这么多问题
图 1-1：大数据可能会让人难以招架
数据分散在各个孤岛上，对有些数据的查询无法满足分析所需的必要性能。其他系统则
将数据存储在单一庞大的系统上，因而不能像现代的云应用程序一样横向扩展。没有这
些能力，你就只能缩小潜在的使用场景和减少用户数量，因此降低了数据的实用价值。
对全世界的组织来说，创建和维护大型专用数据仓库的传统方法成本高昂。通常，对很
多用户和使用模式来说，这种方法也显得缓慢且笨拙。通常被考虑作为解决方案的数据
湖，要么成了无人问津的数据倾倒场，要么需要带着巨大的痛苦艰难地尝试才能对它做数
据分析。作为新方法的数据湖仓，尽管它可以融合数据仓库和数据湖两者的优点，但也不
是唯一的解决方案。数据将持续分布，存储在各个地方，并将出现越来越多的系统。
显而易见的是，一个系统如果可以释放所有这些价值，将会带来巨大的机会。
