Difference between inter-node and spread communications?
Regarding how nodes in a cluster interact with one another, is there a difference between "inter-node and spread communications"? I see this reference in th admin doc a lot.

Spread communications take place at the UDP layer and are used for heartbeat traffic. Internode communications happen using multiplexed TCP for data movement.
