Hi All! I'd like to start a quick discussion about the way we allow users to trigger savepoints manually in the operator [FLINK-26181] <https://issues.apache.org/jira/browse/FLINK-26181>. There are existing solutions already for this functionality in other operators, for example: - counter based <https://github.com/spotify/flink-on-k8s-operator/blob/master/docs/savepoints_guide.md#2-taking-savepoints-by-updating-the-flinkcluster-custom-resource> - annotation based <https://github.com/spotify/flink-on-k8s-operator/blob/master/docs/savepoints_guide.md#3-taking-savepoints-by-attaching-annotation-to-the-flinkcluster-custom-resource>
We could implement any of these or both or come up with our own approach. It seems, the java-operator-sdk handles the changes of the .metadata and .spec fields of custom resources differently. For further info see the chapter Generation Awareness and Event Filtering in the docs <https://javaoperatorsdk.io/docs/features>. Let me know what you think. Cheers, Matyas
