Yury Gerzhedovich updated IGNITE-19791:
---------------------------------------
    Description: 
As of now, there is unconditional row conversion from storage format to sql 
internal row format. This conversion is quite expensive, and affects 
performance.

To address this issue, lets introduce new RowHandler that apart of already 
existing way to create a row will provide one more to simply wrap row in the 
storage format and do the conversion on demand.

Ultimate goal is to avoid any conversion for queries like {{SELECT * FROM 
table}} .
