----------------------------------------
Summary: Pass all reporter-specific settings via the
FrontMetricGroup
Key: FLINK-14993
URL: https://issues.apache.org/jira/browse/FLINK-14993
Project: Flink
Issue Type: Improvement
Components: Runtime / Metrics
Reporter: Chesnay Schepler
Assignee: Chesnay Schepler
Fix For: 1.10.0
For the assembly of scopes there currently exist 3 parameters that are defined
per reporter; the reporter index, used to cache scopes separately per reporter,
and the delimiter/filter pair that is applied to each scope.
Currently, the FrontMetricGroup only provides the index, which the
AbstractMetricGroup uses to figure out which delimiter should be used.
Instead we can store the delimiter directly in the FrontMetricGroup; this
simplifies the metric group implementation and further decouples the scope
generation from the MetricRegistry.
