"index of the reporter whose delimiter should be used"
> [metrics] Delimiter should be configured per reporter
> -----------------------------------------------------

> Key: FLINK-4564
> URL: https://issues.apache.org/jira/browse/FLINK-4564
> Project: Flink
> Issue Type: Bug
> Components: Metrics
> Affects Versions: 1.1.0
> Reporter: Chesnay Schepler
> Assignee: Anton Mushin
>
> Currently, the delimiter used or the scope string is based on a configuration
> setting shared by all reporters. However, different reporters may have
> different requirements in regards to the delimiter, as such we should allow
> reporters to use a different delimiter.
> We can keep the current setting as a global setting that is used if no
> specific setting was set.
