"I want to know what's the performance of the SQL solutions cited in the article." Vertica will happily arrange for a demo, and they even have a fast track for getting a cluster up on ec2. Teradata, Greenplum and the others you're dealing with the traditional enterprise sales process (bleh). "all the SQL solutions cited in the article are names I never heard before of today." This is sort of the point. While they may only be represented in the enterprise market rather than in FOSS, there are linearly scalable database products available today. For businesses that have the funding, these can have huge advantages over the options being birthed by NoSQL (as well as drawbacks). And the larger point is that the majority of the OSS world working on NoSQL (or Mysql Cluster for that matter) is somewhat ignorant of the parallel database research of the 80's. I'd suggest starting with the position paper "End of an Architectural Era", and then continuing with DeWitt's publications.
