--------------------------------
Summary: Improve recovery performance by querying all pods once
instead of querying pods on specified node for many times
Key: YUNIKORN-85
URL: https://issues.apache.org/jira/browse/YUNIKORN-85
Project: Apache YuniKorn
Issue Type: Improvement
Components: shim - kubernetes
Reporter: Tao Yang
Recently I did some performance tests on kubemark cluster with 1k hollow nodes,
and found the recovery phase will take almost 1 minute, querying pods on
specified node one by one is the most time-consuming logic inside. Therefore I
propose to query all pods once here to improve the recovery performance, after
this improvement, the cost time of recovery phase can reduce to only 2 seconds.
