Qlik Sense App and mashup: how the engine works

[venkat_thota]

Hi,

I wanted to know how the Qlik Sesne App and Mashup work on server.

I need to know the process/work flow like I have a app with mashups.

https://servername/extensions/appmashup.html

this mashup has dropdowns, KPIs, charts, all are calculated using lists and hypercubes.

what happens if I open this page? what request sent to QS server? 

what Qlik Engine do in this case? 

will Qlik Engine first loads the app on to memory (RAM) then creates calcuations using Hypercube?

hypercubes use calculation memory or is it separate memory?

I've written a series of blog posts on the basics of the engine API. That might at least contain answers to some of your questions regarding the engine API calls.

Hi Yko...

appreciate your response. 

I wanted to understand more on performance aspects of Hypercube. 

I created a QS app with Mashups. Its taking long time to open and is sporadic. so checking on whether the hypercubes causing any performance issue.
