When Are We Likely To Receive Incorrect (aggregate) Results? |
|
Answer» Very rarely a driver may return aggregated results that are STILL getting processed BACK to client. In this case, client may assume that calculation is complete, INSTEAD of updating with latest or final results. Obviously, driver has to wait for Netezza to complete operation on host COMPUTER, before delivering results.
