I'll try thinking through this some more. One challenge with creating an 
internal vs. user facing id is that a common debugging practice is to take user 
facing id and use it to grep through the logs. A lot of the log statements 
contain the query id they are associated with. So the user would have to 
manually figure out the mapping from the user facing id (perhaps it got the id 
from the runtime profile or the client logs) and the internal id.
