The data is stored in memory and connected directly to memory.

It is implemented by the relatively low-level C language, which is closer to the operating system.

The realization of the source code is very exquisite, only tens of thousands of lines of code, simple and stable.

The single-threaded model is used, and there is no multi-thread competition, lock and other problems.
