Create a DBT3 (TPCH) database and load 1gb of data
execute the query #8
select
o_year,
sum(case
when nation = 'UNITED STATES' then volume
else 0
end) / sum(volume) as mkt_share
from
(
select
year(o_orderdate) as o_year,
l_extendedprice * (1 - l_discount) as volume,
n2.n_name as nation
from
part,
supplier,
lineitem,
orders,
customer,
nation n1,
nation n2,
region
where
p_partkey = l_partkey
and s_suppkey = l_suppkey
and l_orderkey = o_orderkey
and o_custkey = c_custkey
and c_nationkey = n1.n_nationkey
and n1.n_regionkey = r_regionkey
and r_name = 'AMERICA'
and s_nationkey = n2.n_nationkey
and o_orderdate between date('1995-01-01') and date ('1996-12-31')
and p_type = 'LARGE PLATED COPPER'
) as all_nations
group by
o_year
order by
o_year;
The same query on InnoDB returned:
------------------+
o_year | mkt_share |
------------------+
1995 | 0.04715849 |
1996 | 0.05004456 |
