Paper Notes - Dynamo: Amazon's Highly Available Key-value Store

Notes and highlights from the paper, added as I read.

Dynamo uses a synthesis of well known techniques to achieve scalability and availability: Data is partitioned and replicated using consistent hashing, and consistency is facilitated by object versioning.

Key ideas

  • Consistent hashing for partitioning and replication
  • Vector clocks for conflict resolution
  • Sloppy quorum and hinted handoff for availability during network partitions
