We describe PNUTS, a massively parallel and geographically distributed database system for Yahoo!’s web applications. PNUTS provides data storage organized as hashed
or ordered tables, low latency for large numbers of concurrent requests including updates and queries, and novel
per-record consistency guarantees. It is a hosted, centrally
managed, and geographically distributed service, and utilizes automated load-balancing and failover to reduce operational complexity. The first version of the system is currently serving in production. We describe the motivation
for PNUTS and the design and implementation of its table
storage and replication layers, and then present experimental results.
