摘 要：Benchmarks facilitate performance comparison between equivalent systems. They inform procurement decisions, con guration tuning, features planning, deployment valida- tion, and many other e orts in engineering, marketing, and customer support. Benchmarks are important when the un- derlying system enjoys sucient maturity such that the pri- ority moves beyond chaotic feature addition and debugging, and sucient customers and vendors exist such that perfor-mance matters. Big data systems are entering this phase.
