Why does everyone say that OceanBase4.0 has opened a new milestone for domestic databases?

OceanBase 4.0 re-examines the most basic design of database and distributed system, and newly introduces the industry's first stand-alone distributed integration architecture. In the stand-alone deployment, the adaptive log flow technology will only trigger one log flow, and the user operation does not need distributed transactions and does not lose performance. When distributed deployment is needed, adaptive log stream technology will trigger a dedicated log stream for each machine. Realize the automatic expansion of multi-machine performance. It can be said that OceanBase 4.0 breaks the impossibility of distributed technology and realizes the first single-machine distributed architecture, which can really be used like a single-machine database.

In view of this situation, a group of people gave up their high-paying jobs in big Internet companies from the beginning, and made one breakthrough after another after more than ten years of deep cultivation in distributed databases. Create a native distributed database from 0 to 1, adhere to independent research and development, adhere to long-term and openness, and fundamentally solve the problem of massive data management. 12 years later, OceanBase4.0 has been polished by a large number of business scenarios, and products are constantly selected, which greatly reduces the use cost and makes deployment more convenient. OceanBase4.0 has opened a new milestone for domestic databases. It can be distributed on a single machine, but it can be large or small. Like Naruto, it can be combined or dispersed.

Ten years' accumulation: a review of the development of offshore bases

In the era of science and technology internet, chips and operating systems are well-known technical peaks, while the public does not have a deep understanding of database because of its difficult concept. In fact, the database plays an important role in our production and life. From the bank to the small supermarket around us, we can't store the information of every commodity without the support of the database. The databases of domestic enterprises mostly adopt the traditional relational databases of foreign Oracle and IBM, and only Oracle accounts for more than 50% of the global market. According to the 35 technologies that restrict China's industrial development published by Science and Technology Daily, database management system ranks among them, which shows that database is also one of the technologies that need to be solved urgently in China.

Second, it has been distributed. It appears to deal with a large number of business scenarios.

Facing the era of data explosion, database is the core foundation to realize mass data management. The appearance of distributed database represented by OceanBase has a strong background of the times. First of all, the data demand encourages upgrading, and the growth of data volume and the change of data form brought by mobile payment and big data require the bottom layer of the database to be able to handle the new technology of replacing and upgrading. With the expansion of domestic information terminals and the high coverage of online shopping, it provides fertile soil for the development of databases, which requires the database to have the ability to handle massive business. It is also worth mentioning that all regulators and policy makers focus on the distributed transformation of databases and users in key industries with application innovation strategies, so as to gradually enhance their awareness of database application innovation and guard against potential security risks, which further marks the sustained growth of the distributed database industry.

Third, today's single-machine distributed integration architecture leads the industry development.

The strong technical strength of a product is an indispensable support, but ultimately it should be customer-oriented. Oceanbase4.0 has truly achieved a comprehensive breakthrough in stand-alone performance, flexibility, cost and fault recovery. It can be said that OceanBase4.0 has opened a new milestone for domestic databases. It can be deployed on a single machine, distributed, large or small, and can be expanded and contracted.

The strong technical strength of a product is an indispensable support, but ultimately it should be customer-oriented. A major feature of our country is that there are many small and medium-sized enterprises. In view of this situation, small and medium-sized enterprises are very convenient and flexible to deploy because of their characteristics of single machine, distribution, size and combination. In the past, the traditional distributed database often needed to pay a lot of extra cost to realize distributed characteristics, which greatly reduced the function and performance of the business when it only needed to be deployed on a single machine. Typical scenarios, such as when the data modified by business only involves a single machine, still need to pay the overhead of distributed transactions, resulting in low overall performance. Or it can't support large-value transactions, and the business usage scenarios are limited.

Compared with foreign databases such as oracle, there is no great technological innovation, and there will be no overtaking in corners. The greatest contribution: it is becoming more and more common. Don't underestimate the word "average", which represents a company's technical ability, quality system and service ability have reached a high level. It can also gradually serve some core businesses in various industries. To sum up, China people in this field are on the road. Technically speaking, this does not mean that domestic databases must be far behind. The focus of domestic databases is to serve important domestic customers first, and then to occupy the market of foreign databases, so as to have the initiative and the right to speak. What stage is it now? Just like in the past, domestic mobile phones are gradually catching up with foreign mobile phone manufacturers. Now, you can use millet first. I have been in Japan for a long time.

The cost is 50-70% lower than the traditional database, which greatly reduces the replacement cost of small and medium-sized enterprises. In recent years, with the rapid development of digital economy, small and medium-sized enterprises urgently need digital transformation. How to reduce the cost in the process of digitalization is not only an important issue that small and medium-sized enterprises need to consider, but also the goal that OceanBase strives to achieve. Based on the high compression engine of LSM tree, OceanBase 4.0 can reduce the storage cost by 70%-90%; Taking Alipay as an example, after replacing Oracle database with OceanBase native distributed database, the single copy data can reach 1/7 of Oracle's, and its computing resource investment is also reduced to the original112. Compared with Oracle, only one item is stored, which saves about 2 billion yuan in storage cost, equivalent to 90% of the cost of each account.

This is the first time to reduce the recovery time from 30 seconds to 8 seconds. Today's data centers have strict requirements for business continuity, but failures are often inevitable. In case of failure, the backup mechanism should be started to ensure business continuity. Implementation of RTO in OceanBase4.0
