Incremental Reloads from QVDs are slow after upgradeArticle Number: 000053581 | Last Modified: 2018/09/07
Changes occurred from Qlikview 11.20 > 12.00 and Qlik Sense 3.1 > 3.2
Once the table has been loaded from the QVD it will be in memory. At this point aggregations can be performed efficiently, resident load the field, and store the Max/Min value. The Max/Min value can be used as a variable when pulling the newer data from the original data source.
Alternatively, by using the 'Order by' functionality, it is possible to sort the data that will be stored in a QVD based on a field in the dataset so that when it comes time to add newer data the Max value will be first and the Min value will be last.
A Script is attached that was provided by an Implementation Consultant to handle this use case.
