potiuk opened a new pull request, #31163:
URL: https://github.com/apache/airflow/pull/31163
When a provider package depends on new version of another provider that
might not yet been released, we have to make sure that this provider is part of
the chunk that is being installed in parallell runs, otherwise the installation
might fail due to a conflict as the pip version of the provider will not be
found.
This PR fixes it by adding directly downstream providers to the chunk that
is being installed. It also handles two edge cases:
1) when number of providers is lower than parallelism we only launch
as many parallel processes as we have providers
2) when number of providers is 0, we short-circuit the installation
immediately.
