O’Reilly Webcast – Extending Cassandra for OLAP

oreilly doradusColleague Randy Guck, who leads our open source Doradus project, recent gave an O’Reilly Webcast on the project and using Doradus to extend Cassandra for high performance analytics.

The discussion on how Doradus leverages Cassandra, its data model and query language, the internal architecture and the concept of storage services gave in-depth background to then understand the Doradus OLAP service and how it provides near real-time data warehousing.

Randys’ slides and webcast can be fund here. It does need registration, but is well worth the effort. The webcast was sponsored by Dell, which was entirely coincidental, since it was for a Hadoop services offering. Doradus offers some interesting ways to extend and use Cassandra and Randy covers most of them in the webcast. The key point is, that Doradus is an open source project, use and source code are free. Details on Doradus are in this blog entry.
