Wang Jian, senior operation and maintenance engineer of alicloud database
Q1: can you introduce yourself briefly? How do you interact with the PostgreSQL community?
Wang JianHello everyone, my name is Wang Jian, and the flower’s name is Jiang Yun. Before joining Alibaba in 2018, I worked in a domestic database manufacturer. I probably got in touch with PG database since 2015. In the process of learning, there are big bull blogs such as de Ge for reference, and also with the help of colleagues. In the process of constantly understanding PG, they began to participate in some community meetings and activities to get to know more students. The technology has been greatly improved through continuous communication and learning. Participating in community activities is a good opportunity to improve yourself. You can get to know a lot of technical bulls and know the latest trends and technical points of PG.

Q2: how do you solve the difficulties in product planning or product development? What do you feel most proud (interesting)?
Wang Jian: in the process of learning PG, you should start from official documents and blog. If you encounter any problems, you will first consult the official documents or blog, and then you will start to read some foreign technical blogs, such as EDB and the second quadrant, crunchy Data, etc. friends familiar with PG may know that PG has a wealth of plug-ins. After opening GitHub, you will find a new treasure and find a large number of useful PG plug-ins waiting for you to dig. In the last stage, I began to learn the code of PG kernel. I found that there were many problems that could not be found in the search engine. I would check the code and manually debug it to help me solve the problem. At the same time, I could learn the principle of database. The most interesting thing is to solve a problem that has been bothering for a long time, and you will gain great satisfaction.

Q3: how do you think database products will have more vitality in the future?
Wang JianFirst of all, the functional level should be more in line with the use scenarios of enterprise users, and secondly, reduce the difficulty of new users to use the database easily.

Q4: finally, do you have any suggestions for the netizens who want to engage in the research and development of PG products or technologies?
Wang JianTo keep curiosity, we need to have the spirit of breaking through the casserole, practice more and explore more.
