----------------------------------
Summary: Store/cache JarUploadResponseBody
Key: FLINK-29847
URL: https://issues.apache.org/jira/browse/FLINK-29847
Project: Flink
Issue Type: Improvement
Components: Kubernetes Operator
Reporter: Daren Wong
Fix For: kubernetes-operator-1.3.0
Kubernetes operator currently uploadJar always even when the same JAR has been
uploaded to JM previously. For example, this occurs during rollback operation.
To improve the performance, we want to cache the JarUploadResponseBody so that
in the next runJar operation, kubernetes operator will check the cache and
reuse the jar if it's the same JAR. This "cache" can be as simple as storing
the uploaded JarFilePath in the CR Status field.
