架构图

架构描述

该解决方案会部署如下资源:

1.数据迁移服务 CDM:高效、易用的批量/增量数据迁移和同步服务,提供了40+数据源到数据湖仓的集成能力;

2.数据治理中心 DataArts Studio:提供数据标准和数据模型的规范设计,以及数据分析流程的在线开发、任务编排调度等的一站式数据治理能力;

3.数据湖探索服务 DLI:是一个完全兼容Spakr、FLink生态,支持流处理、批处理、交互式分析的Serverless大数据分析分析服务;

说明:本解决方案以真实数据(脱敏后)为基础,为用户提供配置样例,供用户借鉴参考

数据迁移示例

1.登录华为云云数据库RDS控制台,进入RDS列表,选择业务数据源登录。

图1 登录RDS

2.查看业务数据源"cyz_test"数据库,"t_trade_order"和"t_user_store_info"两张表的基本信息(数据已提前导入),执行SQL获取对应需要在DLI中创建表的语句。

图2 数据库的基本信息

图3 建表结果

3.登录数据湖探索 DLI服务控制台,选择SQL编辑->编辑SQL语句->选择模板自动创建的dgc_dli_test队列->default数据库->单击执行,确保左侧SQL编辑器数据库中表创建成功。

图4 在default数据库中建表

4.登录云数据迁移服务 CDM控制台,选择模板自动创建的集群,单击右侧的作业管理。选择连接管理,单击新建连接,选择数据湖探索(DLI)单击 下一步。

图6 连接管理

图7 数据湖探索

5.填写名称“dli-link”,输入华为云ak、sk(如何获取AK/SK),单击保存。

图8 新建连接

6.单击新建连接,选择“云数据库 MySQL”,填写名称“rds-link”,选择“rds-dgc”源端业务数据库实例,端口“3306”,数据库名称“cyz_test”,用户名/密码,单击保存。 图9 数据库连接

注意:

  1. 首次连接RDS需要上传驱动,点击图中上方的蓝色字体“驱动管理”进行驱动上传,驱动版本参考驱动下载地址。
  2. RDS和CDM在同一个VPC时可以直接连接,否则RDS和CDM均需绑定EIP后使用公网ip,同时RDS安全组添加CDM的入方向规则,放开22号端口,安全组规则添加参考添加安全组规则。

7.(a)选择表/文件迁移,点击新建作业,输入作业名称“t_user_store_info”,作业信息按照下图进行填写。配置完成后单击下一步,字段会自动映射,无需修改,单击下一步,单击保存。

(b)选择表/文件迁移,点击新建作业,输入作业名称“t_trade_order”,作业信息按照下图进行填写。配置完成后单击下一步,字段会自动映射,无需修改,单击下一步,单击保存。

图11 表2作业配置

8.登录数据治理中心 DataArts Studio控制台,选择模板自动创建的实例,选择default工作空间,单击数据开发,在“作业”目录右键,单击新建作业,输入作业名称“dgc_test”作业信息默认即可,单击确定。

图12 新建作业

9.在弹出的界面中选择“节点库”,拖动1个Dummy节点、2个CDM Job节点,按下图填写配置。

图13 CDM job节点1配置

图14 CDM job节点2配置

10.按照截图填好信息后,修改调度信息。单击“保存并提交版本”,单击“执行调度”,单击“测试运行”。

图15 调度配置

图16 执行调度后测试运行

11.执行CDM作业,将RDS的两张表“t_user_store_info”、“t_trade_order”的数据同步到DLI的表中。

图17 数据迁移成功

----结束

数据分析处理示例

1.在完成数据迁移基础上,拖动1个DLI SQL节点到右侧的画布中,按下图填写配置。

图19 DLI SQL节点配置

2.按照截图填好信息后,修改调度信息。单击“保存并提交版本”,单击“执行调度”,单击“测试运行”。
