Hi Akshay,
The mail description and document content are not matching. For
single-level struct also document says cannot support.
So, please list down all the work that need to be done in points and
then divide which is supported in phase1 and which is supported in phase 2
clearly in the summary section of the document.

Also in the query flow, after adding the column, for previously loaded
segments what will be the output NULL or empty complex type ?
you can refer hive behavior for this.  Hope schema evolution (column drift)
also intact with complex column support.

Thanks,
Ajantha
