ApsaraMQ for RocketMQ:Release notes

更新時間:Sep 24, 2024

This topic describes the release notes for the TCP client SDK for C++. The release notes include the release date, download link, and feature updates for each release. You can select a version of the TCP client SDK for C++ that meets your business requirements to send and receive messages based on the description of this topic.

After you obtain the TCP client SDK for C++, you must prepare an environment based on the usage notes of the SDK for C++. The procedure for preparing an environment varies based on the version of the SDK.

  • For information about how to prepare an environment for the SDK V1.x.x , see Environment preparation (V1.x.x).

  • You can use the TCP client SDK for C++ V3.x.x to access only instances that contain namespaces. If the instance that you use does not contain a namespace, do not upgrade the TCP client SDK for C++ to V3.x.x.

    By default, all ApsaraMQ for RocketMQ 5.x instances contain namespaces. If you use an ApsaraMQ for RocketMQ 4.x instance, you can check whether the instance contains a namespace in the Basic Information section of the Instance Details page in the ApsaraMQ for RocketMQ console.

Optimized feature

  • Load balancing: Load balancing is performed based on messages. This makes message loads more balanced.

  • Dashboard: Various metrics are added. The added metrics include the number of accumulated messages and the duration and success rate of each step from message production to message consumption.

  • Message trace: More parameters are included in trace query results. These parameters are related to scheduled messages, delayed messages, transactional messages, and message consumption.

  • Ordered messages: The maximum number of retries is changed to 16.

  • Broadcasting consumption: The consumer offset can be customized when you start a consumer.

  • Push mode: The consumption throttling feature is supported. The processing logic is optimized for scenarios in which the number of consumption threads is abnormal.

  • Changes in API operations.
