Review comment:
This is intended. MDCPrivilege has dataconnector as MDataConnector, but
dataconnector itself is actually stored as String in backend Table (because it
cannot store dataconnector type).
The reason why MDCPrivilege can retrieve dataconnector as MDataConnector
even though it is stored as String in backendTable is that DC_NAME here
actually serving as a Foreign Key referencing NAME in DATACONNECTORS table(as
specified in schema when init).
