I was ran simple benchmark
* Cluster : 1Master + 4Worker
* TPC-H 100GB part of Q16
```
select
p_brand, p_type, p_size, ps_suppkey
from
partsupp ps join part p
on
p.p_partkey = ps.ps_partkey and p.p_brand <> 'Brand#45'
and not p.p_type like 'MEDIUM POLISHED%'
join supplier_tmp s
on
ps.ps_suppkey = s.s_suppkey;
