Airflow 2.10.4 (2024-12-16)
---------------------------
Significant Changes
^^^^^^^^^^^^^^^^^^^
TaskInstance ``priority_weight`` is capped in 32-bit signed integer ranges (#43611)
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Some database engines are limited to 32-bit integer values. As some users reported errors in
weight rolled-over to negative values, we decided to cap the value to the 32-bit integer. Even
if internally in python smaller or larger values to 64 bit are supported, ``priority_weight`` is
capped and only storing values from -2147483648 to 2147483647.

Scarf based telemetry: Airflow now collect telemetry data (#39510)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Airflow integrates Scarf to collect basic usage data during operation. Deployments can opt-out of data collection by
setting the ``[usage_data_collection]enabled`` option to ``False``, or the ``SCARF_ANALYTICS=false`` environment variable.
Datasets no longer trigger inactive DAGs (#38891)
"""""""""""""""""""""""""""""""""""""""""""""""""
Previously, when a DAG is paused or removed, incoming dataset events would still
trigger it, and the DAG would run when it is unpaused or added back in a DAG
file. This has been changed; a DAG's dataset schedule can now only be satisfied
by events that occur when the DAG is active. While this is a breaking change,
the previous behavior is considered a bug.
The behavior of time-based scheduling is unchanged, including the timetable part
of ``DatasetOrTimeSchedule``.
``try_number`` is no longer incremented during task execution (#39336)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Previously, the try number (``try_number``) was incremented at the beginning of task execution on the worker. This was problematic for many reasons.
For one it meant that the try number was incremented when it was not supposed to, namely when resuming from reschedule or deferral. And it also resulted in
the try number being "wrong" when the task had not yet started. The workarounds for these two issues caused a lot of confusion.
Now, instead, the try number for a task run is determined at the time the task is scheduled, and does not change in flight, and it is never decremented.
So after the task runs, the observed try number remains the same as it was when the task was running; only when there is a "new try" will the try number be incremented again.
One consequence of this change is, if users were "manually" running tasks (e.g. by calling ``ti.run()`` directly, or command line ``airflow tasks run``),
try number will no longer be incremented. Airflow assumes that tasks are always run after being scheduled by the scheduler, so we do not regard this as a breaking change.
``/logout`` endpoint in FAB Auth Manager is now CSRF protected (#40145)
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
The ``/logout`` endpoint's method in FAB Auth Manager has been changed from ``GET`` to ``POST`` in all existing
AuthViews (``AuthDBView``, ``AuthLDAPView``, ``AuthOAuthView``, ``AuthOIDView``, ``AuthRemoteUserView``), and
now includes CSRF protection to enhance security and prevent unauthorized logouts.
OpenTelemetry Traces for Apache Airflow (#37948).
"""""""""""""""""""""""""""""""""""""""""""""""""
This new feature adds capability for Apache Airflow to emit 1) airflow system traces of scheduler,
triggerer, executor, processor 2) DAG run traces for deployed DAG runs in OpenTelemetry format. Previously, only metrics were supported which emitted metrics in OpenTelemetry.
This new feature will add richer data for users to use OpenTelemetry standard to emit and send their trace data to OTLP compatible endpoints.
Decorator for Task Flow ``(@skip_if, @run_if)`` to make it simple to apply whether or not to skip a Task. (#41116)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
This feature adds a decorator to make it simple to skip a Task.
Using Multiple Executors Concurrently (#40701)
""""""""""""""""""""""""""""""""""""""""""""""
Previously known as hybrid executors, this new feature allows Airflow to use multiple executors concurrently. DAGs, or even individual tasks, can be configured
to use a specific executor that suits its needs best. A single DAG can contain tasks all using different executors. Please see the Airflow documentation for
more details. Note: This feature is still experimental. See `documentation on Executor <https://airflow.apache.org/docs/apache-airflow/stable/core-concepts/executor/index.html#using-multiple-executors-concurrently>`_ for a more detailed description.

Stackdriver logging bugfix requires Google provider ``10.17.0`` or later (#38071)
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
If you use Stackdriver logging, you must use Google provider version ``10.17.0`` or later. Airflow ``2.9.1`` now passes ``gcp_log_name`` to the ``StackdriverTaskHandler`` instead of ``name``, and this will fail on earlier provider versions.
This fixes a bug where the log name configured in ``[logging] remove_base_log_folder`` was overridden when Airflow configured logging, resulting in task logs going to the wrong destination.

Support for Microsoft SQL-Server for Airflow Meta Database has been removed (#36514)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
After `discussion <https://lists.apache.org/thread/r06j306hldg03g2my1pd4nyjxg78b3h4>`__
and a `voting process <https://lists.apache.org/thread/pgcgmhf6560k8jbsmz8nlyoxosvltph2>`__,
the Airflow's PMC members and Committers have reached a resolution to no longer maintain MsSQL as a
supported Database Backend.
As of Airflow 2.9.0 support of MsSQL has been removed for Airflow Database Backend.
A migration script which can help migrating the database *before* upgrading to Airflow 2.9.0 is available in
`airflow-mssql-migration repo on Github <https://github.com/apache/airflow-mssql-migration>`_.
Note that the migration script is provided without support and warranty.
This does not affect the existing provider packages (operators and hooks), DAGs can still access and process data from MsSQL.
Dataset URIs are now validated on input (#37005)
""""""""""""""""""""""""""""""""""""""""""""""""
Datasets must use a URI that conform to rules laid down in AIP-60, and the value
will be automatically normalized when the DAG file is parsed. See
`documentation on Datasets <https://airflow.apache.org/docs/apache-airflow/2.9.0/authoring-and-scheduling/datasets.html>`_ for
a more detailed description on the rules.
You may need to change your Dataset identifiers if they look like a URI, but are
used in a less mainstream way, such as relying on the URI's auth section, or
have a case-sensitive protocol name.
The method ``get_permitted_menu_items`` in ``BaseAuthManager`` has been renamed ``filter_permitted_menu_items`` (#37627)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Add REST API actions to Audit Log events (#37734)
"""""""""""""""""""""""""""""""""""""""""""""""""
The Audit Log ``event`` name for REST API events will be prepended with ``api.`` or ``ui.``, depending on if it came from the Airflow UI or externally.
Official support for Python 3.12 (#38025)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
There are a few caveats though:
* Pendulum2 does not support Python 3.12. For Python 3.12 you need to use
`Pendulum 3 <https://pendulum.eustace.io/blog/announcing-pendulum-3-0-0.html>`_
* Minimum SQLAlchemy version supported when Pandas is installed for Python 3.12 is ``1.4.36`` released in
April 2022. Airflow 2.9.0 increases the minimum supported version of SQLAlchemy to ``1.4.36`` for all
Python versions.
Not all Providers support Python 3.12. At the initial release of Airflow 2.9.0 the following providers
are released without support for Python 3.12:
* ``apache.beam`` - pending on `Apache Beam support for 3.12 <https://github.com/apache/beam/issues/29149>`_
* ``papermill`` - pending on Releasing Python 3.12 compatible papermill client version
`including this merged issue <https://github.com/nteract/papermill/pull/771>`_
Prevent large string objects from being stored in the Rendered Template Fields (#38094)
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
There's now a limit to the length of data that can be stored in the Rendered Template Fields.
The limit is set to 4096 characters. If the data exceeds this limit, it will be truncated. You can change this limit
by setting the ``[core]max_template_field_length`` configuration option in your airflow config.
Change xcom table column value type to longblob for MySQL backend (#38401)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Xcom table column ``value`` type has changed from ``blob`` to ``longblob``. This will allow you to store relatively big data in Xcom but process can take a significant amount of time if you have a lot of large data stored in Xcom.
To downgrade from revision: ``b4078ac230a1``, ensure that you don't have Xcom values larger than 65,535 bytes. Otherwise, you'll need to clean those rows or run ``airflow db clean xcom`` to clean the Xcom table.
Stronger validation for key parameter defaults in taskflow context variables (#38015)
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
As for the taskflow implementation in conjunction with context variable defaults invalid parameter orders can be
generated, it is now not accepted anymore (and validated) that taskflow functions are defined with defaults
other than ``None``. If you have done this before you most likely will see a broken DAG and a error message like
``Error message: Context key parameter my_param can't have a default other than None``.
