I recently gave a talk to our Masters Databases class entitled Current Trends in Distributed Database Systems.
The talk (available here) covers some of the more innovative designs in database systems over the last few years, from Vertica and VoltDB, to larger-scale datastores such as Amazon’s Dynamo.
Major aside: I tried and failed to come up with a more entertaining title for the talk. The suggestions I received on twitter were better, but less relevant (one of the suggestions is on my title slide).
So, if you think you can do better and come up with something that is both relevant and witty/entertaining, there’ll be some form of prize in it for you!
