2. TaskManagerDetailsHandler::createTaskManagerMetricsInfo(MetricsStore.TaskManagerMetricStore)  can  can be used to initialize the fields.
   

Follow-Ups

  • /configuration containing the static values like configuration and hardware description
  • /metrics containing the volatile values like the metrics and slot information

Test Plan

Existing tests are updated to verify feature.
