenario

Build a distributed order processing system that sends transactional messages with custom metadata (order tags, keys) for guaranteed delivery, then consumes and acknowledges messages filtered by those attributes.

How the products combine

See rocketmq/rocketmq-send-guarantees.

2. rocketmq · rocketmq-configure-attributes — RocketMQ — Configure message metadata and custom attributes

See rocketmq/rocketmq-configure-attributes.

3. rocketmq · rocketmq-consume-logic — RocketMQ — Consume and process incoming messages

See rocketmq/rocketmq-consume-logic.

4. eb · eb-deliver-destinations — EventBridge — Deliver events to external destinations (API/OSS/MQTT)

See eb/eb-deliver-destinations.

Q: How do I build an order processing system with RocketMQ? A: You build a distributed order processing system by sending transactional messages with custom metadata like order tags and keys to ensure guaranteed delivery. This architecture combines RocketMQ skills for sending guarantees, configuring attributes, and consuming logic with EventBridge to deliver events to external destinations.

Q: What is the workflow for sending and consuming transactional messages in RocketMQ? A: The messaging workflow consists of sending transactional messages with delivery guarantees, then consuming and acknowledging messages filtered by those custom attributes. Implementation relies on dedicated RocketMQ components for guaranteeing delivery, configuring message metadata, processing incoming messages, and routing events via EventBridge.
