An optional add-on component that you can purchase for faster loads of data to Greenplum, Netezza, and Teradata targets. DataStreamer streams the unloaded Oracle data directly to the Greenplum parallel file distribution server (gpfdist), to the Netezza external tables, or to the Teradata Parallel Data Pump, FastLoad, or MultiLoad utility for loading to the targets. You must use the direct path unload method. Because DataStreamer does not use Fast Clone data files, you do not need to reserve storage for these files.
