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.
