From paying attention to open source, to using open source, and then participating in open source contribution, more and more domestic developers build their businesses through open source technology.

So far, Arthas/Dubbo/ChaosBalde/Nacos/RocketMQ/Seata/Sentinel/Spring Cloud Alibaba/Tengine and other open source projects in the field of microservices are available on GitHub I have obtained nearly 8W stars and the number of contributors has reached 738. In a way of community cooperation, I have improved the production efficiency and distribution efficiency of the project.

In this process, everyone is both the developer and the user of the project. As the demander of the project, they participate in the iterative process of the project, so that the project can meet the actual demand with faster response speed and quickly iterate “good” products, which seems to be difficult to achieve in other ways of collaboration.

Often, we keep up with the community by subscribing to a mailing list on GitHub. This time, we cooperate with the leaders of the above open source projects to release the “Micro service Open Source Ecological Report”, which collects the recent community dynamics of each open source project and helps developers to know the latest progress of each open source project more efficiently.

Community dynamics include, but are not limited to:

  • release
  • Personnel dynamic
  • Project dynamics and planning
  • Training and activities

We welcome other open source projects in the field of micro services in China to send us recent community trends, and we will release them together. Click here and leave us a message on the background of our official account. We will contact you as soon as possible.

The following is the content of the first issue of “Microservices Open Source Ecology Report”.

A, Apache Dubbo

1. Personnel Dynamics:

Three new committers are added to the community:

  • Dubbo-erlang maintainer, from Xeseng School of Ping An One Wallet, Erlang is also the 6th language supported by Dubbo, GitHub ID @dlive;
  • Yueneng Xie from Alibaba, contributed a lot to Dubbo 3.0, providing RSocket support, GitHub ID@uglycow;
  • Leishunyu from daso has made a lot of improvements and optimizations in the Dubbo core including the official website, and reviewed a lot of pull requests, GitHub ID @leishunyu;

2. Project dynamics and planning

  • In this year’s Google Summer of Code, the topic is intelligent load balancing based on server response. The Code submitted by Daniela Morais from Brazil has entered the development stage. We discussed the implementation scheme together and initially planned to adopt the way of server callback. To complete the transfer of server data;
  • Dubo-website supports automatic construction, only need to submit markdown format, the system will automatically build static code and upload;
  • The completableFuture.get () method in Java 8 uses spin to wait, which causes some CPU overhead. The community is discussing a fix: details
  • The community is discussing to publish an authoritative guide to Dubbo based on the current documents. At present, many students are willing to participate in the construction. The Alibaba/Metrics component is providing support for Prometheus, details;

Second, the Apache RocketMQ

1. Project dynamics and planning

RocketMQ has completed the binding with CNCF CloudEvents standard, which is the first proprietary protocol bridge design of open source software in China. In the future, Events support capability will be continuously completed in the Serverless field.

2. Training and activities:

RocketMQ Meetup city station is a community initiative, similar to Google GDG’s developer salon. At present, the preparatory work of Suzhou, Beijing, Shanghai and Chengdu stations has been completed, and the working group of city station alliance has been established.

  • 13:00-17:00, June 29, Beijing Urban Community Developer Salon, details;
  • On June 29, 18:00, Beijing Urban Community Developer Training Camp will be held, details;
  • Apache RocketMQ × Apache Flink Meetup Shanghai 13:00 — 18:00 July 6th, Details;

Third, Arthas

1. Project dynamics and planning

The community has launched a Arthas online tutorial survey, asking for suggestions for improvements. The online tutorials are both basic and advanced, designed to help developers quickly get started with Arthas and diagnose difficult problems.
