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
