             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

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?
