-----------------------------------
Summary: Redundant to querying deployment when creating task
manager pod
Key: FLINK-25648
URL: https://issues.apache.org/jira/browse/FLINK-25648
Project: Flink
Issue Type: Improvement
Components: Deployment / Kubernetes
Affects Versions: 1.14.2
Reporter: Yuan Huang
Attachments: trace.png
When creating Task Manager (TM) Pod, the fabric client needs the deployment to
set owner reference for the TM pod. However, repeating to querying the
deployment each time is unnecessary which will waste a lot of time.
According to the measured result by
https://arthas.aliyun.com/doc/trace.html#id1) below: Quering deployment may
cost more than 50% (203/349 ms) of time.
Can we save the deployment reference in memory instead of querying it each time
to save pod creating time?
