The Facebook guys who wrote Cassandra have heavily drawn its design and terminology from Google's Bigtable. By the way, Column Family (CF) in BT makes a lot more sense because the compression of data,as well as disk storage locality, is made on a per-CF basis. They have even filled a patent about this (http://bit.ly/ooop2s). Oddly enough, BigTable's terminology seems fits more naturally in the classic concepts than Cassandra's. Maybe it's the result of Dynamo's design choices (DHT, etc) that got into the mix or new concepts like SuperColumn. |
