David Anderson commented on FLINK-22528:
----------------------------------------
The documentation should explain:
* Which state backends support this feature.
* The naming scheme for the metrics that are created when this feature is
enabled.
* The scope those metrics can be found in. (Do I end up with operator metrics
on all stateful operators?)
* The expected performance impact of enabling this feature. And a bit of
insight about how they work so I can judge for myself if I want to enable them
in production.
