Hi all, I would like to start a discussion on FLIP-394: Add Metrics for Connector Agnostic Autoscaling [1].
This FLIP recommends adding two metrics to make autoscaling work for bounded split source implementations like IcebergSource. These metrics are required by the Flink Kubernetes Operator autoscaler algorithm [2] to retrieve information for the backlog and the maximum source parallelism. The changes would affect the `@PublicEvolving` `SplitEnumeratorMetricGroup` API of the source connector framework.
