------------------------------------
Summary: Pull out MetricsReporter lifecycle from Container
Key: SAMZA-1270
URL: https://issues.apache.org/jira/browse/SAMZA-1270
Project: Samza
Issue Type: Improvement
Reporter: Navina Ramesh
Assignee: Navina Ramesh
Currently, the lifecycle of many components, including the {{MetricsReporter}}
is tied to the container lifecycle. Due to this, StreamProcessor/JobCoordinator
will need to manage their own metrics registry and reporters.
In order to unify the stack, the ideal place for metricsReporter lifecycle will
be in the user-facing apis - LocalContainerRunner & LocalApplicationRunner.
Every component will simply register its metrics to the reporter dynamically.
Iiuc, the {{MetricsReporter}} can implement a
{{ReadableMetricsRegistryListener}} interface to register metrics dynamically.
