Discuzx2.5 multi-database instance call method

In fact, it is easy for me to create an api or call a database directly. The api can also be used as a cache. Unfortunately, I know little about another project. There is no method for discuz multi-database calling on the internet. today, I'm not sure this is the most suitable for disucz.

What should I do? This is... Embarrassed ....

Some user data information is sourced from another instance in the same database and needs to be changed to cross-database.
