Description

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 big list to store offset is taking more time 

Solution:

Instead of list use column page to store offset so when number of elements are high there will not be any gc.
