Data volume is how many records you have while the size of an app in-memory is a factor of two parts – the data being analyzed and the complexity of the analysis. Qlik Sense also highly compresses data so in-memory app size is often smaller than the raw data size. Typically tens of millions of records fit in the app size limit, even if your app is complex. If you have larger data sets or need more complex analysis, this can be achieved through a variety of app design techniques and, if needed, by increasing your maximum app size limit.
