About the Conference

Also known as the Asia’s largest open source relational database ecology conference

PostgresConf.CN and PGConf.Asia were hosted together as one conference online for the first time back in 2020. In 2021, both conferences joined forces again to deliver another successful conference that attracted record high numbers of PG enthusiasts from the world!

PostgresConf.CN is an annual conference held by the China PostgreSQL Association for PostgreSQL users and developers. It is also one of the conference series held by PostgresConf Organization. PostgreConf.CN 2019 took place in Beijing, it was very well attended by PostgreSQL users and community members across the globe.

PGCONF.Asia is also an annual PostgreSQL event that took place in Bali Indonesia in 2019, it was a continuation of the PGCONF.Asia event that took place in Tokyo, Japan in 2018. The first PGCONG.Asia conference took place in 2016 in Tokyo, this conference acts as a hub of PostgreSQL related development and technical discussion among PostgreSQL users and developers in the region as well as experts from around the globe.

Conference Highlights

Opening Speech by Fellow Guangnan Ni

Guangnan Ni first expressed his warm congratulations to the holding of the PGConf.Asia 2021 Asia Conference, and greeted sincerely to the representatives of various countries and open source experts participating in the conference. He pointed out that open source is an important trend in the development of today’s world, and open source technology is profoundly changing the global digital economy and information industry pattern. The holding of this PG Asia Conference is of great significance to the development of the open source industry, the promotion of the open source movement and the popularization of open source culture in China, and the strengthening of international exchanges and cooperation.

Bruce Momjian

Bruce Momjian, as a core group member of the PG international community, has always been keen on sharing themes in the community. This time Bruce made a sharing based on the status quo of PG, project development challenges, competition challenges, and technical challenges, mainly emphasizing that the development process of the PG version has been adapting. Changes in the environment, continuous breakthroughs and innovations, such as SSD optimization, virtualization, containerization, and functional expansion of cloud environments have been completed in the face of technical challenges. For the future evolution of the PG version, it will continue to optimize and iterate on several aspects such as PG write amplification, TDE encryption, and horizontal scalability.

Peter Zaitsev

Mr. Peter Zaitsev, CEO of Percona, has been a guest at the PG Asia Conference for the second time. This time Peter brought us a speech of “State of Open Source Databases”, mainly from cloud computing, PG peripheral ecology, DaaS and K8S. This aspect expresses the openness and flexibility of PG, which enables PG and the evolution of the technical architecture to be better integrated, promote mutual development, and meet the needs of different business scenarios. He said that Percona, which has been engaged in open source database services for many years, loves to embrace PG and make innovations based on PG to bring more value to customers.

Chunxiao Xing

Professor Xing Chunxiao, deputy dean of the Institute of Information Technology of Tsinghua University and deputy director of the Information System Committee of the China Computer Federation, shared with us the most popular topics of “metaverse”, blockchain, and data lake, emphasizing that data management is a popular technology development Only the continuous evolution and iteration of database management software can better provide support for cutting-edge technologies and make our lives more meaningful.

Zhiming Ding

The ivorySQL project is a PG open source derivative project with a broad ecological foundation and Chinese characteristics. Its purpose is to develop community collaboration among Chinese developers and allow engineers to create greater personal and social value.

The session was presented by Professor Ding Zhiming, an early promoter of research practice in the domestic PG field, the new president of the China PG branch, and director of the Center for Space-Time Data Science (STDMS) of the Chinese Academy of Sciences. Their system completely expounds the necessity and realization idea of “PostgreSQL database software + Chinese characteristics”, the positioning, characteristics and operation mode of the ivorySQL project and community. Through the launch event, the project was officially known to the majority of PG practitioners in China.

The launch of IvorySQL attracted many domestic PG enthusiasts, and they have provided suggestions and opinions to make the project better. We feel very thankful for their effort into this new project. In the mean time, please check out the project’s official website at www.ivorysql.org for the latest developments.

Xiaojun Zheng

Xiaojun Zheng, Chief Scientist of HighGo, presented “Highgo peer-to-peer service cluster database”.

Mr. Zheng first gave a systematic overview of the definition of database cluster, and then explained the concept and implementation of “peer-to-peer service cluster” in a more generalized manner. Finally, Mr. Zheng led everyone to experience Higao’s Peer-to-peer service cluster database environment. Through this practical demonstration, we have brought you a new idea and method for realizing peer-to-peer service clustering. Architects and product managers who pay attention to the PostgreSQL database, I believe they can gain new product inspiration from it.
