Extracting data from oracle view in QlikSense (Qlik Ver - Nov 2018 patch 6 release) which is taking too much time to load . I am using OLEDB as a data connection and for 18 million data taking 3-4 hours.
In the oracle query I have group by and grouping set both keyword used, that might be one of the reason.
How to overcome this situation? Can anybody suggest any ideas?
