-----------------------------------
Summary: Add query option to force plan hints for insert queries
Key: IMPALA-8673
URL: https://issues.apache.org/jira/browse/IMPALA-8673
Project: IMPALA
Issue Type: Improvement
Components: Backend, Frontend
Affects Versions: Impala 3.3.0
Reporter: Lars Volker
In Impala 3.0 we turned on insert clustering by default (IMPALA-5293). This can
lead to performance regressions from 2.x for highly skewed data sets. To help
with those cases, we should add a way to force plan hints for insert queries
through a query option.
