An intern CnosDB The journey

The first experience of the interview

This year, 2 One afternoon in January, I was with CnosDB The beginning of bonding , I can't remember the interview content for a long time , I only remember that pangliang asked me a question “ Can you elaborate on B+ Knowledge of trees ？” I can't answer , I told pangliang frankly ：“ teacher , I only learned B Trees , Never learned. B+ Trees .” Unexpectedly, pangliang explained it to me very patiently B+ Tree related knowledge . At that time, my mood was very complicated , On the one hand, I'm worried that if I don't answer the questions, I may fail in the interview ; On the one hand, I was surprised that pangliang told me something I couldn't know , This is something I have never encountered before . Fortunately, , Because the answers to other questions during the interview are ok , I am honored to be CnosDB The employees' . And I also found out on the day of entry , It turned out that he explained it to me patiently that day B+ The fat beam of knowledge , It's my boss .

New entry experience

The experience of joining a new company is very novel , It is very different from other internship and project experience before . Because it's a start-up , Fewer people , Everyone is in an office , There seems to be no difference between leaders and employees . And I, as the company's first 00 after , It is also the best dish in the company Rookie, My colleagues in the office are all my teachers . The company is doing open source projects , Everyone sends their own code to GitHub On ,Pull Request Then merge . This is very different from the previous project experience in school , In school, everyone is responsible for one piece of content , Finally, the code comes together . In fact, such a workflow will have many problems , Everyone makes cars behind closed doors , If you don't know the progress of other students in the same group , Finally, there will inevitably be problems when merging the code . Open source companies put all their code in GitHub On , Updating the code at any time largely avoids the problem of code conflict , This mode is also for me during my graduate school , It provides a lot of experience when managing the team .

Growing up in learning

When I first joined the company, I was very nervous , The project uses Go Written , Before that, I haven't been in contact with Go Relevant knowledge . Fortunately, the company gave me enough time to adapt , I gradually became familiar with the language , Here I also want to thank B On the site Habour teacher 《 Database system handout 》 This course , He helped me lay a lot of foundation for database research and development . My first week of work in the company made me in a hurry , Learn to use Docker、Go Language and SQL Related knowledge , Teach me how to configure the development environment 、 Solve language problems and so on , No fat beam 、 Lao Gao's patient guidance , I don't think I can get started and become a database developer .

My main work in the company is the development of basic functions, benchmarking and related content . When it comes to development , I have to boast Go The language . Doing projects in school mainly uses C++ and Python,Go In grammar, there are many and C++ Similar places , It has object-oriented characteristics , At the same time, the method of defining functions is more general . most important of all , For someone who has a mild obsessive-compulsive disorder about code format ,Gofmt The mandatory code format of makes me ecstatic . meanwhile Go And have more than Python Dozens of times faster , No wonder many Internet companies in the market are going Go Direction development .

Become the community of Contibutor

The company's project is completely open source , Engineers have a strong atmosphere , Respect all cultures that speak in code ——“Talk is Cheap.Show Me the Code”, The company's product is an open source high-performance time series database , Previously, several foreign companies such as InfluxDB、TimeScaleDB Control the field , This in itself is a very commendable thing . And I have the honor to be one of them , I contributed my own code in the whole product , See your name appear in GitHub On the list of contributors , It has left its own mark in the open source world , I think this is my biggest gain . Vaguely remember my first time in GitHub After submitting the code , Refresh the page repeatedly , Staring at the project Contributor Look at the list , Until your name appears on it , I still remember that sense of achievement . In fact, here , Whether it's Translation 、 Document writing 、 Non code contributions such as design , Or testing 、 Write code and other code contributions , Will be regarded as valuable participation . ad locum , You will also gain a harmony 、 Enthusiastic open source community , Understand the cutting-edge technology . No one will care whether you are a senior developer or a student , What really matters is the quality of your contribution . So what are you waiting for ？ Come and participate in open source , Inherit the spirit of open source .

The process of my work is not always smooth , I remember that I was going to develop related functions about the underlying storage files , Start with deploying the product environment . In order to find the corresponding file , Import data continuously for many times , From a few G To dozens G, Finally found the documents that meet the requirements . The progress of all this , Can't do without the guidance of colleagues .

The most fulfilling time

At work, my colleagues are like my teachers and brothers , In life, they are more like my brothers . Working time in the company is always happy and fulfilling , Go for a walk around Tuanjie Lake Park with my colleagues every noon , Go to the billiard room downstairs and play billiards , Eat ice cream by the flower bed downstairs . When you are tired of work, go downstairs to buy yogurt for convenience bees , Go to Ruixing to buy coffee , I always miss those days when I went to work . I can learn a lot of new knowledge every day , Can leave footprints in the world of open source , Have fun again . What I learned in school is more theoretical knowledge , Textbooks teach us various concepts , But did not say how to achieve . Working is more about turning theory into practice , The process of applying what you have learned . Read the book , travelling , Until work , I just remembered the concepts in the textbook that I can't remember , What's the role . Now I'm very glad that I passed the company's interview at that time , I have the opportunity to apply what I have learned , Have the opportunity to learn more new knowledge . For an undergraduate, one day counts as one day in the first three years “ Day people ” Come on , My senior year at work is my most fulfilling time .
