Aggregate State Backend Latency by State Level

    XMLWordPrintableJSON

    Details

      Description

      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.
