-------------------------------------
Assignee: (was: Alexander Behm)
> Performance regression introduced by "IMPALA-3828 Join inversion"
> ------------------------------------------------------------------
>
> Key: IMPALA-4040
> URL: https://issues.apache.org/jira/browse/IMPALA-4040
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Affects Versions: Impala 2.7.0
> Reporter: Mostafa Mokhtar
> Priority: Major
> Labels: regression
>
> IMPALA-3828 improved several TPC-DS queries but introduced a regression to
> queries 10 and 17.
> The regression in TPC-DS Q10 is because the runtime filters in the old plan
> had a cascading effect mimicking a bushy execution plan.
> Unfortunately filtering from runtime filters is not accounted for by the
> planner and one of the scan nodes is moved to a location where runtime
> filters no longer have this cascading effect.
> For TPC-DS Q10 before IMPALA-3828 RF001 created from customer_address was
> pushed on to customer creating RF002 which is very selective and eventually
> gets pushed to web_sales, catalog_sales and store_sales.
> Post IMPALA-3828 RF001 gets pushed on the customer table but in the new plan
> the customer scan node is the left most node in the subplan and as a result
> no runtime filters from customer gets pushed onto the *_sales fact tables
> which dominate the cost of the plan.
