[jira] [Created] (FLINK-32508) Flink-Metrics Prometheus - Native Histograms / Native Counters

Ryan van Huuksloot created FLINK-32508:
------------------------------------------

             Summary: Flink-Metrics Prometheus - Native Histograms / Native Counters
                 Key: FLINK-32508
                 URL: https://issues.apache.org/jira/browse/FLINK-32508
             Project: Flink
          Issue Type: Technical Debt
          Components: Runtime / Metrics
            Reporter: Ryan van Huuksloot
             Fix For: 1.18.0, 1.19.0


There are new metric types in Prometheus that would allow for the exporter to write Counters and Histograms as Native metrics in prometheus (vs writing as Gauges). This requires an update to the Prometheus Client which has changed it's spec.

To accommodate the new metric types while retaining the old option for prometheus metrics, the recommendation is to *Add a new package such as `flink-metrics-prometheus-native` and eventually deprecate the original.*
