Infrastructure Primitives
Design a Distributed Key-Value Store
A horizontally-scalable store in the spirit of DynamoDB or Cassandra, trading strict consistency for availability and partition tolerance via consistent hashing and quorum reads/writes.
Open and Simulate this Architecture in InfraDraftCore Architectural Components
Consistent Hashing Ring
Maps keys to nodes and minimizes reshuffling when nodes join or leave.
Replication Manager
Places N replicas of each key across the ring for durability and availability.
Quorum Read/Write Coordinator
Tunes consistency (R + W > N) per operation.
Vector Clocks / Version Vectors
Detects and surfaces concurrent conflicting writes for reconciliation.
Gossip Protocol
Propagates cluster membership and failure-detection state without a central coordinator.
Merkle Trees
Enables efficient anti-entropy repair by diffing replica state without a full data scan.
Write-Ahead Log
Guarantees per-node durability before an in-memory write is acknowledged.
Compaction & SSTable Storage Engine
LSM-tree-style on-disk storage that keeps write throughput high.
