Raft/Paxos Consensus Latency Estimator
Model consensus commit latencies across distributed nodes under various replication configurations and network locations.
Inputs
Cluster Parameters
Client & Leader Locations
Node Location Assignments
Results
Consensus Write Latency
67 ms
Formula
Consensus Latency formula
Write Latency = RTT(Client, Leader) + RTT(Leader, Quorum_Follower)Raft consensus write latency consists of client communication and log replication delays to reach a majority quorum.
Step by step
How the calculation works
- 1Select the cluster node count (typically 3, 5, or 7).
- 2Choose the client location and the consensus leader location.
- 3Assign locations to each node in the cluster. Distributed nodes simulate regional network delays.
- 4Compare Raft (Multi-Paxos 1-RTT commit) and Classic Paxos (2-RTT write phase) latency outputs.
