Benchmarking Top NoSQL Databases [pdf]

Have these been independently verified? Datastax is great but Cassandra is still their main product.

Our perf team and our technical marketing team wrote a post about this specific benchmark. Hopefully Datastax will clarify. (I work at Couchbase but wasn't involved in this work.)

My personal opinion is that using a vendor benchmark to choose your data stack is like hiring a bodyguard based on their record in professional wrestling.
