Distributed Systems
Distributed Key-Value Store
A fault-tolerant distributed key-value store with replication and consistency guarantees.
C++Distributed SystemsConsistent HashingReplication
A scalable distributed database system that stores key-value pairs across multiple nodes with automatic replication and failure recovery.
Features
- Consistent hashing for data distribution
- Multi-master replication
- Conflict resolution strategies
- Gossip protocol for cluster membership
- Tunable consistency levels (eventual, strong)
Design Decisions
The system uses a ring topology for data distribution and implements vector clocks for tracking causality. Replication is performed asynchronously to maintain high availability while providing configurable consistency guarantees.
Performance
- Sub-millisecond read latency
- Horizontal scalability to hundreds of nodes
- Automatic rebalancing on node additions/removals
- Efficient compression and serialization
