Description

Problem: In case of greater than query on dictionary exclude column of for numeric data type
This is because data is sorted based on string because of this if data is 1,10,2,3 , data will be sorted like 1,10,2,3 but if we search greater than 3 then while applying min max will return false as last value is 3
Solution:we need to sort based on actual data type for this we should have chain comparator based on data type while loading the data, currently disabling DictionaryExclude column for numeric data type and will throw exception. Will raise jira issue to for sorting the based on actual data type
