Current Trends in Database Systems Talk

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.

2010-12-13 - Current Trends in Distributed Database Systems


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!

SICSA Conference 2010

I’m just back from presenting a paper and poster at the SICSA Conference 2010.

You can find the work that I presented at the conference below, and more information on H2O in general at the project webpage.


H2O: An Autonomic, Resource-Aware Distributed Database System


This paper presents the design of an autonomic, resource-aware distributed database which enables data to be backed up and shared without complex manual administration. The database, H2O, is designed to make use of unused resources on workstation machines.

Creating and maintaining highly-available, replicated database systems can be difficult for untrained users, and costly for IT departments. H2O reduces the need for manual administration by autonomically replicating data and load-balancing across machines in an enterprise.

Provisioning hardware to run a database system can be unnecessarily costly as most organizations already possess large quantities of idle resources in workstation machines. H2O is designed to utilize this unused capacity by using resource availability information to place data and plan queries over workstation machines that are already being used for other tasks.

This paper discusses the requirements for such a system and presents the design and implementation of H2O.
