> 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.
