potiuk opened a new pull request, #37741:
URL: https://github.com/apache/airflow/pull/37741
There were a few small issues with provider metadata:
* new providers that have never been included in constraints got 2.0.0
version of airflow associated
* providers that were present in constraints of several airflow versions got
associated with the "latest" version that got them in constraints
* provider's metadata generation was serialized and took a bit more than a
minute to run - which was pretty slow
This PR fixes all those issues:
* providers which were never included in constraints are added to the first
version of airflow released after the provider version was released
* if there is no version of airflow released yet after provider is released,
the provider got associated with latest released version of airflow
* when provider is present in multiple constraints, provider is associated
with the OLDEST airflow release that had it in constraints
* we are using multiprocessing to run provider metadata retrieval in
parallel - effectively speeding up the retrieval (after airflow versions were
retrieved and constraints refreshed) to less than 10 seconds.
