Speaker: Catalin Avram Abstract: This talk discusses the hurdles and benefits of moving web applications and their data to the edge of the cloud; proposes a transactional model for the resulting distributed system and motivates further research into building a distributed online algorithm for transaction execution and dynamic data placement.

Speaker: Ken Salem Abstract: I'll give an overview of some recent systems, e.g., Spanner, MDCC, Granola, and Megastore, that implement transactions over replicated partitioned databases, and will try to place them in context.

Speaker: Xin Pan Abstract: Various High Availability DataBase systems (HADB) are used to provide high availability. Pairing an active database system with a standby system is one commonly used HADB techniques. The active system serves read/write workloads. One or more standby systems replicate the active and serve read-only workloads.

Speaker: Ihab Ilyas

Speaker: Dan Farrar, SAP Waterloo Abstract:

I will revisit the seminal 1994 paper [1] by Goetz Graefe that describes the parallel Volcano query evaluation model. I will talk about the power of the Volcano model, its relevance to the hardware landscape today (SSDs, in-memory stores, massively multi-core systems), and the engineering challenges of getting it implemented correctly.
