Keynote: Mind Your State for Your State of Mind

Applications have had an interesting evolution as they have moved into the distributed and scalable world. Similarly, storage and its cousin databases have changed side by side with applications. Many times, the semantics, performance, and failure models of storage and applications do a subtle dance as they change in support of changing business requirements and environmental challenges.  

Different types of distributed stores offer various average speeds, variation in responsiveness, capacity, availability, and durability. This talk provides a partial taxonomy of diverse storage solutions available over a distributed cluster. Part of this is an exploration of the interactions among different features of a store. The talk then considers how distinct application patterns have grown over time to leverage these stores and the business requirements they meet. It concludes with a set of actionable takeaways.
