How to resolve the 35 year old crisis? Sharing of 20 years' technical experience of chief architect of Huawei cloud database

Abstract ： Face the so-called 35 Age crisis , Feng Ke emphasized that the most important thing is to have accumulation and analysis .

This article is shared from Huawei cloud community 《 Dry cargo is full. ！ Chief architect of Huawei cloud database 20 Years of technical experience sharing , How to dissolve 35 Age crisis 》, author ： Huawei cloud community selection .

The database carries the most critical data of customers , It needs to have very good usability , reliability , Therefore, it is also a great test of the development ability of a kernel team , The ability to produce , And the ability of the project to land .

And developers in every database field , Perhaps they have experienced the subversive push of the database kernel and start over again ; Rewrite the storage and transaction engine of the entire database ……

stay 《 Yunxiang character · On the other side of the cafe 》 Issue 5 In an interview , Huawei database scientists 、 Huawei cloud database GaussDB Feng Ke, the chief architect, shared his thoughts on industry and Technology . meanwhile , Count the technical challenges encountered over the years , He also summed up his own methodology .

How to overcome technical problems ？

The first is to grasp the panorama of the problem as much as possible .  Understand how others solve similar problems , Their success and failure stories , Stand on the shoulders of our predecessors , Clarify your understanding of technical products , Constantly review and reflect . Even if the same person is facing the same problem , At different stages of life , The ways and practices of solving problems are also very different .

The second is to understand the details .  Regardless of personal qualifications , No matter how cool the idea sounds , Be a new database engine , You still need to drill down into the code , Sink yourself into the details , Your idea can finally come to fruition .

Finally, learn to choose .  When starting architecture design , Clearly know what is good and bad , But we still have to face it soberly N Maybe , And make the right balance .

Standing on the 35 The crossroads of age , Where are the older farmers going ？

Stick to the front line of technology 20 Many years later , For Feng ke , My life has been connected with the database “ inosculate as a whole ” 了 , He also takes himself as an example , Shared  “ Older technical code farmers ” Experience of transformation .

According to the type of business , Databases can usually be divided into three types .

• One is OLTP, Mainly dealing with business , Emphasize efficiency ;
• One is OLAP, Analyze these transactional data , Emphasize the accuracy of analysis and decision-making .
• And two mixed states ：HTAP.

As a highly discussed programmer in the industry “35 Middle age crisis ” For boundaries , Feng Ke said , stay 35 Before the age of , Technology developers usually do OLTP Things about ,  Improve code capability and efficiency , Work fast and well . When it comes to 35 After the age of , Maybe personal code ability will not increase any more , Transaction processing capacity has also reached its peak , At this time, we should consider transformation .

For instance from OLTP To OLAP, Become a technology manager , Internalize and precipitate their past technical experience into team experience , Help the whole team make decisions 、 Little detours .

Or from OLTP To HTAP, Continue to work on the front line , Continue coding , At the same time, have certain analysis ability , Constantly sum up from the experience of past failures , While slowing down transaction processing capacity , Improve the integrity of thinking .

therefore , Face the so-called 35 Age crisis , Feng Ke stressed that the most important thing is to have Accumulate and analyze precipitation ,“ If there is no accumulation ,35 Years old may really become a crisis ”. Of course ,“ Although experience is wealth , But it can also be your bottleneck 、 Your Siege , Especially for Technology Managers , Be sure to study all your life , Avoid personal experience becoming the ceiling of team development .”

Practical experience sharing , How to keep lifelong learning

Last , Feng Ke started from the experience of the database team he led , They talked about how they maintain the state of lifelong learning ：

1、 See at least 10000 lines of code every year , And repeat the details of the code , Everyone's work experience determines their understanding of the code , Through the thought collision of different understanding dimensions , To improve the technical ability of the team .

2、 Read the same book every month .  Whether it's a beginner 、 New people without any experience , There are still experienced old people , Read a book together , Share reading insights with each other .

Feng Kexin , Interest in code , Curiosity about new things , It is enough to support their long-term focus and enthusiasm on basic software technology such as database .
