Summary
This presentation discusses Hypertable, an open source, high performance, distributed database modeled after Google's Bigtable. Doug discusses the differences between Hypertable and traditional database technology, support for massive sparse tables, scaling to petabytes size, and how Hypertable is designed to run on top of an existing distributed file system, such as the Hadoop DFS.
Bio
At Inktomi's Web Search division Doug designed and developed large-scale distributed systems. Later, at Kosmix, Inc., he built a distributed web crawler and scaled it to a billion documents. He also worked at Verity, helping to develop VDK. He is currently Principal Search Architect at Zvents, Inc., and holds four patents in search technology.

They are aware that GPL forces the users of the package to also GPL their product, and so ... you need to provide a dual license model if you want to get any users that wouldn't want to publish their code ? And I'm pretty sure that this is the case with a very big percent of the users.

IANAL, but AFAIK the GPL doesn't force you to give your source code to your client, unless you deliver binaries to them. Ie. if you only create a website, or your service is exposed trough HTTP (HTTPS hopefully), you don't need to give your clients the source code. This is true for both GPLv2 and GPLv3.
There is a variation of the GPL called the AGPL (AGPLv2 and AGPLv3 more precisely), which does make it obligatory to deliver source code, even if you only expose your software trough a network service, but it is not as widely used as GPL. -
There is another similar project called Apache Cassandra. Its still in the incubator. It offers the same BigTable like data model and uses the same Eventually Consistent model from Amazon's Dynamo. It is Apache licensed, which makes life much simpler for most people consuming it.
