摘要:针对大规模数据分析的mapreduce技术已被广泛意识和研究,我们已经看到了云数据服务系统数量的爆炸性增长。这些新系统是所谓“云OLTP”应用,虽然它们并不支持ACID事务。典型例子如BigTable,PNUTS,Cassandra,HBase,Azure,CouchDB,SimpleDB,Voldemort,等等。而且它们被应用于不同于传统服务工作量的很多领域(如TPC-C)。The number of emerging cloud serving systems and the wide range of proposed applications,coupled with a lack of apples-to-apples performance comparisons,makes it difficult to understand the tradeoffs between systems and the workloads for which they are suited.(新兴的云系统与大范围的其它系统,因为缺乏公平的性能比较,在系统间判断谁更适合其工作量)我们发布了yahoo! Cloud Serving Benchmark (YCSB) 框架,为的是促进新的云数据服务系统的性能比较。我们对四种广泛应用的系统:Cassandra,HBase,Yahoo!'s PNUTS和MySQL的简单实现版定义了关于基准和报表的核心集。通过开源,我们希望其它的
