Will it actually log any outpit :) ? I think not as Dummy Opertor's execute is not well.. executed :)?

[github-actions]

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.

This operator may be too criminal to use in production

Yes the inherits_from_dummy_operator check would kick in to not run execute.

[potiuk]

Yes the inherits_from_dummy_operator check would kick in to not run execute.

Well. Then I think we can't merge it because it DOES NOT WORK AS ADVERTISED!

[potiuk]

Now - you talking to me :)

[potiuk]

But even smooth operator needs some ❤️ when it comes to static checks :D

[potiuk]

Static checks are Sade, ehm SAD.

[potiuk]

Not SADE any more and just random failure. Merging :)

Just in time for 2.3.0.

We could not wait for SmoothOperator. It's been highly requested feature by many.
