Many of these new technologies have been extremely influential---some
This document discusses distributed programming and data consistency. It defines consistency as how systems and observers perceive the state of a system over time. Consistency has a time aspect, where expected and unexpected sequences of states can occur. Distributed systems like caching introduce inconsistencies when data is replicated across servers. The CAP theorem states that a distributed sys
S3 has an âeventual consistencyâ model, which presents certain limitations on how S3 can be used. Today, Amazon released an improvement called âread-after-write-consistencyâ in the EU and US-west regions (itâs there, hidden at the bottom of the blog post). Hereâs an explanation of what this is, and why itâs cool. What is Eventual Consistency? Consistency is a key concept in data storage: it descri
