Hello Everyone, Another day, another announcement. I have just merged this PR https://github.com/apache/airflow/pull/22127 that adds support for development for Mac OS M1 users (and also anyone who uses ARM-based linux.
The M1 users have (rightfully) complained about rather poor performance for Dockerized Airflow in Breeze (the intel-based images were used via emulation and suffered roughly ~ 10x slower speed which made them barely usable for development). As of today, our images used for development in Breeze are multi-platform (amd64/arm64). This is - for now - development only and has some limitations (mysql and mssql support is missing until mysql and mssql release arm-based clients and servers - but we have full postgres and sqlite support - including native ARM postgres server Docker image). Some initial teething problems have been fixed (thanks Elad/Ephraim :) but also as a follow up I will need to observe it and implement a few build optimizations (next few days). So if you see any problems, delays etc, ping me on #breeze channel in our slack. Also building ARM images on Intel also suffers from the same 10x slower emulation problems so we need to modify our CI / self-hosted infrastructure, but once we do and once we start testing ARM on CI, we will also be able to release multi-platform "release" images, completing https://github.com/apache/airflow/issues/15635 and opening up Airflow to be used on ARM-based linux. I hope in 2.3.0 we will be able to release the Airflow Production ARM image. J.
