> *Problem*
>  # Local dictionary encoded page is using unsafevarlenghtcolumn column page which internally maintains offset of each value in another column page because of this memory footprint is high.
>  # for complex primitive string data type column page while compressing, it is converting to LV even if it is encoded with dictionary values, because of this store size is high.
> *Solution:*
>  # Use UnsafeFixedLength Column page for local dictionary encoded columns
>  # No need to convert to LV during query if local dictionary is present so use UnsafeFixLength Column page
