> Key: FLINK-29847
> URL: https://issues.apache.org/jira/browse/FLINK-29847
> Project: Flink
> Issue Type: Improvement
> Components: Kubernetes Operator
> Reporter: Daren Wong
> Priority: Major
>
> Kubernetes operator currently uploadJar always even when the same JAR has
> been uploaded to JM previously. For example, this occurs during rollback and
> suspend-run 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.
