Jungtaek Lim commented on STORM-885: ------------------------------------ [~knusbaum] I just would like to see its progress, as I'm a fan of heartbeat server. In addition I'd like to ask a question: does it support H/A itself? It should be, cause it could be a new SPOF. > Heartbeat Server (Pacemaker) > ---------------------------- > > Key: STORM-885 > URL: https://issues.apache.org/jira/browse/STORM-885 > Project: Apache Storm > Issue Type: Improvement > Components: storm-core > Reporter: Robert Joseph Evans > Assignee: Kyle Nusbaum > > Large highly connected topologies and large clusters write a lot of data into > ZooKeeper. The heartbeats, that make up the majority of this data, do not > need to be persisted to disk. Pacemaker is intended to be a secure > replacement for storing the heartbeats without changing anything within the > heartbeats. In the future as more metrics are added in, we may want to look > into switching it over to look more like Heron, where a metrics server is > running for each node/topology. And can be used to aggregate/per-aggregate > them in a more scalable manor. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
