支持海量数据可扩展性的需求并非只与Hadoop基础架构的出 现有关。多年来，领先的数据仓库供应商（如IBM和Teradata） 和领先的数据集成平台（如IBM ® InfoSphere ® Information Server）纷纷提供可支持海量数据可扩展性的非共享大规模并 行软件平台，有些企业采用此做法已有近20年。 久而久之，这些供应商陆续集中关注4个常见的软件架构特征， 以便为 重要。没 有它们，该平台将无法处理大量的大数据。 InfoSphere Information Server数据集成产品组合 支持4大海量数据可扩展性架构特征。请在Forrester报 告“Measuring The Total Economic Impact Of IBM InfoSphere Information Server”中了解更多信 息：http://ibm.co/UX1RqB 2)非共享大规模可扩展ETL平台（如IBM InfoSphere Information Server提供的平台） 3)MapReduce ETL pushdown功能 需要同时具备全部三大组件，因为如果不进行手动编码， 大部分数据集成逻辑将无法推送到MapReduce，因为 MapReduce存在很多已知的性能限制。 关键成功因素：考虑数据集成工作负载处理速度 InfoSphere Information Server非共享大规模并行
