-----------------------------------
Summary: Metrics library upgrade
Key: KAFKA-8721
URL: https://issues.apache.org/jira/browse/KAFKA-8721
Project: Kafka
Issue Type: Improvement
Components: metrics
Affects Versions: 2.3.0
Reporter: Mario Molina
The current metrics library which Kafka is using is pretty old (version 2.2.0
from Yammer and now we have 4.1.0 from Dropwizard).
In the latest versions of the Dropwizard library (which comes from Yammer and
this is deprecated), there are a lot of bugfixes and new features included
which could be interesting for the metrics (ie: Reservoris, support JDK9, etc).
This patch includes the upgrade to this new version of the library so that we
could add new features in Kafka metrics.
