WebBounded staleness is suitable for scenarios that need to control search latency and can accept sporadic data invisibility. For instance, in recommender systems like video recommendation engines, data invisibility sometimes has small impact on the overall recall rate, but can significantly boost the performance of the recommender system.

More precisely, we present algorithms and models for predicting the staleness of partial quorums, called Probabilistically Bounded Staleness (PBS). There are two common metrics for measuring staleness in the literature: WebA bounded staleness read is a historical read that uses a dynamic, system-determined timestamp to minimize staleness while being more tolerant to replication lag than an exact staleness read. Bounded staleness reads also help increase system availability, since they provide the ability to serve reads from local replicas even in the presence of ...
