> 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. RequestVote and AppendEntries RPC calls are enriched with sender’s HLC. The HLC update rules are applied on receiving messages. RAFT lease intervals are bound to the HLC range.
