Aman Sinha created DRILL-4794: --------------------------------- Summary: Regression: Wrong result for query with disjunctive partition filters Key: DRILL-4794 URL: https://issues.apache.org/jira/browse/DRILL-4794 Project: Apache Drill Issue Type: Bug Components: Query Planning & Optimization Affects Versions: 1.7.0 Reporter: Aman Sinha Assignee: Aman Sinha
For a query that contains certain types of disjunctive filter conditions such as 'dir0=x OR dir1=y' we get wrong result when metadata caching is used. This is a regression due to DRILL-4530. Note that the filter involves OR of 2 different directory levels. For the normal case of OR condition at the same level the problem does not occur.
