Mostafa Mokhtar created HIVE-8263:
-------------------------------------
Summary: CBO : TPC-DS Q64 is item is joined last with store_sales
while it should be first as it is the most selective
Key: HIVE-8263
URL: https://issues.apache.org/jira/browse/HIVE-8263
Project: Hive
Issue Type: Bug
Components: CBO
Affects Versions: 0.14.0, 0.13.1
Reporter: Mostafa Mokhtar
Assignee: Gunther Hagleitner
Fix For: 0.14.0
Plan for TPC-DS Q64 wasn't optimal upon looking at the logical plan I realized
that predicate pushdown is not applied on date_dim d1.
Interestingly before optiq we have the predicate pushed :

I simplified the query a little bit while still maintaining the query structure
The query :
Note that the final join between cs1 and cs2 has a predicates "cs1.syear =
2000 and cs2.syear = 2000 + 1"
{code}
select cs1.syear ,cs1.cnt
,cs1.s1 ,cs2.syear ,cs2.cnt
from
(select d1.d_year as syear ,count(*) as cnt,sum(ss_wholesale_cost) as s1
,i_item_sk as item_sk
FROM store_sales
JOIN date_dim d1 ON store_sales.ss_sold_date_sk = d1.d_date_sk
JOIN item ON store_sales.ss_item_sk = item.i_item_sk
JOIN
(select cs_item_sk
from catalog_sales JOIN catalog_returns
ON catalog_sales.cs_item_sk = catalog_returns.cr_item_sk
and catalog_sales.cs_order_number = catalog_returns.cr_order_number
group by cs_item_sk) cs_ui
ON store_sales.ss_item_sk = cs_ui.cs_item_sk
WHERE
i_color in ('maroon','burnished','dim','steel','navajo','chocolate')
and
i_current_price between 35 and 35 + 10 and
i_current_price between 35 + 1 and 35 + 15
group by d1.d_year,i_item_sk
) cs1
JOIN
