My logs are getting completely flooded with useless messages for every heartbeat.

Our logs are now too noisy to be useful. How can we disable these? Changing the log level to something like logging.WARN is not an option because we have lots of actually useful information at the INFO level.
回答1:
Currently, it is not possible to disable it. I have created a PR that changes the log level to DEBUG. Unfortunately, this won't be available until the next release (1.10.7).
The short-time solution would to manually apply the change in the PR to your Airflow installation.
