* The Case for a Session State Storage Layer

This paper motivates the need for a session state storage layer. Session state is used in a large class of applications. Existing session state storage solutions often rely on ad-hoc choices such as databases or file systems, and exhibit various drawbacks such as poor failure/recovery behavior or poor performance, often because the solutions are too general. We present a design for a simple, fast, scalable, and fault-tolerant session state store that we believe accurately addresses the needs of session state retrieval, while avoiding the drawbacks of existing solutions.
