Hi, Valeria, I see your point about the data actually being different, however, it would be a lot easier for us if we can rely on the fact that the data partitions are named uniquely. If the names are not unique, it would be harder for us to handle the queries with a FROM clause.
Is there any chance you can assign a different name to each data partition? Thanks.
