potiuk opened a new pull request, #37320:
URL: https://github.com/apache/airflow/pull/37320
We've been internally using pydantic for internal API and it caused some
compatibility issues, because Pydantic is so popular and currently still users
of Pydantic are somewhat split between Pydantic 1 and Pydantic 2. The
popularity of Pydantic works against us, and since we are not yet using it in
"production" (and in the future we will only actually use it for Internal API),
it seems that turning Pydantic into an optional dependency is the best way we
can proceed.
It's as simple as converting all the direct imports into a common util
imports that have a fallback mechanism when import is not found.
This should enable less conflicts when installing 3rd-party libraries with
Airflow.
