We can split some SQL, maybe we can try to do it first. At least change what 
can be changed first.

The database belongs to the underlying service, and most of the
bottlenecks are often in the database. It is recommended that the database
is only used as a tool for the data store, and not concerned with the
business. Therefore, I suggest that it is better not to write all kinds of
join SQL, it may be better to leave it to the business layer to do the
association. What do you think?
