    Frequently Asked Questions About Airflow

    Why am I seeing a TemplateNotFound error in Airflow?

    A TemplateNotFound error is usually caused by not properly passing the path to an operator that triggers Jinja templating. This error commonly occurs with BashOperators. To resolve this, make sure files are resolved relative to the pipeline file's location or add other directories to the template_searchpath of the DAG object.

    How can I trigger a task on the failure of another task in Airflow?

    You can use Trigger Rules to trigger tasks based on another task's failure. For example, ALL_FAILED triggers when all upstream tasks fail, and ONE_FAILED triggers when just one upstream task fails. If the tasks are not related by dependency, you will need to build a custom Operator.

    Why might a task fail with no logs appearing in the Airflow UI?

    A task may fail with no logs in the UI if the task's worker was unable to write logs. This can also occur if tasks get stuck in queued status.

    How can I improve DAG file parsing performance in Airflow?

    You can set the file_parsing_sort_mode to modified_time and raise the min_file_process_interval to speed up the parsing of new files. However, this might not work if the DAG is created from a separate file.

    Is it recommended to place multiple DAGs in one file?

    It's not recommended to put multiple DAGs in the same file. It is also advised not to write code outside of defining Airflow constructs.
