[jira] [Created] (IMPALA-15548) Add query option to bound the time reading HBO stats

Quanlong Huang created IMPALA-15548:
---------------------------------------

             Summary: Add query option to bound the time reading HBO stats
                 Key: IMPALA-15548
                 URL: https://issues.apache.org/jira/browse/IMPALA-15548
             Project: IMPALA
          Issue Type: New Feature
            Reporter: Quanlong Huang
            Assignee: Quanlong Huang


While using remote storage (e.g. Redis) as HBO cache backend, the time reading HBO stats could be significant. We need a limit to bound the reading time. When the limit is reached, planner keeps using the static estimation.
