When anything is accessed by user[s] then its data is loaded into memory and any selection results cached.
But Qlik has a setting for max % RAM Qlik can use and when this is reached things are released from RAM on a last used algorithm. [Can't remember what the default value is for this, but it is sensible and stated in the online manual somewhere].
Thanks for your answer.
As soon as an app is opened, it is loaded in memory. I would like to know how long it remains in memory. Especially for "my works" apps.
My works apps should remain in memory only during the time user access it.
"Real" streams apps may remain in memory all the time.
What I aim to know is if I have to avoid having a lot of apps in my work stream (for all users) in order to preserve server performance.
