---------------------------------------
Summary: Share historical stats between coordinators
Key: IMPALA-14598
URL: https://issues.apache.org/jira/browse/IMPALA-14598
Project: IMPALA
Issue Type: New Feature
Reporter: Quanlong Huang
Assignee: Quanlong Huang
Historical stats storing in memory can only be used by the current coordinator
itself. Restarting the coordinator also loss the historical stats. We can store
historical stats in a shared cache, e.g. Redis, to improve this.
