Does QlikView Server clear the old data form cache after the app reload? Enviornment:
QlikView; all versions
There are still valid cached data after the reload so we don't want to clear it out. This is per design to make the user experience as fast as possible.
The cache is cleared if the server reaches the working set limit, starting with the data that was used the longest ago.
Qlik is designed to be as fast as possible for the user and relies heavily on the cached results.
If the document has a lot of data selections that are only relevant for one user then the cache can of course grow to be very large, if the users make a lot of the same selections it does stay fairly small.
If the cache grows to be to large there is a way to clear it completely without restarting the server.
This should only be done as a last resort and only if you know that you get a lot of cashed values that are not being reused since it can affect performanceHow to clear the cache used by QlikView Server and QlikSense Engine
