----------------------------------------
Summary: Support MetricReporter factories
Key: FLINK-11922
URL: https://issues.apache.org/jira/browse/FLINK-11922
Project: Flink
Issue Type: New Feature
Components: Runtime / Metrics
Reporter: Chesnay Schepler
Assignee: Chesnay Schepler
Fix For: 1.9.0
Currently we only support instantiating {{MetricReporters}} via reflection,
forcing us (and implementees) to deal with numerous downsides such as non-final
fields (resources can only be acquired in open()), frustrating test setup
(options must always be encoded in a {{Configuration}}, and requiring non-arg
constructors.
Factories are a more appropriate way of dealing with this, and as such we
should add support for it. Existing reporters can be ported to this mechanism
without affecting users.
