Before today’s article, let’s recall what I wrote in these days.

First, you should know DBMS is based on servers. A well designed DBMS such as MySQL or PostgreSQL, would implement very underlying layers by themselves for high quality and well performance. As I said before, I will focus on database and SQL, so I just use Tokio.rs for handling server tasks, including task scheduler, thread, I/O, etc. Of course, it would be great if I have time implement these modules in my own way in the future.

Then, I talked about client/server protocol yesterday, and I will implement the remaining part today.
