Description

RAFT events help to synchronize HLC between RAFT replicas. All RAFT communications are initiated by a leader, and only one leader can exist at a time. This enforces monotonic growth of HLC on raft group replicas. Heartbeat AppendEntries RPC calls are enriched with sender’s HLC. The HLC update rules are applied on receiving messages.
