Guide: this article will talk about how to design the database architecture of a high merge system that supports millions of daily active users.

See this topic, many people's first reaction is: sub-library sub-table ah! But in fact, I think many students may not be clear about what the sub-database and sub-table at the database level are used for and how to deal with different scenarios.

Use the development of a startup company as the background to introduce--

If we are now a small startup, the registered users will be 200000, the daily active users will be 10,000, the amount of data per table per day will be 1000, and then the peak concurrent requests per second will be at most 10.

Oh, my God! With regard to this kind of system, you can easily find a senior engineer with several years of work experience, and then bring a few young engineers to do whatever you want.

Because such a system, in fact, is mainly in the early stage of rapid business function development, to make a single system deployed on a server, and then connect to a database on it.

Then everyone keeps filling in all kinds of business codes in a project to support the company's business as soon as possible.
