Hi
Some more info :
In release 1.1.1, there was a good improvement "measure filter
optimization", system will use minmax index to do filter for measure
column filter.
So for INT column to get good filter: one way you can add the INT column to sort_columns, another way, system will automatically use the INT column's minmax index to get good filter.
Regards
