Hi, I am trying to implement a custom range partitioner in the Flink Iceberg sink. Want to publish some counter metrics for certain scenarios. This is like the network metrics exposed in `TaskIOMetricGroup`.
This requires adding a new setup method to the custom `Partitioner` interface. Like to get feedback from the community. More details can be found in the jira issue [1]. Thanks, Steven [1] https://issues.apache.org/jira/browse/FLINK-35384
