FlinkJob场景的LakeFormation授权
提交FlinkJob作业前，需通过委托完成LakeFormation的IAM细粒度授权和SQL资源授权（包括元数据、数据库、表、列和函数），以确保作业在Flink集群后台运行时能够正常访问所需数据。本节介绍FlinkJob场景的LakeFormation授权的具体操作。
授权操作
在使用LakeFormation资源前需要分别完成LakeFormation API的授权和LakeFormation SQL资源授权。各SQL语句的权限请参考Paimon和Iceberg。
- 通过委托，授权使用LakeFormation API。
使用FlinkJob执行作业时，需要您先在IAM页面创建相关委托，并在配置作业时添加新建的委托信息。委托权限示例请参考创建自定义委托。
- LakeFormation SQL资源授权：授权使用LakeFormation具体资源。
LakeFormation资源授权是指允许用户对特定资源（元数据、数据库、表、列和函数等）的访问权限，以此来控制对LakeFormation的数据和元数据的访问。
在LakeFormation管理控制台，对资源授权。FlinkJob支持角色和委托两种主体类型。
了解LakeFormation SQL资源权限请参考配置LakeFormation元数据权限。
SQL鉴权
- 除了表格内的权限，IAM侧还需要配置lakeformation:policy:describe。
- 由于Flink默认会校验default数据库，所以在执行任何SQL前，需要在LakeFormation控制台上先为目标Catalog下的default数据库授予DESCRIBE权限，授权操作请参考配置LakeFormation元数据权限。
- 建议不要给lakeformation:policy:create权限，给了会被视为管理员，跳过SQL鉴权。
