Motianlun domestic database rankings in June 2021: OceanBase, PolarDB join forces with TiDB, openGauss, enter the open source camp, and compete for ecological construction

"The first summer is still peaceful, and the grass has not stopped." By June, the domestic database market, where a hundred flowers blossomed and a hundred schools of thought contended, continued to be as hot as the sun. But from the latest issue of the ink sheave domestic database popularity ranking is not difficult to find in the Top 10, a word enough to become the focus of attention, and that is "open source" ! In the past week, PolarDB and OceanBase have announced open source. So far, the top three "TOP" have joined the open source camp, including openGauss, there are four of the top ten, and the big open source era of databases is coming to us.

Looking specifically at the rankings and scores of the top ten in this issue, the results of open source databases are undoubtedly the most eye-catching. First, openGauss jumped two places to the sixth place with a single month increase of 64.75 points , squeezing the same elder brother GaussDB and Goose Factory's TDSQL respectively to the next place; secondly, PolarDB is not to be outdone. Although the ranking has not changed, it is 55.27. The increase in points was enough to keep it firmly in the top three positions, and the difference with the fourth place Dameng from 35 points last month to 132 points now; finally, Ocean Base 's slight increase (see below) and The decline in TiDB narrowed the difference between the two to nearly 100 points. These two popular databases, which are similar in types, have large overlap in applicable scenarios, and are based on the financial industry, are bound to compete for the top spot in the second half of this year.

The rankings of other databases in the top ten have not changed, and the scores have fallen more or less. The author inferred that the market volume of these databases has decreased in May, and the open source database has become so strong. The superposition of two factors has caused the weighted average to be pulled up.

Looking at the 11th to 15th places, Kingbase, EsgynDB and TcaplusDB all performed well, achieving different degrees of increase in points. EsgynDB and TcaplusDB jumped by two places to the 12th and 15th places respectively; while Kingbase has not changed its ranking, but achieved the only positive growth among the "traditional four old companies", and the gap with GoldenDB, the 10th place, has narrowed to only 4 points. , The goal is to be among the top ten.

OceanBase, which adheres to the road of self-research and openness, is officially open source

The news that OceanBase will open source has long been rumored in the industry, and all the suspense was announced at the "OceanBase 3.0 Database Summit" held on June 1 . At this summit, OceanBase, a distributed database independently developed by Ant Group, systematically expounded the future development strategy from the three dimensions of technology, business and ecology for the first time. At the same time, OceanBase announced the official open source and established the OceanBase open source community. The official website of the community was launched simultaneously, and 3 million lines of core code were opened to the community.

It is understood that open source has risen to an important technology strategy for OceanBase. The open source uses Mulan Public Agreement MulanPubL-2.0 version, and the industry's common Open Core model. The open source range includes database kernel, distributed components and interface drivers, and provides a complete SQL engine, transaction engine, and storage engine, supporting multiple copies, distributed transactions, high performance, scalability, failure recovery, optimizers, and multi-active disaster recovery , Grammatical compatibility and other core technologies. Yang Zhenkun, the founder of OceanBase database, said that OceanBase is committed to building an enterprise-level open source database. At the same time, it works closely with partners to quickly release commercial versions to meet industry customers' business demands for high-performance, high-reliability, and integrated processing of databases. Interested friends can go to the OceanBase open source official website to view and experience more details.

Although OceanBase has only slightly increased by 0.72 points in the rankings updated this month, with the "6.1" conference, concentrated reports on related information, the establishment of open source communities, and more people's attention, I believe OceanBase is next There will be dazzling performance in the monthly updated rankings.

The open source Alibaba Cloud database wants to create a cloud-native distributed database ecosystem

At the "2021 Alibaba Cloud Developers Conference" held on May 29, Li Feifei (nickname: Feida), the head of Alibaba Cloud's Intelligent Database Product Division, conducted "Cloud Native Database 2.0: One-stop Data Management and Service" Keynote speech. At the end of the speech, Fei Dao announced the Alibaba Cloud database open source plan, working with the open source community to build a cloud-native distributed database ecosystem.

Alibaba Cloud, as a domestic cloud-native database technology leader, has become the first open source cloud-native database organization, giving back to the industry and the majority of technology enthusiasts. According to the announced plan:

  • In June 2021, the open source enterprise-level distributed database PolarDB for PostgreSQL, the first step is to release the Paxos high-availability cluster version in June, the HLC high-scalability distributed version in September, and the Sharding and plug-in versions in March next year.
  • In October 2021, the open source cloud-native MySQL database ApsaraDB GalaxySQL will first release the cluster version based on Paxos high availability in October, and the cloud-native distributed version will be released in June next year.

Alibaba Cloud has rich practical experience in its own Internet business and cloud database services, and has deep accumulation in high-availability, distributed, cloud-native, and separation of storage and computing technologies. Today, Alibaba Cloud integrates these key technical components and systems, including the internal MySQL branch AliSQL (the core of the current RDS service), the distributed consistency protocol library X-Paxos, the cost-effective storage engine X-Engine, and the distributed database product PolarDB for PostgreSQL Open source together can create more system solutions, thereby continuously improving and enriching the form of cloud-native distributed databases, meeting more diverse user needs, and further promoting the transformation of the entire database industry.

Feida also announced the GitHub address of PolarDB for PostgreSQL for the first time . Interested students can directly pull to the local experience.

Ecologically prosperous openGauss continues to build enterprise-level core capabilities

Ecology is a key factor in the success of open source library databases. openGauss has always adhered to the ecological strategy of co-construction, co-governance, and sharing, and cooperates with industry chain partners to ultimately achieve a win-win ecosystem.

On the "OSCAR Open Source Pioneer Day" on May 26, the " Trusted Open Source Community Evaluation System" standard led by China Academy of Information and Communications Technology and dozens of well-known companies in the industry was formally released. This standard sorts out the content and indicators that should be paid attention to in the development and governance of the open source community, and lays the foundation for the safe, healthy and sustainable development of the open source community. openGauss has been reviewed and tested by OSCAR experts in 22 stages and became the first batch of "trusted open source communities" to be evaluated . Three days later, the openGauss Meetup [Beijing Station] was successfully held at the Zhongguancun Intelligent Manufacturing Innovation Center in Beijing, attracting extensive participation in the entire ecological chain of "production, study, research and application". The openGauss Beijing City User Group was also established.

It can be said that since openGauss has been open source for nearly a year, the community has grown rapidly and the ecology has flourished. It has continued to strengthen around enterprise-level performance, enterprise-level security, and enterprise-level reliability, and has accelerated its landing in the industry. At present, openGauss has successfully supported the launch of the new generation of distributed financial core system of Postal Savings Bank of China and successfully built a leading financial core system in the industry; helped the China Life Group Insurance core system use Kunpeng full-stack replacement to achieve performance doubling; openGauss is based on Kunpeng 4-way server China Mobile's database performance test ranking is absolutely leading. Facing the future, openGauss will continue to make breakthroughs in core technologies from the most urgent problems and long-term needs of database applications in the national economy and people's livelihood industry, and will deepen its roots to jointly create a lush mainstream database ecology.

Open source pioneer TiDB already has complete HTAP capabilities

This article focuses on "open source", so when it comes to open source databases, you have to mention PingCAP's TiDB. Since its birth, TiDB has implemented distributed clusters in an open source version. For users, the value enhancement it brings is very high. Because of this, PingCAP, which was founded 6 years ago, has accumulated more than 1,500 users in industries such as finance, operators, and the Internet. TiDB is not only an excellent database product, it has also become the basic support for the development and growth of the entire TiDB community.

I still remember that when TiDB 5.0 was released more than a month ago, one of the keywords emphasized was "practice internal skills." From 4.0 to 5.0, there are not many new TiDB functions that focus on the continuous optimization of stability and performance, and these are precisely the capabilities that a true enterprise-level database should pursue.

Nowadays, with the continuous emergence of business scenarios with integrated SQL and NoSQL requirements, the hybrid load HTAP database has become a key technology that has received more and more attention in the IT industry. TiDB 5.0 introduces the MPP architecture on the basis of TiFlash, which functionally completes the last piece of HTAP's puzzle, provides a distributed computing engine that matches the storage, and further improves the parallel computing and analysis capabilities under massive data. This indicates that TiDB has become a HTAP distributed database with complete capabilities.

In the field of domestic open source databases, TiDB is a pioneer, has formed a complete community ecology, and is also relatively successful in internationalization. Now, OceanBase and PolarDB have entered the open source camp. Together with openGauss, which was open sourced a year ago, it is bound to pose a challenge to TiDB; Healthy competition is a good thing for open source databases and the entire database industry.

Open source has become an important force in the construction of database ecology

In contrast to closed-source commercial databases, open-source databases are free community databases whose source codes are open to the outside world, and developers can modify or use them on the basis of their original designs. It provides corresponding solutions for increasingly complex enterprise needs with low cost, rich products and active community support. Judging from the ranking scores of DB-Engines, the popularity of open source databases has increased year by year, surpassing commercial databases for the first time in January this year. The open source momentum is so fierce, and the reason behind it is the dispute over the construction of the database ecology.

The current database ecology can be roughly classified into three categories: one is traditional commercial databases, represented by Oracle, whose database empire created in more than 40 years has an extremely complete ecology; the other is open source databases, represented by MySQL and PostgreSQL , Community organizations all over the world have formed a strong ecosystem, and have formed several branches, which have achieved many commercial database products; the third is domestic emerging databases, represented by TiDB, OceanBase, PolarDB, etc., with strong self-research Ability, but it is much weaker than the previous two types in terms of ecology. How to quickly establish and form an ecosystem in line with one's own interests? Open source is undoubtedly an excellent choice.

The author noticed that whether it is TiDB, OceanBase, PolarDB, or openGauss, they all chose the relatively loose Permissive License. This kind of open source agreement allows the code to be closed after modification, so it is more favored by commercial companies. Here we have to mention the business logic of open source-the continuous development of open source depends on continuous technological innovation and a virtuous circle of business. With the help of open source, product innovation and iterative evolution can be accelerated at the technical level-"software is used instead of made". Open source gathers the wisdom of everyone, promotes product use, continuously optimizes functions and performance, and quickly forms competitiveness ; At the commercial level, relying on open source to form functional enhancements, after-sales support, market education, talent training, supporting tools, brand influence, etc., can directly or indirectly generate economic benefits, thereby promoting the growth of the developer community and the production of more technological innovations. Get a strategic position that is beneficial to you.

Therefore, this also explains why large companies have entered the construction of an open source ecosystem. Today, as TiDB, OceanBase, PorlaDB, openGuass, etc. have joined the open source camp, I believe that in the future, the emerging domestic database ecosystem will grow rapidly and thrive, and it will also drive the development of the entire domestic database industry.

Demonstrate their abilities and promote the vigorous development of the domestic database industry

Compared with the popularity of the open source camp, some domestic database vendors seem a little low-key. In fact, this is just a different business model or business focus. Closed-source database products are also worthy of attention. On May 10, Deben Consulting/eNet Research Institute/Internet Weekly published the "2021 Xinchuang Database Enterprise Ranking" . 15 database companies were on the list. Dameng Database ranked first with an advantage of 0.02 points, followed by The other three traditional database vendors: National People's University Jincang, Nanda General Motors and Shenzhou General Motors, with Jusen Database ranked fifth.

According to data from the Haiby Research Institute, the scale of my country's Xinchuang ecological market in 2020 will be 161.7 billion yuan, and it will maintain rapid growth in the next five years, with a compound annual growth rate of 37.4%, and will reach 800 billion yuan in 2025. Through continuous development, Xinchuang can become a breakthrough force to reshape the traditional pattern of China's informatization and digitalization market that emphasizes applications and neglects technology, and urges it to enter the technology-driven market. Among them, the database as the basic software is the backbone of technology-driven.

This issue of the database popularity rankings has included 131 domestic database products. Regardless of their scale and ranking, everyone is contributing their strength to the vigorous development of the domestic database industry. Due to space limitations, the author will not list the memorabilia and important product release news of the domestic database in May. The editor of Mo Tianlun has compiled it for everyone.
