Benchmarks for scalability in NoSQL systems?
My answer to Benchmarks for scalability in NoSQL systems? on Quora
NoSQL systems are enormously varied which makes it hard (and not particularly constructive) to benchmark them against each other. How would you compare the performance of Redis, an in-memory data structure server, with Cassandra, a distributed redundant column store?
By far the most useful benchmarks are the ones you run yourself against your own test data designed to reflect the specific workload of your own application.
