--------------------------------------
Summary: status.taskManager.replicas to show actual TaskManager
count
Key: FLINK-37448
URL: https://issues.apache.org/jira/browse/FLINK-37448
Project: Flink
Issue Type: Improvement
Components: Kubernetes Operator
Reporter: Robert Metzger
According to the code and documentation, {{status.taskManager.replicas}} shows
a calculated number of TaskManager replicas.
I've opened this ticket to discuss if it makes sense to show the actual
TaskManager count instead.
We have that information already in the codebase:
https://github.com/apache/flink-kubernetes-operator/blob/main/flink-kubernetes-operator/src/main/java/org/apache/flink/kubernetes/operator/service/AbstractFlinkService.java#L753
It shouldn't be too hard to expose that number as taskManager replicas in the
status.
Would this qualify as a breaking change (because we are changing the semantics)?
The information in status.taskManager.replicas is not accurate when using
standalone deployments with reactive mode -- in that case, the actual number of
TaskManagers can change over time and is not determined by the config.
