R2DBC Composite Primary Key

[ko-ing]

Hi, I was wondering if there's any way I can implement composite primary keys on entities when using spring-data-r2dbc. If there's none, is there any plan for addition or is it okay to create PR for it?

I have searched for some issues and changes but only found #574 and I guess the issue has not been completed.

If I remember correctly, using single primary key is a requirement of the JPA specification. If Spring Data tends to follow the JPA specification, this is clearly an unsolvable problem.👀

Thanks for comment!

I checked javax.persistence package which refers to jpa specification, and there is @IdClass that specifies a composite primary key for an entity. So, I thought jpa specification provides support for composite primary key.

Please comment back if I got it wrong.
And also, I wonder if spring-data-relational repository is not right place to raise this issue?

I don't have much of an idea from this, I'm guessing maybe the bigger limitation comes from Spring Data Commons.
