[jira] [Created] (FLINK-23519) Aggregate State Backend Latency by State Level

Mason Chen created FLINK-23519:
----------------------------------

             Summary: Aggregate State Backend Latency by State Level
                 Key: FLINK-23519
                 URL: https://issues.apache.org/jira/browse/FLINK-23519
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Metrics, Runtime / State Backends
    Affects Versions: 1.13.0
            Reporter: Mason Chen


To make metrics aggregation easier, there should be a config to expose something like `state.backend.rocksdb.metrics.column-family-as-variable` that rocksdb provides to do aggregation across column families ([https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/deployment/config/#state-backend-rocksdb-metrics-column-family-as-variable]).
 
In this case of state backend latency, the variable exposed would be state level instead column family. This makes it easier to aggregate by the various state levels that are reported.
