Comments about oreilly Apache Cassandra in Action:
This video is loaded with in-depth information on Cassandra. No doubt about it. The entire video is divided into 4 parts for download. This video is a presentation on Cassandra by Jonathan Ellis himself in OReilly's Strata Conference. Jonathan Ellis is the cofounder of Cassandra. He now runs Riptano.
Though it goes from basic to advanced topics, this is not for beginners. Knowledge on B-Tree and other DB related concepts are pre-requisite.
The video, I feel, is less interactive and has poor audio quality. The gaps between question sessions is too wide.
Bottom Line No, I would not recommend this to a friend
