Fault Tolerance Mechanisms
Raft Consensus
All operations reach consensus among a majority of servers through the Raft protocol, ensuring data consistency.
Automatic Failure Recovery
When the leader fails, the system automatically elects a new leader, keeping the service available.
Data Replication
All data is automatically replicated to multiple servers, allowing the system to continue operating even if some servers fail.
Snapshot Mechanism
Regular snapshots are created to reduce log size and speed up recovery.
