Architecture Overview #

System Architecture #

IceFireDB-Redis-Proxy is designed as a decentralized proxy layer that enhances traditional Redis deployments with P2P networking capabilities. The architecture consists of several key components:

Core Components #

1. Redis Protocol Handler

   • Listens on configured port (default: 16379)
   • Parses Redis protocol (RESP) requests
   • Handles authentication and connection management
   • Routes commands to appropriate backend Redis servers

2. Backend Redis Connector

   • Manages connections to backend Redis servers (standalone or cluster)
   • Handles connection pooling and failover
   • Supports both single-node and cluster Redis deployments
   • Implements read-write separation and load balancing

3. P2P Networking Layer

   • libp2p-based decentralized networking
   • Peer discovery and automatic node connection
   • Data synchronization and change propagation
   • Topic-based messaging for efficient communication

4. Synchronization Engine

   • Change detection from backend Redis operations
   • Conflict detection and resolution strategies
   • Eventual consistency maintenance
   • Command replication across the network

5. Traffic Management

   • Multi-tenant data isolation
   • Read-write separation configuration
   • Command filtering and access control
   • Rate limiting and resource management

Data Flow #

1. Client Request: Redis client connects and sends commands via RESP protocol
2. Protocol Processing: Redis protocol handler parses and validates requests
3. Backend Execution: Commands routed to appropriate backend Redis server
4. Change Detection: Synchronization engine detects data modifications
5. Network Propagation: Changes propagated to other proxy nodes via P2P network
6. Consistency Maintenance: All proxy nodes eventually reach consistent state with their backends

Networking Model #

IceFireDB-Redis-Proxy uses a decentralized P2P networking model with:

• Service Discovery: Automatic peer discovery using DHT (Distributed Hash Table)
• Topic-based Messaging: PubSub system for efficient data propagation
• NAT Traversal: Support for nodes behind firewalls and NAT devices
• Connection Management: Automatic reconnection and fault tolerance
• Mesh Networking: Full mesh connectivity for reliable message delivery

Consistency Model #

The system implements eventual consistency with:

• Operation-based Replication: Redis commands are replicated across nodes
• Conflict Resolution: Timestamp-based resolution for conflicting operations
• Causal Ordering: Preservation of operation causality where possible
• Background Synchronization: Continuous state synchronization between proxies

Performance Characteristics #

• Low Latency: Direct connections to backend Redis servers
• High Throughput: Efficient command routing and parallel processing
• Scalability: Horizontal scaling through additional proxy nodes
• Resource Efficiency: Lightweight proxy layer with connection pooling
• Failover Support: Automatic failover to healthy backend instances

Deployment Modes #

Standalone Mode #

• Single backend Redis server
• Simple deployment for development and testing
• Full P2P synchronization capabilities

Cluster Mode #

• Redis cluster backend support
• Automatic sharding and data distribution
• Cluster-aware command routing
• Failover and replica promotion support

Security Features #

• Transport Encryption: TLS support for client and backend connections
• Authentication: Redis authentication with configurable credentials
• Access Control: Multi-tenant isolation and command filtering
• Network Security: Secure peer authentication and encrypted P2P communications
• Audit Logging: Command logging and access monitoring

Monitoring and Management #

• Health Checks: Regular backend Redis health monitoring
• Metrics Collection: Performance metrics and statistics
• Logging: Comprehensive logging for debugging and audit purposes
• Configuration Management: Dynamic configuration updates
