I will introduce to Rust, including the principles, the traits, and the current state of the Rust community. After that, I am going to talk about how to build a minimal DBMS from scratch - the StellarSQL project. In this talk, the following is covered. What is a DBMS? What is the architecture of the DBMS? What is the progress in developing the project? What are the existed resources in the community that I use for the developing? The speech would manifest that developing a small DBMS is fascinating and Rust is cool and powerful.
