Here are some useful points:

• Pay attention to the quality of your code (flake8, mypy and type annotations). Our pre-commits will help you with that.
• In case of a new feature add useful documentation (in docstrings or in docs/ directory). Adding a new operator? Check this short guide Consider adding an example DAG that shows how users should use it.
• Consider using Breeze environment for testing locally, it’s a heavy docker but it ships with a working Airflow and a lot of integrations.
• Be patient and persistent. It might take some time to get a review or get the final approval from Committers.

The PR is likely OK to be merged with just subset of tests for default Python and Database versions without running the full matrix of tests, because it does not modify the core of Airflow. If the committers decide that the full tests matrix is needed, they will add the label 'full tests needed'. Then you should rebase to the latest main or amend the last commit of the PR, and push it with --force-with-lease.

Failing tests and static checks :(

Can you add a reference to this section in Python API reference docs?

airflow/airflow/providers/google/cloud/operators/bigquery.py

Lines 126 to 128 in fb6b2d1

	.. seealso::
	For more information on how to use this operator, take a look at the guide:

The Python API reference docs for the DataprocInstantiateInlineWorkflowTemplateOperator already has a reference (which is broken):

.. seealso::
Please refer to:
https://cloud.google.com/dataproc/docs/reference/rest/v1beta2/projects.regions.workflowTemplates/instantiateInline

So you want me to replace it with this

Or fix the link with this reference?

What do you think about fixing a link AND adding a new reference to our guide?

[potiuk]

It needs some fixes in the list of documentation left.

The PR most likely needs to run full matrix of tests because it modifies parts of the core of Airflow. However, committers might decide to merge it quickly and take the risk. If they don't merge it quickly - please rebase it to the latest main at your convenience, or amend the last commit of the PR, and push it with --force-with-lease.
