Rahul Challapalli commented on DRILL-1037:
------------------------------------------

TPCH Query 14 :

select
  100.00 * sum(case
    when p.p_type like 'PROMO%'
      then l.l_extendedprice * (1 - l.l_discount)
    else 0
  end) / sum(l.l_extendedprice * (1 - l.l_discount)) as promo_revenue
from
  lineitem l,
  part p
where
  l.l_partkey = p.p_partkey
  and l.l_shipdate >= date '1994-08-01'
  and l.l_shipdate < date '1994-08-01' + interval '1' month

> The number of rows returned matches the expected value. However the actual data in the
row does not match. Let me know if you need more information regarding data/baselines used.
For scale factor 1GB, the difference seems to be ~0.1, however for scale factor 10GB the difference
is more in the acceptable range (~0.0002). Below is the result from running the query against
1GB data.
