Patrik Nordwall 3f73705abc Use consistent hash to heartbeat to a few nodes instead of all, see #2284 ... * Previously heartbeat messages was sent to all other members, i.e. each member was monitored by all other members in the cluster. * This was the number one know scalability bottleneck, due to the number of interconnections. * Limit sending of heartbeats to a few (5) members. Select and re-balance with consistent hashing algorithm when new members are added or removed. * Send a few EndHeartbeat when ending send of Heartbeat messages.		2012-10-08 08:41:28 +02:00
