sqllineage解析FineBI数据集导入Datahub生成血缘
需求
当前数仓架构流程图如下图所示，不支持端到端数据血缘，数据异常排查及影响分析比较被动，需要端到端数据血缘及元数据管理。
业务系统：各种制造业业务系统（高速迭代、重构、新建中）
数仓开发平台：数栖平台，支持数仓内各层级的DAG调度血缘图
数仓导出库：PG
BI可视化系统：FineBI，支持内部数据集、图表的血缘
通过调研分析，引入datahub做元数据管理平台，实现效果如下图展示。
方案
实现如下端到端血缘图：
BI报表/仪表盘（dashboard）->BI组件（chart）->BI数据集->数仓导出库(PG)->数仓数据资产(数栖平台)->上游业务系统
工作内容：
- ✅datahub中自定义FineBI、数栖平台的plateform及图表
- ✅解析FineBI数据库，获取FineBI中BI报表/仪表盘（dashboard）->BI组件（chart）->BI数据集的血缘关系，调用Datahub rest emiter接口，datahub中生成血缘。
- ✅获取BI数据集的SQL代码，通过sqllineage解析BI数据集与数仓导出库(PG)的血缘关系，调用Datahub rest emiter接口，datahub中生成血缘。
- ✅获取数栖平台数据库中工作流、Hive任务的关系，获取Hive任务的SQL代码，通过sqllineage解析SQL代码的血缘，调用Datahub rest emiter接口，datahub中生成血缘。
本文介绍：
- ✅datahub中自定义FineBI、数栖平台的plateform及图表
- ✅通过sqllineage解析SQL生成血缘关系
- ✅调用Datahub rest emiter接口，datahub中生成血缘
前置工作
- 安装Datahub
- 安装sqllineage

# 用 途: 数仓Hive血缘
# 1. 通过Trino查询数据库，获取数栖平台调度DAG血缘关系
# 2. 注意：直接操作数据库修改权限，BI有大概几分钟的缓存时间，需要等待数据更新。
# 3. 注意：fine_pack_filter中create_type=3,是用户角色。使用的rowid = fine_user中的id，在最终用户权限上配置的。
# . 4. "且" = 34；"或"=35
# 5. 依赖数仓中manual开头的表，这些表通过爬虫采集，数据延迟一天
