"We hope to open up the rich experience Alibaba Cloud has accumulated in cloud-native distributed database technology through standard technical components and systems to build an open source database ecosystem." said Li Feifei, head of Alibaba Cloud's Intelligent Database Product Division.

Database is a rigid demand in basic software, and is listed as the "three global technologies" alongside chips and operating systems. The open source model is widely welcomed by database users and is considered the standard configuration of the Internet scene.

In more than ten years, Alibaba's database has completed the development path from commercial, open source to self-research, and has rapidly formed a mountain and river. Its market share ranks , the first in the Asia-Pacific, and is far ahead of in China. Since 2018, Ali cloud database for three consecutive years to enter Gartner Database Magic Quadrant, and 2020 entered in Gartner global database Leaders Quadrant , become A Chinese company that has entered the leader in the field of basic software for the first time represents a truly world-class Chinese database.

In order to meet the diverse needs of users on the cloud, PolarDB has developed different compatible versions for different database protocols, including versions compatible with MySQL, PostgreSQL and Oracle, and the distributed form of each version. The first open source is PolarDB for PostgreSQL distributed version compatible with PostgreSQL protocol. includes database kernel, related plug-ins, tool scripts, test cases and design documents, and is suitable for core business scenarios of medium and large enterprises. This open source follows the Apache Version 2.0 protocol, and is open sourced in a mode of full sharing and respect for the original author's copyright. The code can be modified and republished. At present, the high-availability cluster version based on Paxos replication has been released on Github, and capabilities such as distributed transactions, high availability, and single-machine high performance will be introduced in the future.

​

" We have always maintained close communication with the open source community. In the future, Alibaba Cloud will also establish its own open source community to solve more business problems and needs with a faster response speed. " Li Fei, 160c309fb20989 Alibaba Cloud will increase investment in the open source database community, work with partners and developers to build an ecosystem, prosper the distributed database ecosystem, and promote technological change.
