[GitHub] [airflow] ashb opened a new pull request #19710: Speed up webserver start up in Kube tests
ashb opened a new pull request #19710:
URL: https://github.com/apache/airflow/pull/19710
Thanks to a previous change (https://github.com/apache/airflow/pull/19709) to not load provider hooks too early we can take advantage of the "preload-app" feature of Gunicorn to load the application once in the main gunicorn process before the workers are forked off.
This change makes the webserver start up (time to serving first request) go from 20s to 5s.
(The reason we don't just do this blindly everywhere is that it would mean plugins are loaded at start only, and is a change in behaviour. But in tests this is fine.)

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.
