[jira] [Created] (HIVE-21633) Estimate range for value generated by aggregate function in statistics annotation

Jesus Camacho Rodriguez created HIVE-21633:
----------------------------------------------

             Summary: Estimate range for value generated by aggregate function in statistics annotation
                 Key: HIVE-21633
                 URL: https://issues.apache.org/jira/browse/HIVE-21633
             Project: Hive
          Issue Type: Bug
          Components: Statistics
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez
         Attachments: HIVE-21633.patch

In some cases, we can infer the estimate of the range for a value generated by an aggregate function during statistics annotation. For instance, we can estimate the min of the sum of a column with positive min value as that same min value.
