本文基于Flink SQL与hudi构建准实时数仓，在Flink从kafka接入数据之后，即将所有数据存于hudi中，包括所有中间处理数据以及最终数据。文章《实时数仓|基于Flink1.11的SQL构建实时数仓探索实践 (qq.com)》描述了基于Flink SQL与kafka构建的实时数仓，本文以上述文章为基础。
在完成本文实践的同时可以同步参考上述文章。
最终结果：
背景介绍
本文电商业务为例，展示准实时数仓的数据处理流程。
组件与配置说明
Flink 1.13.3
flink cdc 2.0.2
hudi 0.10.0 （2021.12.08最新发布版本，地址：https://github.com/apache/hudi/releases/tag/release-0.10.0）
hadoop 3.2.0
zeppelin 0.10.0
mysql 5.7（开启binlog）
kafka 2.5.0
由于zeppelin的便捷性，本文全部基于zeppelin进行任务提交，如果您还不会用zeppelin，那么您可以参考：https://lrting-top.blog.csdn.net/article/details/120681666。当然，如果您不想用zeppelin，用Flink SQL Client提交也是完全没有问题的。
本实验Flink开启checkpoint，设置为60s。
在完成以下任务之前，请确保您已经
- 部署好Flink 1.13.3，并将hudi对应的Jar包已经正确打包并且放置到Flink的lib目录下，将flink cdc对应的jar包放置到lib目录下。
- 部署并启动zeppelin 0.10.0，在zeppelin的Flink interpreter上指定了FLINK_HOME以及HADOOP_CLASSPATH
- 同时还有启动hadoop、mysql、kafka
处理流程
MySQL建表与原始数据载入
首先从以下地址获取mysql建表语句以及模拟数据：
https://obs-githubhelper.obs.cn-east-3.myhuaweicloud.com/blog-images/category/bigdata/hudi/flink-hudi-realtime/realtime_table.zip
下载了上述建表语句之后，进入mysql，新建realtime_dw_demo_1，进入数据库 realtime_dw_demo_1 ，初始化数据库
代码语言：javascript复制mysql -u root -p
create database realtime_dw_demo_1;
use database realtime_dw_demo_1;
source realtime_table.sql将mysql表数据同步到kafka
使用flink cdc将mysql数据同步到kafka中，以下为相关sql语句：
读取mysql源表数据
代码语言：javascript复制%flink.ssql
