Pnuts: Yahoo!'S Hosted Information Serving Platform
Given that spider web users are scattered across the globe, it is critical to guide keep information replicas on multiple continents for low-latency access together with high-availability. Supporting full general transactions is typically unnecessary, since spider web applications tend to manipulate solely ane tape at a time. Moreover, supporting full general transactions (with serializability) over a globally-replicated distributed organisation is expensive together with impractical. On the other hand, it is however useful to guide keep a stronger consistency guarantee than the really weak "eventual consistency". It is oftentimes acceptable to read slightly stale information only having replicas role the same social club of updates is of import because out of social club updates may break undesirable (outside the invariant, unsafe) dry soil at around replicas.
