Fan Zhihui, alicloud database technology expert

Q1: can you introduce yourself briefly? How do you interact with the PostgreSQL community?
Fan ZhihuiHello, my name is fan Zhihui. I started to contact Oracle database in 2007. Before 2010, I had read most of the Oracle documents and did a lot of tests. But the real contact with PostgreSQL is in 2019. Compared with Oracle, the two biggest differences of PostgreSQL are that PostgreSQL is open source and has a very friendly community. It’s also a challenging thing to participate in community discussion. It’s a series of tests about communication skills, mentality, etc. Finally, even if you have done everything you can (including good code, documents, patch splitting, communication language, etc.), there are many times when you have to wait for a long time, because the resources of the community are too short.

Q2: when did you first contact PostgreSQL? How to embark on the road of product development?
Fan Zhihui: I had more than 10 years of Oracle experience before I came into contact with postgressql. Joining the PostgreSQL R & D team is a process of passive selection. In the first month, I just met the battle of a large Internet of things enterprise. In this battle, I found some room for improvement in the optimizer level of PostgreSQL. This is also quite consistent with my past experience, and then I firmly followed this path.

Q3: have you participated in the iteration of PG version function? What are the main contributions?
Fan Zhihui: I will participate in the iteration of the open source community. At present, our own patch has the identification and application of unique key. The patch is in the review state, and is still under development, including the append node’s perception of runtime partition prune. In addition to submitting patches, there are also reviews of other people’s patches and a lot of discussion.

Q4: how do you usually solve the difficulties in product planning or product development? What do you feel most proud (interesting)?
Fan ZhihuiI usually encourage myself. For example, I will talk to myself, “Hi Andy, can you make a clear understanding about X in 8 hours? Ofcourse, let’s see!”. The key point of this dialogue is a clear description of the problem. There will be a lot of further description of the problem. With a time limit, the mental state will be very good. Of course, such a good state is also available every day.
