   > Is it expected that the `Providers` tests in the "Tests: Always API Core Other CLI Providers Integration" suite doesn't run for MySQL and MSSQL? I was surprised that only Postgres and Sqlite failed.
   
   Yes. That was done as part of stabilizing our flaky CI Tests.
   
   Both MySQL and MSSQL (despite very aggressive optimisation of the configuration of the dockerized versions of those) require much more memory to run than Postgres and SQLite. That lead to Jobs failing quite often when they were run on Public Runners.  That's why they are disabled now for those two databases (but only on Public Runners). 
   
   In fact, it is actually even printed there. If you unfold "Determine how to run the tests" in those tests you will see this:

   You will find the logic controlling it here https://github.com/apache/airflow/blob/906d710060ebfe893ef3d7cddf00d2c49c7998fa/scripts/ci/testing/ci_run_airflow_testing.sh#L68
   
   Also "all" tests will run in "main" after the change is merged. Those tests are run on our 64GB mem self-hosted machines, that have enough CPUS and memory to run all the tests always in parallell. So we will see failing main in case those "Providers" tests run on MySQL or MsSQL woudl fail (which is highly unlikely because Provider tests are not supposed to be "Metadata-DB" dependent. Yet we "just in case" always run all tests in main.
