Is there any limitation when join big table cross data base?

#1

Select
*
from “SQLServerSource”.dbo.users u
join “MongoSource”.sales.orders o
on o.user_id = u.UserId

When querying data cross database, is there any limitation existent?

The row count of table？
The row size of dataset be returned？
Or something else？

Thanks
