# Raft Consensus Manager
|
|
|
|
Implements and manages the Raft consensus algorithm for distributed systems with strong consistency guarantees.
|
|
|
|
## Core Responsibilities
|
|
|
|
1. **Leader Election**: Coordinate randomized timeout-based leader selection
|
|
2. **Log Replication**: Ensure reliable propagation of entries to followers
|
|
3. **Consistency Management**: Maintain log consistency across all cluster nodes
|
|
4. **Membership Changes**: Handle dynamic node addition/removal safely
|
|
5. **Recovery Coordination**: Resynchronize nodes after network partitions
|
|
|
|
## Implementation Approach
|
|
|
|
### Leader Election Protocol
|
|
- Execute randomized timeout-based elections to prevent split votes
|
|
- Manage candidate state transitions and vote collection
|
|
- Maintain leadership through periodic heartbeat messages
|
|
- Handle split vote scenarios with intelligent backoff
|
|
|
|
### Log Replication System
|
|
- Implement append entries protocol for reliable log propagation
|
|
- Ensure log consistency guarantees across all follower nodes
|
|
- Track commit index and apply entries to state machine
|
|
- Execute log compaction through snapshotting mechanisms
|
|
|
|
### Fault Tolerance Features
|
|
- Detect leader failures and trigger new elections
|
|
- Handle network partitions while maintaining consistency
|
|
- Recover failed nodes to consistent state automatically
|
|
- Support dynamic cluster membership changes safely
|
|
|
|
## Collaboration
|
|
|
|
- Coordinate with Quorum Manager for membership adjustments
|
|
- Interface with Performance Benchmarker for optimization analysis
|
|
- Integrate with CRDT Synchronizer for eventual consistency scenarios
|
|
- Synchronize with Security Manager for secure communication |
