Apache Airflow Standard Providers

1.12.2 · active · verified Thu Apr 09

This package provides "standard" operators, hooks, and sensors for Apache Airflow. It extends the core Airflow functionality with common components that were historically part of the main `apache-airflow` package before the modularization introduced in Airflow 2.0. The current version is 1.12.2, and providers are released and versioned independently from Airflow core following a Semver scheme, often with more frequent releases than Airflow itself.

Warnings

breaking When upgrading to Airflow 3.x, many core operators and hooks (e.g., `PythonOperator`, `BaseHook`) were moved from `airflow.operators` or `airflow.sensors` directly into specific provider packages, including `apache-airflow-providers-standard`. This requires updating import paths in existing DAGs.
Fix: Update import statements to use the `airflow.providers.standard` path, e.g., `from airflow.providers.standard.operators.python import PythonOperator`.
breaking Support for Python 3.9 was dropped in `apache-airflow-providers-standard` version 1.4.0. Users on Python 3.9 must upgrade their Python environment to `3.10` or newer to use current provider versions.
Fix: Upgrade Python environment to 3.10, 3.11, 3.12, 3.13, or 3.14.
deprecated In Airflow 3.x, custom operators cannot access the Airflow metadata database directly using database sessions. This change improves security and maintainability.
Fix: Use the Airflow Python Client for programmatic interaction with Airflow resources or utilize `DbApiHook` (e.g., `PostgresHook`, `MySqlHook`) if direct database interaction is essential for external systems.
gotcha The minimum Apache Airflow version supported by this provider is 2.11.0. Installing this provider on older Airflow versions may lead to compatibility issues or automatic, potentially breaking, upgrades of the `apache-airflow` package.
Fix: Ensure your Apache Airflow core installation is version 2.11.0 or newer before installing this provider package.

Install

pip install apache-airflow-providers-standard Install latest version

Imports

PythonOperator
```
from airflow.providers.standard.operators.python import PythonOperator
```
Common operators previously in Airflow core moved to `airflow.providers.standard` in Airflow 2+.
BranchDateTimeOperator
```
from airflow.providers.standard.operators.datetime import BranchDateTimeOperator
```
Common operators previously in Airflow core moved to `airflow.providers.standard` in Airflow 2+.
LatestOnlyOperator
```
from airflow.providers.standard.operators.latest_only import LatestOnlyOperator
```
This operator was moved to the standard provider as part of modularization.
ExternalTaskSensor
```
from airflow.providers.standard.sensors.external_task import ExternalTaskSensor
```
This sensor was moved to the standard provider as part of modularization.

Quickstart

This example demonstrates a basic Airflow DAG using the `PythonOperator` provided by the `apache-airflow-providers-standard` package. Ensure you have Apache Airflow installed (`apache-airflow>=2.11.0`) and then install this provider package. The `PythonOperator` allows you to execute an arbitrary Python callable as an Airflow task.
