> 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.
> [https://github.com/apache/flink/blob/36ff71f5ff63a140acc634dd1d98b2bb47a76ba5/flink-kubernetes/src/main/java/org/apache/flink/kubernetes/kubeclient/Fabric8FlinkKubeClient.java]
> (line 128-162)
>  
> 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?
