Andy Bennett on "Scalable Atomic Visibility with RAMP Transactions"

Bailis et al formalise "Read Atomic" isolation which is a database isolation level sufficient for many applications which make use of large,distributed databases in real world applications. They then show how to design a database system which provides this isolation level whilst allowing read, write and read/write transactions on data across multiple partitions: partitions which do not need to communicate with each other.This method is both performant and fairly portable to existing architectures and allows database authors to implement much stronger guarantees than are currently available from systems in use at companies such as Facebook, LinkedIn, Yahoo or Amazon.

In this talk we will explore the contributions of this paper and how they can be used solve some of the anomolies encountered in today's multi-node, distributed, database systems and accompanying applications.
