Ding Zhiming, director of space-time data Science Research Center (STDMs) of Chinese Academy of Sciences and President of China PostgreSQL Association, has the theme of "PG ecological development under the wave of open source"。In his speech, he shared the development of open source in China, the advantages of PG ecological development, how to govern the PG community, and reviewed the contributions made by Chinese open source developers in the PG version; In particular, as an active community organization in China, China PostgreSQL Association's work policy in governing the community is to cooperate with national universities, scientific research institutions, enterprise users and open source communities to improve PG China's open source community organization; Standardize and guide more PG open source enthusiasts to participate and contribute, develop and activate PG China open source community, and show China's open source strength to the world.
The next step is the release of the ivorysql project. Ivorysql project is a PG open source derivative project with broad ecological foundation and Chinese characteristics. Its purpose is to develop the community cooperation of Chinese developers and let engineers create greater personal and social value.
This session was organized by the early promoter of domestic PG research and practice, the new president of China PostgreSQL Association, director of Research Center of spatiotemporal data science of Chinese Academy of Sciences Professor Ding Zhiming,, presided over by Mr. Zheng Xiaojun, chief scientist of Highgo Database, and Mr. LV Haibo, chief researcher of MeiChuang Technology. They systematically and completely expounded the necessity and implementation ideas of "PostgreSQL database software + Chinese characteristics", as well as the positioning, characteristics and operation mode of ivorysql project and community. Through the release activities, the project was officially launched in China Known to the majority of PG practitioners.
Then came the release ceremony of PostgreSQL China technology selection in 2021
Awards were given to the six awards of "best database product", "China's best service provider", "best innovative enterprise", "best application case", "China's best server solution" and "China's best domestic operating system solution".
Subsequently, the 2021 China PG ACE selection and release ceremony was held,
A total of 10 PG ACE Partners, 11 PG ACE and 2 PG ACE Directors were selected this year. The specific selection results are shown below or go to www.postgresqlchina.com (New PG ace members will be launched later)
Then came the keynote speech of "ecological evolution and technical architecture sharing of Tencent cloud PostgreSQL" by Dr. Liu Shaorong, head of Tencent Cloud database technology expert group
In her speech, Dr. Liu introduced the advantages of Tencent cloud PostgreSQL, the distributed transaction processing capability, security (separation of powers, data desensitization, etc.), OLAP and parallel processing capability, Oracle syntax compatibility and read-write separation function of Tencent cloud enterprise distributed database TDSQL-PG (original TBase).
Dr. Liu explained the architecture of TDSQL PG and the efficient and scalable distributed transaction design in detail. She also introduced the distributed analytical database TDSQL-A developed by Tencent. TDSQL-A provides 100% PostgreSQL compatibility, and has row and column mixed storage, multi-level compression of column data, vectorized execution engine, multiple parallel execution policies, CBO,Distributed delay materialization optimization and other core technologies developed by Tencent.
In this speech, Dr. Liu focused on TDSQL-C PostgreSQL, a Tencent Cloud native distributed database, which is a completely self-developed cloud native database. Based on the design idea of separation of storage and computing and log as database, it integrates the advantages of traditional database, cloud computing and new hardware technology, and has high availability, high reliability, high performance and extreme flexibility, It has fast recovery function, adopts lock free design, reduces kernel switching, 100% PostgreSQL compatibility and is highly compatible with Oracle. In particular, TDSQL-C PostgreSQL has deleted the full page write function in the native PostgreSQL database. In terms of changing the FPW function, this is actually a functional improvement that tests the control ability of the PostgreSQL database kernel. From this improvement, Tencent Cloud database team has a high control ability of the PostgreSQL database kernel.
Finally, Dr. Liu made a prospect for the future of Tencent Cloud PostgreSQL from four aspects: ecology, cloud native architecture speech, new hardware and intelligence.
Zheng Xiaojun, chief scientist of Highgo Database, brought us < < Highgo's peer-to-peer service cluster database > >
As a well-known PostgreSQL database technology provider in China, Highgo has a R & D team proficient in database kernel, a product team proficient in database product line and a technical support team with rich practical experience. Highgo has been in the field of peer-to-peer server cluster for a long time, has invested a lot of resources in special research, and has accumulated rich technical experience. Based on the technical precipitation of these research, Highgo has formed a cluster product family with high efficiency, good stability, easy expansion and manageability. Let's review Mr. Zheng Xiaojun's sharing.
Mr. Zheng Xiaojun first gave a systematic overview of the definition of database cluster, and then popularized the concept and implementation of "peer-to-peer service cluster". Finally, Mr. Zheng Xiaojun led you to experience the database environment of Highgo peer-to-peer service cluster through operation demonstration. Through this practical operation, we have brought a new idea and method to realize peer-to-peer service cluster. Architects and product managers who pay attention to PostgreSQL database can gain new product inspiration.
