Proposals need to include appropriate details and scope of impact. Please elaborate as much as possible on the requirements.We hope to get more complete information for the following reasons:

  • The improvements and new features implemented ultimately fit your needs
  • Evaluate input costs and design solutions based on your needs

If you plan to implement your proposal to contribute to the community, you will also need to provide detailed description information,And follow code-guidelines Code specification

We recommend building community consensus before implementing features. By discussing the need for new features and how to implement them, proposals that are outside the scope of the project can be spotted early.

Test pre-release versions​

Apache RocketMQ continues to grow with the help of its active community. Every few weeks we release a new version of RocketMQ to fix bugs, improve performance, add features, etc. The process for releasing a new version is as follows:

  1. Launch a new pre-release version and start the voting process (72 hours)
  2. Test pre-release versions and score (+1 no problem found, -1 test problem)
  3. If the pre-release version is not tested, release it; otherwise, go back to Step 1

We have compiled the release-manual release guide on the website. Testing a pre-release is a big job, and we need to get more people involved. The RocketMQ community encourages everyone to participate in testing the new version. By testing the pre-release version, you will be confident that the new RocketMQ version will still service your program properly and is indeed supporting version upgrades.

Contribute code​

Apache RocketMQ has been and will continue to be maintained, optimized, and extended. So Apache RocketMQ encourages everyone to contribute source code.To give code contributors and reviewers a great code contribution experience and provide a high quality code repository, the community follows the contribution process in code-guidelines.The coding manual contains guidelines for building a development environment, community coding guidelines and coding styles, and describes how to submit contributed code.

How do I become a committer​

Committers are members of a community's project repository who can modify code, documents, and websites or accept contributions from other members.

There is no strict protocol for becoming a commiter, and candidates are usually active contributors in the community.

Being an active contributor means: participating in discussions on email lists, helping others solve problems, verifying pre-release versions, honoring the good people and continuously optimizing community management, which is part of the community in Apache.

Undoubtedly, contributing code and documentation to the project is equally important. A good place to start is by optimizing performance, developing new features, and fixing bugs. Either way, you are responsible for contributing code, providing test cases and documentation, and maintaining it continuously.

Candidates can be recommended by committer or PMC members in the community, and ultimately voted on by the PMC.
