Direct discovery is a new functionality where the application data for a selective table can be updated without a full reload of the document.....so every time a new session is created, the data for this direct discovery table is updated selectively while the other Qlikview tables contain the old data....still need more details ?
Through Direct Discovery Functionality u can get real time data. Dimension r loaded into Qlikview Server Memory & Measure come from Database on the fly or selection.
For better understanding read direct discovery technical DOC.
