混合异构数据源关联计算优化方案

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 在报表项目中，报表数据源常常会来自于多种异构数据源，例如：关系型数据库（oracle、db2、mysql）、nosql 数据库（mongodb）、http 数据源、hadoop（hive、hdfs），甚至是 excel 或者文本文件。针对这类情况，通常的做法是采用 ETL 工具，将这些数据源都同步到数据仓库中再进行计算。不过这种做法存在以下问题： 1、配置复杂，难度较大； 2、成本较高； 3、数据无法实时访问，时间延迟较长； 4、数据仓库的建设和管理都比较复杂； 5、如果数据量很大效率会很低，而且要不断的 ETL 各个应用系统的同步数据； 6、数据仓库利用的也是传统数据库的技术，负载增大的时候需要用较高的成本进行扩容。 和这种传统做法相比，采用润乾报表可以简单直接地实现混合数据源报表，具体做法是通过内置的集算引擎直接读取各种混合数据源，让数据采用最合适的方式存储，最终以较小的成本呈现基于混合数据源的实时报表。ETL 方式和润乾报表方式在体系结构上的对比如下图所示： 下面，通过《州销售人员销售报表》的设计制作来看一下具体的实现步骤。报表如下图： 报表的销售数据来自于销售系统的 mongodb 数据库，销售员的信息则来自人力资源系统的 db2 数据库。采用润乾报表的混合数据源方式，报表数据源不需要定期同步
