The only place I see for heartbeat is in controlling a load balancer for
your API nodes. For that, ldirectord and ipvs/lvs should be quite
For the db nodes and mgm nodes, simple monitoring that they are up
should be sufficient. If you want more redundancy for your data you'd be
better off just having 3 replicas and running more db nodes.
Developers: It would be kind of cool if queries got split up evenly
between replica nodes somehow, maybe through some sort of range
selection. It would be even cooler if this was already implemented and I
just didn't know about it... ;)
