[jira] [Created] (IMPALA-8673) Add query option to force plan hints for insert queries
Lars Volker created IMPALA-8673: --- 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
