-------------------------------------
Summary: Harden and separate MetricQueryService
Key: FLINK-10246
URL: https://issues.apache.org/jira/browse/FLINK-10246
Project: Flink
Issue Type: Improvement
Components: Distributed Coordination, Metrics
Affects Versions: 1.6.0, 1.5.3, 1.7.0
Reporter: Till Rohrmann
Fix For: 1.6.1, 1.7.0, 1.5.4
This is an umbrella issue to track the effort to harden Flink's
{{MetricQueryService}} and to separate it from the rest of the system.
The idea is to setup the {{MetricQueryService}} and the metric system in
general in such a way that it cannot interfere with or even bring the main
Flink components down. Moreover, the metric system also should not degrade
performance by simply using any free CPU cycles but not more. Ideally, the user
does not see a difference between running Flink with metric query service
turned on or off.
