What Is TDMQ for RabbitMQ
Last updated: 2026-01-05 09:36:07
TDMQ for RabbitMQ is a message queue service independently developed by Tencent. It supports the AMQP 0-9-1 protocol and is fully compatible with the components and concepts of open-source RabbitMQ. It also has underlying strengths of compute-storage separation and flexible scaling.
TDMQ for RabbitMQ provides highly flexible routing to accommodate various business message delivery rules and can buffer upstream traffic pressure to ensure stable operation of the message system. It is commonly used for asynchronous communication and service decoupling between systems, reducing dependencies among different services. It is also widely applied in distributed systems within industries such as finance and government.
Basic Architecture
The basic architecture diagram of TDMQ for RabbitMQ is as follows:
Basic concepts:
Producer (P): sends messages to the exchange.
Connection: a TCP connection, which is a physical TCP connection between producers or consumers and TDMQ for RabbitMQ.
Channel: Multiple channels can be established within each physical TCP connection on the client side, with each channel representing a session task.
Vhost: provides logical isolation. Exchanges and queues in different vhosts are isolated at the data level and do not interfere with each other.
Exchange (X): a component that receives messages from producers and routes them to queues.
Queue: a buffer that stores messages for consumption by consumers.
Consumer (C): pulls messages from the queue for consumption.
Message sending and receiving process:
After users establish a connection between the client and the RabbitMQ server, efficient message interaction is achieved based on channels. Producers send messages to exchanges through channels, and the exchanges route messages to target queues according to binding rules. Consumers pull messages from queues through channels to complete business logic processing.
Quick Navigation
TDMQ for RabbitMQ provides two product forms: Managed Edition and Serverless Edition. Serverless Edition adopts an innovative storage-compute separation architecture and is compatible with the AMQP 0-9-1 protocol and all components and concepts of open-source RabbitMQ. Through architecture upgrades, it effectively resolves common stability issues of the open-source version, such as split-brain and vulnerability to message backlogs, while providing strengths such as stability, security, and flexible scaling.
