   @pvary, in Spark the rules are:
   
   1. If the name has one identifier part, then use the current catalog and namespace with identifier as the table name
   2. If the multi-part identifier does not start with a catalog name, use the current catalog with the identifier's namespace and table name
   3. If the multi-part identifier starts with a catalog name, it is a full identifier. Use the catalog, namespace, and table name from the identifier
   
   Those never produce ambiguity. The trade-off is that if you use a table name like `customers.history` (where `customers` is a table) then Spark will not fill in the current database/schema name for the namespace. Spark would be able to find `customers` and resolve it to `current_catalog.current_namespace.customers` though.
