Yunhe Enmo Lecture Hall·Xiamen Station was successfully held on August 5 at the Hampton by Hilton Hotel in Xiamen City Center after being postponed due to Typhoon Dusurui. This meeting invited many senior technical experts and industry users from Yunhe Enmo to share their high-quality, efficient, and high-security construction plans and thoughts on domestic database application systems. The atmosphere of the event was warm and the exchanges were active. Let us review the exciting content of this meeting through this article.
Ou Xiaoyan, deputy general manager of the customer department of Yunhe Enmo South District, delivered a speech to express his welcome to the audience. He said that Yunhe Enmo had just experienced his 12th birthday. Diligently working in the database field, from database services to database ecological products, to joining the domestic database construction camp, has been constantly breaking through and growing. Such rapid development is also inseparable from the trust and support of many customers and partners. We hope that this event can bring you new thinking and collisions in the development of localization.

Yang Kang, a solution expert of Yunhe Enmo, took the lead in sharing a keynote speech entitled "Sure to Win, Full Lifecycle Migration Practice of Domestic Database "Selection and Management"" . He said that the current database localization replacement in various industries is often faced with three major problems: "how to choose", "how to replace" and "how to manage". The correct selection of the model is the key to the success or failure of the replacement project. Yang Kang said: "Choosing badly is like getting on the wrong boat. If you choose an inappropriate technical direction or a database product with poor sustainability, it means that a lot of subsequent adaptation and replacement work will be wasted." In this regard, he Suggestions are given: open-source and closed-source business strategies have their own advantages, select the database architecture that meets the needs of the business scenario, explore the openness and controllability of its technical origin, and then conduct a comprehensive technical index inspection and choose the best.

In the migration phase, having streamlined and standardized migration implementation steps can often speed up the replacement progress and avoid differences in database quality. Yunhe Enmo has formed a heterogeneous migration methodology of "four steps, nine steps, and twenty-eight items" after thousands of sets of heterogeneous database migration and polishing , helping users allocate resources more scientifically, ensure execution results, and make emergency plans .
At this stage, the localization of various industries is carried out in batches, and the operation and maintenance work needs to face the operation and maintenance of the multi-source and differentiated domestic environment and the integrated operation and maintenance of the old and new systems. A standardized, automated, and intelligent management method is particularly important. important. "The zCloud product, which Yunhe Enmo has been researching for nine years, can realize the full life cycle management, operation and maintenance of multi-source heterogeneous databases from installation and deployment to daily inspection, and then to problem warning and intelligent processing. A sharp tool for dimension management." Yang Kang said.
In the army of domestic databases, Yunhe Enmo is also an important member. Based on the enhancement and improvement of the openGauss kernel, the "stable and easy-to-use" enterprise-level relational database MogDB created has been available for three years. , the database R&D team of Yunhe Enmo has developed many features, which can bring users ten times performance improvement and several times space saving. Liu Xuelong, a cloud and Enmo solution expert, focused on sharing the feature upgrade of MogDB version 5.0 through a keynote speech entitled "Return to the original, MogDB relies on the independent root community's technological innovation and implementation practice" .

As a database product that combines the advantages of open source and business models, MogDB has taken the fast track of core technology development, and has developed many performance, Liu Xuelong explained the engineering improvement features in TCO, availability, and maintainability in detail with examples: asynchronous submission features of autonomous transactions, both performance and reliability, TPC-C 10~20% performance improvement; dynamic partition pruning brings big data The performance is improved by 10 times under the volume; the row-level compression of the row-storage table can bring about several times the space saving without compromising the business performance, etc. The ultra-high performance level and the professional service guarantee of Cloud and Enmo make MogDB popular with users such as banks, funds, and insurance companies who have higher requirements for high concurrency, timely response, and self-controllability. Liu Xuelong further interpreted the alternative programs and processes.
Subsequently, Chen Wu, the data center operation and maintenance manager of Sanfu Department Store, gave a keynote speech on "Preventing Micro-duration, Sanfu Department Store's SQL Audit Road to Reduce Daily Operation and Maintenance Risks" . In his speech, he said that before 21 years, Sanfu had done four or five years of post-optimization work. The workflow was to record and review hidden dangers after deployment to the production environment, and then the DBA would give suggestions to developers Modification, this working mode has the disadvantage of not being verified in advance, and the problem processing lags seriously, and waiting until the fault occurs to deal with it will often bring great losses. Until June 2021, after three failures caused by inefficient codes, Sanfu decided to introduce SQM to do SQL review beforehand.

The effect brought by the introduction of SQM is very obvious. Operation and maintenance personnel use SQM to increase the introduction of test links in the quasi-production environment, enrich the rules of the data dictionary, add SQL review rules, and use crawler technology to export corresponding statements and associate them with the deployment list Under this circumstance, the actual audit volume is reduced through intelligent identification, and it is truly identifiable and collectable. DBA can actively optimize without relying on developers, effectively improving the timely rate and completion rate of optimization, and the optimization time of each order is reduced from 41 minutes to 19 minutes, which greatly improves the operation and maintenance efficiency and solves the operation and maintenance of Sanfu Department Store work dilemma.
Chen Huoping, solution manager of Yunhe Enmo, delivered a keynote speech entitled "Stable as a Rock, zData and zDBM Work Together to Build the Foundation of the Database" . With the continuous development of science and technology, more and more emerging business scenarios are born, and the amount of data is skyrocketing. The era of mobile Internet with high concurrency and complex environments has arrived. Facility requirements. Cloud and Enmo database all-in-one machine product zData has industry-leading storage performance and flexible expansion capabilities, which can meet various database scenarios; through thread scheduling optimization, scheduling overhead is reduced, dedicated cores are dedicated, and key business delays are guaranteed; and memory access is optimized. Mechanism to reduce lock access and improve performance by 4 times; dual-mode copy optimization, flexible selection, to meet extreme delay requirements; high-speed protocol optimization, multiple performance acceleration technologies, mobilize the computing power of each chip. Help users greatly improve performance, improve business response efficiency, and be able to flexibly expand to achieve the best cost performance.

Efficient operation scenarios also require reliable backup guarantees. However, traditional backup guarantees the stability and security of steady-state systems, and it is difficult to ensure the flexibility and convenience of new business-sensitive systems, nor can it meet the data protection requirements of core databases. Cloud and Enmo self-developed zDBM, a database recovery platform based on CDM technology that helps improve data protection performance and shorten the application development cycle, integrates disaster recovery, data recovery, and data reuse scenarios, and replaces the traditional 10-hour recovery The time is shortened to minutes to ensure business continuity. It has helped many customers from key industries such as finance, medical care, government affairs, communications, manufacturing, electric power, and transportation to do a good job of security protection.
Luo Bingsen (Luoluo), Database Architect of Yunhe Enmo
If you want the database to run fast, SQL optimization is indispensable. But SQL optimization is not just about collecting statistical information, creating some indexes, and binding an execution plan. When faced with hundreds of lines of huge SQL, SQL equivalent rewriting is often required for further optimization. Luo Bingsen (Luoluo), a database architect of Yunhe Enmo who has more than ten years of experience in SQL optimization, delivered a speech on the theme of " Keep Improving, SQL Equivalence Rewrites Core Ideas" . Through actual cases, it describes different rewriting methods such as the relationship between tables, semi-join, anti-join, scalar subquery, Filter, etc. Its witty and humorous way of explaining makes the audience relax when they listen to the knowledge attentively .
In the nearly four hours of the meeting, five rich speeches basically covered the construction plan of domestic database selection and alternative management and the construction of stable and reliable peripheral applications, allowing the audience and friends present to spend a fruitful afternoon. . This year, the "Yunhe Enmo Lecture Hall" city tour lecture has gone through Wuhan , Chengdu , Shijiazhuang , and Xiamen, and will come to Shanghai on the afternoon of August 11 (click to view the Shanghai event schedule and sign up) to start the fifth stop.
