JOIN is ok, foreign key should be avoided, do you have real requirements?

@jcwangxp if foreign key doesnt add much overhead, can support but otherwise can do another version that supports it.

definitely have use case for implementation value.

but i prefer if u can keep this as lightweight as possible. in fact i think u can do an x version that extremely lightweight

3 versions
x <- ultra lightweight
normal <- simple version without foreign key / join
e version with foreign key / join
