“Open Source”, a familiar word in the programmer world, is almost full of our entire career. In recent years, the Chinese have also contributed a lot of excellent open source projects and products, and even some have received recognition and praise from foreign counterparts. Let’s take a look at the great open source projects that come from China and go to the world!



KylinTM is the first Chinese work to become Apache’s top open source project. It is a distributed analysis engine that provides SQL query interface and multi-dimensional analysis (OLAP) capabilities on top of Hadoop to support very large-scale data and can handle terabytes and even petabytes of analysis tasks. It can query huge Hive tables in sub-seconds and support high concurrency.

Kylin’s core idea is precomputation (space-for-time), which pre-calculates the metrics that may be used in multi-dimensional analysis, and saves the calculated results as cubes for direct access during queries. Converting high-complexity aggregation operations, multi-table joins, and so on into queries for precomputed results determines that Kylin has good fast queries and high concurrency.

On November 28, 2016, Alibaba announced the donation of open source distributed messaging middleware RocketMQ to Apache as an Apache incubator project. During the incubation period, RocketMQ completes product specification in terms of coding protocol, branch model, continuous delivery, release protocol, etc., and continuously listens to and feedbacks the community, covering e-commerce, Internet of Things, finance, big data and many other fields, and has connections. Other top open source ecosystems (such as Spark, Ignite, and Storm).

RocketMQ is from China but has attracted worldwide attention. RocketMQ not only won the CJK OSS Award in the 2015 China-Japan-Korea Open Source Forum, but also has entered the mainstream open source portal of Europe and the United States. Currently, more than 100 companies and research institutions are using RocketMQ. It is worth mentioning that the United States is currently the second RocketMQ in the world. Large visiting country.

On September 25, 2017, the Apache Software Foundation officially announced that Alibaba.com’s open source project RocketMQ, which was donated to the Apache community, officially graduated from the Apache community and became the Apache Top Project (TLP). Since then, Apache RocketMQ has become the first Apache top-level project in China that is not the first Hadoop ecosystem and the first Internet middleware in China. This means that Chinese technology has entered the international arena and has taken the lead in international open source projects.

Pulsar is a distributed messaging/subscription delivery platform designed to achieve scalability and flexibility while ensuring no data loss. The project was open sourced by Yahoo in 2015 and submitted to the Apache incubator in June 2017.

Pulsar’s original goal was to create a multi-tenant scalable messaging system, and as such, its unique architecture that separates the service area from the storage tier has proven to be a key advantage. These two layers of architecture enable Pulsar to provide a very simplified approach to cluster operations, allowing operators to easily scale clusters and replace failed nodes, or provide higher write and read availability.

Pulsar leverages Apache BookKeeper as a storage component and is currently used by businesses such as MercadoLibre, Oath, One Click Retail, STICorp, TaxiStartup, Yahoo Japan Corporation, and Zhaopin.com.

Vue.js is a progressive framework for building user interfaces. Unlike other heavyweight frames, Vue uses a bottom-up incremental design. Vue’s core library focuses only on the view layer and is very easy to learn, making it easy to integrate with other libraries or existing projects. On the other hand, Vue is fully capable of driving complex single-page applications developed with single file components and libraries supported by the Vue ecosystem.

The goal of Vue.js is to implement data binding and combined view components for responses through the simplest possible API.

Vue.js itself is not a versatile framework – it only focuses on the view layer. So it’s very easy to learn and very easy to integrate with other libraries or existing projects. On the other hand, Vue.js is also perfect for driving complex single-page applications when used with related tools and support libraries.

Spring Cloud Alibaba


Spring Cloud is a framework developed by the Spring community based on Spring Boot for quickly building distributed systems. It is a microservices specification, not a ready-to-use framework, and Spring Cloud Alibaba is open source for developers. Provides an implementation of this set of specifications. At the same time, Spring Cloud Alibaba’s complete micro-service components, Chinese documentation and localized open source services increase the speed at which developers access microservices and reduce the difficulty of subsequent operations.

After more than a year of incubation, Spring Cloud Alibaba, the only domestic open source project in the Spring community, officially graduated from the Spring Cloud Incubator incubator and released a new version that is compatible with Spring Cloud Edgware, Finchley, and Greenwich.

Spring Cloud Alibaba is the first and only domestic open source project in the Spring community.

Here are just a few great projects that have entered the international open source organization and have not only served the people of the country. In addition, there are many excellent domestic open source projects that are frequently used in our daily work to help us do our work more efficiently, such as Arthas, Dubbo, Apollo, ECharts… and so on. Although these do not enter these high-level international organizations, their defenders and contributors are still worthy of respect for each of our peers, especially when the domestic open source atmosphere is not so good. However, I believe that with so many excellent projects, more and more Chinese open source will be on the international stage!
