Recent years , In the field of Industrial Science and technology , More and more Chinese enterprises like ideal have abandoned the traditional “ Overtaking in curve ” Strategy , Have chosen to open a new track “ Lane change overtaking ”. among “ User experience first ” Not only is it ideal to make a distinction mark , It is also the direction that enterprises in other industries have been exploring , Try to open up your own advantage track . for example , Databases that play a key role in the field of basic software .

We know , In technology manufacturing , The smooth and efficient operation of the production line is the lifeline of the enterprise . If the core production line execution system fails , It will directly lead to shutdown , Every second means supply chain and manpower 、 resources 、 Huge loss of opportunity cost , It can even set off the butterfly effect .

Imagine such a scene :  In a tight production lead time , One day, the production line system suddenly experienced a request timeout for a certain flow link , Material pulling and scheduling are affected , It is preliminarily confirmed that the database load is full , As a fireman DBA Open the slow log to start analysis , Looking at the full screen SQL Execution list ： Time consuming 、 Number of executions , The various indicators of the implementation plan are related to each other , Unable to quickly determine the root cause …… Under great pressure ,DBA Start killing connections in an attempt to restore the system , But the speed of connection killing can not catch up with the speed of automatic retry by the application system ……

Final , The R & D team rolled back the release of new system functions , The system is restored after performing a lossy downgrade , The production impact is irreparable . A sense of powerlessness surged into my mind , As SRE We all know , There was another bloodbath at the fault recovery meeting .

This year, , Ideal auto self research MES Manufacturing systems 、WMS Warehouse management systems are used OceanBase 3.0 edition . Under the escort of intelligent operation and maintenance system , abnormal SQL The diagnosis of is real-time automatic analysis ,DBA Just take a look at the suspicious at the critical moment SQL list , Can quickly determine the root cause of the problem , And get reasonable emergency optimization suggestions . And this is just a self-study OceanBase A miniature of intelligence .

All self-developed ： All in order to go further

last year , At home L2 The level of auxiliary driving passenger cars has reached 22.2% Market penetration of , And the ideal is in the higher L3 even to the extent that L4 On the evolution road of assisted driving , We have chosen the self-study route that is completely under our own control . In addition, the extended range system 、 Chassis control system , The central domain controller is also independently developed . As a new force , But it has reached the forefront of the industry . This insight and strategy is similar to OceanBase Persistent “ from 0 Build the next generation database ” agree without prior without previous consultation . Use existing solution products to transform , May go faster in a short time , But complete independent research and development , To go further in the future .

Take a specific example ：OceanBase Based on Paxos The protocol implements the database service “ Automatic fault recovery ” and “ Zero data loss ”, And maintain stable performance and availability even under complex network conditions . As a consensus agreement “ origin ”、 The best fault tolerance Paxos, Its engineering implementation is also the most difficult . This is also adopted by many products in the industry Raft The reason for the simplified algorithm . Through the continuous efforts of the kernel Engineers ,OceanBase As early as 1.0 The version implements a complete and independent implementation based on Multi-Paxos Log synchronization mechanism of the algorithm , And in the extreme scene, polish the... Which has been iterated for many years 3.0 edition , This is also for OceanBase Supporting the long distance across the city “ Live more ” The deployment architecture provides a solid foundation .

Migrate to OceanBase after , The average jitter frequency of an ideal production line execution system database decreases by about 80%, For common fault events, we have really achieved “ Recover first , Post analysis ”. this , This is the meaning of self-study .

OceanBase be based on Multi-Paxos Basic architecture

Today, OceanBase Intelligent operation and maintenance system , Around monitoring 、 The diagnosis 、 Report on three dimensions , It provides users with rich functions 、 Easy to use “ Powerful weapons ”, Now let's introduce .

Intelligent monitoring

The monitoring system of traditional database , Users are often required to find indicators that may be abnormal in the numerous monitoring items , And the correlation and causal analysis between the various indicators , In fact, it relies heavily on expert experience .

OceanBase Operation and maintenance management tools  OCP, Embed expert experience directly into each layer of monitoring , Response from the surface RT Drill down to the basic index of a single physical node , Users only need to click the associated suspicious indicators in each layer of monitoring , We can position the problem layer by layer . Say goodbye to the past “ Open a dozen monitoring pages at the same time , Repeated comparative analysis ” Inefficient troubleshooting .

Besides ,OCP Intelligent monitoring can also support from “ The alarm -> monitor -> Business -> SQL -> Trace ” Correlation analysis of the whole link , Help users locate problems more quickly .

Intelligent diagnosis

More slowly than most others SQL Monitoring based database diagnostic products , new OCP 3.3 In the version , Intelligent diagnosis has evolved to a new level . Not only does it support the suspicions mentioned earlier SQL Automatic analysis , It also provides services such as transaction diagnostics 、SQL Request analysis 、SQL Executive portrait 、 Intelligent optimization suggestions 、 Deadlock analysis and other rich functions , Greatly improve the understanding of “ abnormal SQL” The processing capacity and emergency response efficiency of the biggest culprit behind the abnormal events in this database ：

Big transaction analysis and diagnosis ： Effectively intervene in pending or long transactions , Avoid business congestion ：

SQL Request analysis ： Visually display all kinds of time-consuming data in the current database SQL Distribution of execution times of 、 Response time distribution ：

SQL Perform portrait analysis ： OceanBase As a HTAP database , With Parallel The complexity of pattern execution SQL Can be clearly analyzed through the portrait ：

Users can even intuitively see the most time-consuming operator in the physical execution plan in the form of a flame diagram ：

SQL Optimization Suggestions ： Provide recommendations for optimal index creation directly 、 Recommendations such as historical optimal plan recommendations and tenant specification expansion recommendations , The operability is very strong , In a large number of scenarios, users only need to perform optimization operations according to the recommendations to quickly solve problems .
