如何运行一个气流任务及其所有依赖项？ [英] How to run one airflow task and all its dependencies?

问题描述

我怀疑

气流运行dag_id task_id执行日期

将运行所有上游任务，但不会。当看到并非所有相关任务都在运行时，它将简单地失败。如何运行特定任务及其所有依赖项？我猜这是由于气流设计的决定而无法实现的，但是有办法解决吗？

would run all upstream tasks, but it does not. It will simply fail when it sees that not all dependent tasks are run. How can I run a specific task and all its dependencies? I am guessing this is not possible because of an airflow design decision, but is there a way to get around this?

推荐答案

您可以通过使用-i / -I / -A标志以及run命令来独立运行任务。

You can run a task independently by using -i/-I/-A flags along with the run command.

但是是的，气流设计不允许运行特定任务及其所有依赖项。

But yes the design of airflow does not permit running a specific task and all its dependencies.

您可以通过从DAG中删除无关的任务来回填Dag，以进行测试

You can backfill the dag by removing non-related tasks from the DAG for testing purpose
