zentol opened a new pull request #8002: [FLINK-11923][metrics] MetricRegistryConfiguration provides MetricReporters Suppliers
URL: https://github.com/apache/flink/pull/8002
 
 
   ## What is the purpose of the change
   
   Refactors the `MetricRegistryConfiguration` to provide a `Supplier` for each `MetricReporter` instead of a configuration.
   
   This will make it easier to support reporter factories and makes testing reporters in conjunction with a MetricRegistry significantly easier since you don't have to encode reporters into a Configuration beforehand.
   
   ## Brief change log
   
   * Add `ReporterSetup` for encapsulating reporter-specific arguments for the `MetricRegistryImpl`
   * Move reporter-loading code from `MetricRegistryImpl` to `MetricRegistryConfiguration`
   * Update `MetricRegistryConfiguration`
   
   *(for example:)*
     - *The TaskInfo is stored in the blob store on job creation time as a persistent artifact*
     - *Deployments RPC transmits only the blob storage reference*
     - *TaskManagers retrieve the TaskInfo from the blob cache*
