I'm running some experiments with a 1B row fact table (10 columns). - How can I tell if a column is sorted? - If I generate files in sorted order and use binary bulk loading, will monetdb consider the column sorted? If not, can I force it? I've been reading code, but understanding all the assignments to bn->tsorted is going to take a while. I get the general theme of setting tsorted during bat operations, but I've been unsuccessful in finding where it is initialized when a column is first accessed. TIA, -david
