With mysql copy and read and write separation to solve the problem of reading pressure, then write pressure can also be copied to solve?

The answer is no:

Use cache merge to write multiple times into one time, for example: the number of views can be written into redis, and then write mysql once it reaches n.

Create new db clusters on demand

Synchronously split db into new clusters

Migrate database accounts to corresponding new clusters

Modify an app's data connection

delete chain
