一、最佳实践背景

整个最佳实践是基于MaxCompute的湖仓一体架构，模拟公司使用场景。比如公司 A 使用云上关系型数据库 RDS 作为自己的业务库，同时使用阿里云 EMR 系统做日志数据采集。将数据汇集到云上对象存储 OSS 上，引入了数据湖常会用的存储机制 Delta Lake 和 Hudi 为数据湖提供流处理、批处理能力。通过 MaxCompute 查询到实时数据，即时洞察业务数据变化。 整个场景demo的架构是，云上EMR产生的实时变化的数据，包括在线数据库RDS，通过数据入湖，然后实时的把数据变化体现在归档的OSS 上。同时MaxCompute跟其他引擎一起分析OSS上的数据。
