[jira] [Created] (DRILL-7154) TPCH query 4 and 17 take longer with
sf 1000 when Statistics are disabled
Robert Hou created DRILL-7154:
---------------------------------
Summary: TPCH query 4 and 17 take longer with sf 1000 when Statistics are disabled
Key: DRILL-7154
URL: https://issues.apache.org/jira/browse/DRILL-7154
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Affects Versions: 1.16.0
Reporter: Robert Hou
Assignee: Boaz Ben-Zvi
Fix For: 1.16.0
Attachments: 235a3ed4-e3d1-f3b7-39c5-fc947f56b6d5.sys.drill, 235a471b-aa97-bfb5-207d-3f25b4b5fbbb.sys.drill, hashagg.nostats.log, hashagg.stats.disabled.log
Here is TPCH 04 with sf 1000:
{noformat}
select
o.o_orderpriority,
count(*) as order_count
from
orders o
where
o.o_orderdate >= date '1996-10-01'
and o.o_orderdate < date '1996-10-01' + interval '3' month
and
exists (
select
*
from
lineitem l
where
l.l_orderkey = o.o_orderkey
and l.l_commitdate < l.l_receiptdate
)
group by
o.o_orderpriority
order by
o.o_orderpriority;
{noformat}
TPCH query 4 takes 30% longer. The plan is the same. But the Hash Agg operator in the new plan is taking longer. One possible reason is that the Hash Agg operator in the new plan is not using as many buckets as the old plan did. The memory usage of the Hash Agg operator in the new plan is using less memory compared to the old plan.
Here is the old plan:

I have attached two profiles. 235a471b-aa97-bfb5-207d-3f25b4b5fbbb is from commit id 4627973bde9847a4eb2672c44941136c167326a1. This does not have Statistics code and serves as the baseline. It is the commit prior to the Statistics commit. 235a3ed4-e3d1-f3b7-39c5-fc947f56b6d5 is from commit id 5c436dbb028b813e80b7b8fcf045af31f0bcf68b. This has the Statistics code with the fix for disabled Statistics.
I also pulled the logs from the foreman to show the memory limit for Hash Agg. With the baseline, HashAgg has a limit of 10GB:
