> TPC-DS Q82 with reducer vectorized join optimizations

> from item, inventory, date_dim, store_sales
> where i_current_price between 30 and 30+30
> and inv_item_sk = i_item_sk
> and d_date_sk=inv_date_sk
> and d_date between '2002-05-30' and '2002-07-30'
> and i_manufact_id in (437,129,727,663)

> and ss_item_sk = i_item_sk
> group by i_item_id,i_item_desc,i_current_price
> order by i_item_id
> limit 100
> {code}
> possibly a trivial plan setup issue, since the NPE is pretty much immediate.
