Client-Centric Consistency Models in Distributed Systems

Explanation of Client-Centric Consistency models in Distributed Systems (also known as session guarantees). Covers such topics as Monotonic Reads, Read Your Writes, Monotonic Writes, Write Follows Reads and Consistent Prefix Reads. In the beginning there is a foundation on what are the client-centric consistency models, and their different with data-centric consistency models.
