kaxil opened a new pull request, #56790:
URL: https://github.com/apache/airflow/pull/56790
This change adds 83 compatibility imports to the common.compat provider to
help users migrate from Airflow 2.x to Airflow 3.x. The imports cover commonly
used classes including hooks, sensors, operators, decorators, models,
exceptions, assets, and utilities.
Key features:
- Lazy imports using `__getattr__` to avoid loading unnecessary modules
- Multi-fallback support: tries Airflow 3 paths first, falls back to Airflow
2
- Type stubs (.pyi) for full IDE autocomplete support
- Prek hook to keep type stubs in sync with import map
- Optional import validation for developers with full Airflow installed
Users (or Provider Authors/Maintainers) can now import `from
airflow.providers.common.compat.lazy_compat`:
```
from airflow.providers.common.compat.lazy_compat import (
BaseHook,
BaseOperator,
PythonOperator,
DAG,
task,
)
```
This enables DAG code to work seamlessly across both Airflow 2.10+ and 3.x
without modification, supporting phased migration strategies.
