Distributed Systems
Dynamo: Amazon's Highly Available Key-value Store
Read original paperAdded January 10, 2025
Summary
Amazon's Dynamo paper presents a highly available and scalable distributed key-value store that sacrifices strong consistency for availability. It introduces concepts like consistent hashing, vector clocks, and quorum-based replication to achieve partition tolerance and availability in distributed systems.
💡 Key Takeaway
Understanding the trade-offs between consistency and availability is crucial for distributed systems. Dynamo demonstrates that eventual consistency can be an acceptable trade-off when availability is paramount, especially for systems like shopping carts where temporary inconsistency is tolerable.
