Description

For DAG authors familiar with writing Python functions to do "something", the @task decorator is one of the most popular tools authoring logic in Airflow. There are several other decorators, such as @task.bash, @task.kubernetes, etc. that extend this functionality. However, there is no @task.sql decorator.

This PR introduces the @task.sql decorator. This decorator is a wrapper around the SQLExecuteQueryOperator. However, the value returned from the Python function is the SQL query that is executed.

Here's an example usage:

fromairflow.sdkimportDAG, taskfromdatetimeimportdatetimewithDAG(
dag_id="sql_deco",
start_date=datetime(2025, 1, 1),
schedule="@once"
) asdag:
@task.sql(conn_id="task-sql-decorator"# Transient connection defined in the UI )deftask_1():
return"SELECT 1;"task_1()

Testing

To run the unit tests that were authored for this decorator, the command below can be used:

breeze testing providers-tests providers/common/sql/tests/unit/common/sql/decorators/test_sql.py

The DAG above was also used to validate the functionality of the @task.sql decorator.

Other Notes

There will be additional documentation and examples that comes out of this initial pull request, with the goal of providing parity between this new decorator and the SQLExecuteQueryOperator. For now, this PR just provides the bare-bones.

There is openlineage integration that starts Marquez I believe.

Looks good, thanks !

From the OL perspective, the Ol methods from SqlExecuteQueryOperator are executed, since PythonOperator does not have them. With the added type check in BaseSqlOperator's OL method, the *_on_start method does nothing, since we do not know SQL text before execution, and the *_on_complete behaves as the query was executed with the usual SqlExecuteQueryOperator which is good.

I was going to look at OpenLineage impl, but @kacpermuda already did this - so I just have a few drive-by comments :)

Description

For DAG authors familiar with writing Python functions to do "something", the @task decorator is one of the most popular tools authoring logic in Airflow. There are several other decorators, such as @task.bash, @task.kubernetes, etc. that extend this functionality. However, there is no @task.sql decorator.

This PR introduces the @task.sql decorator. This decorator is a wrapper around the SQLExecuteQueryOperator. However, the value returned from the Python function is the SQL query that is executed.

Here's an example usage:

fromairflow.sdkimportDAG, taskfromdatetimeimportdatetimewithDAG(
dag_id="sql_deco",
start_date=datetime(2025, 1, 1),
schedule="@once"
) asdag:
@task.sql(conn_id="task-sql-decorator"# Transient connection defined in the UI )deftask_1():
return"SELECT 1;"task_1()

Testing

To run the unit tests that were authored for this decorator, the command below can be used:

breeze testing providers-tests providers/common/sql/tests/unit/common/sql/decorators/test_sql.py

The DAG above was also used to validate the functionality of the @task.sql decorator.

Other Notes

There will be additional documentation and examples that comes out of this initial pull request, with the goal of providing parity between this new decorator and the SQLExecuteQueryOperator. For now, this PR just provides the bare-bones.

From the OL perspective, the Ol methods from SqlExecuteQueryOperator are executed, since PythonOperator does not have them. With the added type check in BaseSqlOperator's OL method, the *_on_start method does nothing, since we do not know SQL text before execution, and the *_on_complete behaves as the query was executed with the usual SqlExecuteQueryOperator which is good.

Description

For DAG authors familiar with writing Python functions to do "something", the @task decorator is one of the most popular tools authoring logic in Airflow. There are several other decorators, such as @task.bash, @task.kubernetes, etc. that extend this functionality. However, there is no @task.sql decorator.

This PR introduces the @task.sql decorator. This decorator is a wrapper around the SQLExecuteQueryOperator. However, the value returned from the Python function is the SQL query that is executed.

Here's an example usage:

fromairflow.sdkimportDAG, taskfromdatetimeimportdatetimewithDAG(
dag_id="sql_deco",
start_date=datetime(2025, 1, 1),
schedule="@once"
) asdag:
@task.sql(conn_id="task-sql-decorator"# Transient connection defined in the UI )deftask_1():
return"SELECT 1;"task_1()

Testing

To run the unit tests that were authored for this decorator, the command below can be used:

breeze testing providers-tests providers/common/sql/tests/unit/common/sql/decorators/test_sql.py

The DAG above was also used to validate the functionality of the @task.sql decorator.

Other Notes

There will be additional documentation and examples that comes out of this initial pull request, with the goal of providing parity between this new decorator and the SQLExecuteQueryOperator. For now, this PR just provides the bare-bones.

Looks good to me but worth checking how OL works with it.

There is openlineage integration that starts Marquez I believe.

Looks good, thanks !

From the OL perspective, the Ol methods from SqlExecuteQueryOperator are executed, since PythonOperator does not have them. With the added type check in BaseSqlOperator's OL method, the *_on_start method does nothing, since we do not know SQL text before execution, and the *_on_complete behaves as the query was executed with the usual SqlExecuteQueryOperator which is good.

I was going to look at OpenLineage impl, but @kacpermuda already did this - so I just have a few drive-by comments :)
