Keynote III: Mind Your State for Your St...

Abstract:  Applications have had an interesting evolution as we've 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 the storage and applications do a subtle dance as they change in support of changing business requirements and environmental challenges. Adding scale to the mix has really stirred things up. This talk and paper look at some of these issues and their impact on our systems.  Bio:  Pat Helland has been building databases, distributed systems, messaging systems, transactional systems, application platforms, big data systems, and multiprocessors since 1978.
