Task reload performance Normal app vs app built on top of QVD

[VamsiBhagavathula1]

Hello All,

Does anyone can tell me benefit of creating a qvd file in qliksense and building an app on top it.

Why cant we do the same (meaning running sqls) and load data into a normal app rather than building a qvd and create another app on top the qvd?? Later we anyway have to create 2 more task reloads to get the data updates .

Whats the best approach. Which one is more performance oriented.

Best Regards

Vamsi

You can do either one. There is no requirement to use QVDs (unless your organization decides otherwise, but that's not a technical requirement). Performance will be slightly better if you load directly from the database vs. if you load from the database, store to QVD, and then read from QVD, assuming the data is only used in a single app and there is no incremental reload option.
