Gyula Fora commented on FLINK-27309:
------------------------------------
Config changes should not affect the running deployments until the user makes
an upgrade (thus generating a new config for deployment). This is also
consistent with the current behaviour as I mentioned earlier.
> Allow to load default flink configs in the k8s operator dynamically
> -------------------------------------------------------------------

> Key: FLINK-27309
> URL: https://issues.apache.org/jira/browse/FLINK-27309
> Project: Flink
> Issue Type: Improvement
> Components: Kubernetes Operator
> Reporter: Biao Geng
> Assignee: Gyula Fora
> Priority: Major
>
> Current default configs used by the k8s operator will be saved in the
> /opt/flink/conf dir in the k8s operator pod and will be loaded only once when
> the operator is created.
> Since the flink k8s operator could be a long running service and users may
> want to modify the default configs(e.g the metric reporter sampling interval)
> for newly created deployments, it may better to load the default configs
> dynamically(i.e. parsing the latest /opt/flink/conf/flink-conf.yaml) in the
> {{ReconcilerFactory}} and {{ObserverFactory}}, instead of redeploying the
> operator.
