This document describes how to quickly use TDMQ for RocketMQ to send and receive normal messages and the related considerations.
Usage Instructions
TDMQ for RocketMQ supports four message types: normal messages, scheduled/delayed messages, ordered messages, and transactional messages. This document takes normal messages as an example to introduce message sending and receiving. For other message types, see Message Types.
Note:
Different message types cannot be mixed. Therefore, a topic you created for normal messages cannot be used to send and receive other types of messages.
TDMQ for RocketMQ supports access based on HTTP and TCP protocols. Therefore, it is recommended to create a group for each protocol. This document takes the TCP protocol as an example.
Note:
If multiple consumers use the same group to consume messages, with certain consumers using the TCP protocol and others using the HTTP protocol, it may lead to consumption failures, message duplication, or message loss.
TCP and HTTP protocols both support public network and VPC network access addresses. The VPC network is recommended by default for production environments. Public network access is disabled by default. For more information about how to enable or disable public network access, see Configuring Public Network Access. Public network access is recommended only for scenarios such as testing and debugging that do not affect the production environment.
Note:
The TCP protocol and HTTP protocol are supported in all regions. If you are unable to use the HTTP protocol in the current instance region, you can submit a ticket for application.
Operation Process
The operation process for getting started varies depending on the cluster type. The following diagram illustrates the process for sending and receiving messages using TDMQ for RocketMQ.
