Day 24: Consistent Hashing for Balanced Log Distribution
What We’re Building Today
Today we implement a production-grade consistent hashing system that solves one of distributed storage’s hardest problems: how to distribute data evenly across nodes while minimizing data movement when nodes join or leave the cluster.
Concrete Deliverables:
Storage Coordinator Service with consistent hashing ring supporting virtual nodes (150+ virtual nodes per physical node)
Three Storage Nodes that automatically register with the hash ring and handle log routing based on hash key
Dynamic Node Management supporting graceful node additions and removals with minimal data rebalancing (affecting only 1/N of data)
Distribution Monitoring showing real-time balance metrics across nodes with load distribution dashboards
