> Key: CARBONDATA-2735
> URL: https://issues.apache.org/jira/browse/CARBONDATA-2735
> Project: CarbonData
> Issue Type: Bug
> Reporter: kumar vishal
> Assignee: kumar vishal
> Priority: Major
>
> *Problem*
> Query is taking more time when number of elements in array type is more.
> *Root Cause*
> This is because offset of array values are stored in list and when number of elements are high creating a bigĀ list to store offset is taking more timeĀ
> *Solution:*
> Instead of list use column page to store offset so when number of elements are high there will not be any gc.
