Hi Mason, I think this request is reasonable and you could create a JIRA ticket so that we could resolve it later.

If my understanding is right, are you hoping that all state latency metrics for a particular state could be aggregated per state level?

To make metrics aggregation easier, could there be a config to expose something like `state.backend.rocksdb.metrics.column-family-as-variable` that rocksdb provides to do aggregation across column families. In this case, it would be the various components of state. https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/deployment/config/#state-backend-rocksdb-metrics-column-family-as-variable
