Hi @sjh120 ,

At present, we can find that some unit tests still report errors (checks -> python package / build ).

Here are my suggestions:

• Please solve these error problems first and pass all unit tests;
• Please add unit tests for the newly added code to ensure that the newly added functions run well and maintain unit test coverage.

Have you ever test this function? Not sure whether primary_key is a dict..If so, we may need to chang the name

I notice that warnings.warn is used here, but it's not necessary compared to log.warning.

How do you think here?

I notice that warnings.warn is used here, but it's not necessary compared to log.warning.

Sure, only use log.warning is enough.

I' will change the code, there are still some flaws in this PR.
