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}}
