------------------------------------------
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.*
