----------------------------------
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.
