-----------------------------------------------------

             Summary: Avro file format should validate the query with schema before processing.
                 Key: DRILL-3699
                 URL: https://issues.apache.org/jira/browse/DRILL-3699
             Project: Apache Drill
          Issue Type: Improvement
          Components: Storage - Other
            Reporter: Bhallamudi Venkata Siva Kamesh
            Assignee: Jacques Nadeau


For avro data, as schema will be available with data, Drill can evaluate the query with the
schema before processing. This will avoid unnecessary processing and gives users a meaningful
information, if the field, a user is using in the query does not exist in the data file.
