BG: A scalable benchmark for interactive social networking actions.

BG is a benchmark that rates a data store for processing interactive social networking actions such as view a member profile and extend a friend invitation to a member. It elevates the amount of stale, inconsistent, and erroneous (termed unpredictable) data produced by a data store to a first class metric, quantifying it as a part of the benchmarking phase. It summarizes the performance of a data store in one metric, Social Action Rating (SoAR). SoAR is defined as the highest throughput provided by a data store while satisfying a pre-specified service level agreement, SLA.
