josh-fell opened a new pull request #16870:
URL: https://github.com/apache/airflow/pull/16870
Related to #10285
- Removed or refactored the `default_args` pattern where necessary as
requested by @ashb (i.e. removed a separated `default_args` declaration for
deference for declaration as part of the `DAG` object)
>**Note:** There are several instances where the `xcom_pull()` call was not
updated. These instances involve accessing a specific value within the `XCom`
or calling user-defined macros with an `XCom` value. Reference #16618 for an
open issue to enhance the `XComArg` functionality to provide similar behavior
as the classic `xcom_pull()` method.
> **Note:** Not all DAGs were tested functionally (i.e. with hard
integrations to source systems and executed), however each DAG was tested to
compile and generate a DAG graph as expected locally.
An detailed summary of all changes made as part of this PR can be found
below:
| DAG File | Converted `xcom_pull()`? | Other Updates? | Comments |
| ---------| ------------------------ | -------------- | -------- |
| airflow/providers/cncf/kubernetes/example_dags/example_kubernetes.py | No
| Yes | Current `XComArg` object does not support accessing specific values of
an iterable `XCom` value elegantly. Did not update this occurrence:<br/>`"echo
\"{{ task_instance.xcom_pull('write-xcom')[0] }}\""`. <br/><br/>Removed
unneeded `default_args` pattern. |
| airflow/providers/cncf/kubernetes/example_dags/example_spark_kubernetes.py
| No | Yes | Current `XComArg` object does not support accessing specific
values of an iterable `XCom` value elegantly. Did not update this
occurrence:<br/>`"{{
task_instance.xcom_pull(task_ids='spark_pi_submit')['metadata']['name'] }}"`.
<br/><br/>Refactored `default_args` pattern. |
