Flink流水线+Gravitino+Paimon集成

news 2025/7/8 8:43:00

1.数据源管理

1.1 添加Gravitino数据源

添加成功之后，会在Gravitino中创建一个名为配置的中的meatalake

1.2. 添加Paimon数据源

属性gravitinoId可以关联前面创建的Gravitino数据源，关联后，会在gravitino下创建一个该数据源的catalog。

2. 集成演示

2.1 创建任务

入口：通过顶部菜单栏选择 任务开发，或通过快捷入口 快速创建任务。
任务类型：选择 FlinkPipeline。

2.2 配置任务

点击任务名称，进入任务详情页。任务节点如下

功能说明：

使用DataGen节点生成100条测试数据，使用JDBCWrite将数据写入mysql的user表，再通过JDBCRead读取mysql的user表，使用SQLExecute写入到Paimon。通过SQLQuery读取Paimon,最后通过ShowData节点输入读取的数据。
