zentol opened a new pull request #7095: [FLINK-10867][metrics] Cache logical scopes separately for each reporter URL: https://github.com/apache/flink/pull/7095 ## What is the purpose of the change This PR fixes an issue in the metric system where the logical scope was not cached separately for each reporter. As a result other reporters might access logical scopes for which the wrong filter and/or delimiter was used. ## Brief change log * cache logicalScopeStrings separately each reporter * modify `FrontMetricGroup` to inject reporterIndex when computing logical scope ## Verifying this change This change added tests and can be verified as follows: * run `AbstractMetricGroupTest#testLogicalScopeCachingForMultipleReporters`
