Distributed Cache Layer

Built a production-grade distributed caching system in Go featuring consistent hashing for load balancing, multi-replica setup with automatic failover, and AOF persistence. The system handles 2M+ requests per second with sub-millisecond latency. Implemented cluster management via gossip protocol and lock-free data structures for high-performance concurrent access.

The architecture uses consistent hashing to distribute keys across nodes with minimal redistribution during scaling. Each node maintains replicas for durability, and failed nodes are automatically replaced. This design achieves near-linear scalability.
