dbt 的test 还是比较强大的,灵活性也比较多,官方是内置了一些test macro,同时也有不少三方工具包,内部上dbt 会将包含test 的解析为resource_type 为test 同时会生成一些对应的sql 模型(只进行执行的不会实践创建)之后还是会调用macro 实现进行check 处理,同时还是 结合配置的severity策略进行提示,实际上内部处理后边...
test:这个命令用于在已部署的数据模型中运行数据测试,以确保数据的准确性和一致性,基本作用: 验证数据的准确性、完整性和一致性。 验证数据转换逻辑是否正确。 验证数据之间的关系和约束。 举个test 的例子: models: - name: my_model tests: - my_test: severity: error description: "Check if column X cont...
