Zhong Yanghong updated KYLIN-2722: ---------------------------------- Affects Version/s: (was: v2.0.0) v2.2.0 > Introduce a new measure, called active reservoir, for actively pushing > metrics to reporters > ------------------------------------------------------------------------------------------- > > Key: KYLIN-2722 > URL: https://issues.apache.org/jira/browse/KYLIN-2722 > Project: Kylin > Issue Type: Sub-task > Affects Versions: v2.2.0 > Reporter: Zhong Yanghong > Assignee: Zhong Yanghong > Attachments: APACHE-KYLIN-2722.patch > > > For many existing metrics frameworks, they focus on maintaining metrics in > memory independently for each instance. However, kylin server may consist of > multiple instances. Thus we extend existing metrics framework by introducing > *active reservoir* to actively push metrics to reporters which will report > metrics of its instance to a unified storage. > Here we introduced two *active reservoirs*. One is called > {{BlockingReservoir}}, which will buffer the metrics. The other is called > {{InstantReservoir}}, which owns no buffer and will directly push metrics to > reporters. > Generally, one *active reservoir* can push its metrics to multiple reporters > and one reporter can only listen on one *active reservoir*. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
