github-actions[bot] opened a new pull request, #45826:
URL: https://github.com/apache/airflow/pull/45826
The DAG serialization tests load all of the example and system test DAGs, and
there were two places that these tests opened connections at parse time
resulting in loads of extra of test time.
- The SystemTestContextBuilder was trying to fetch things from SSM. This was
addressed by adding a functools.cache on the function
- The Bedrock example dag was setting/caching the underlying conn object
globally. This was addressed by making the Airflow connection a global,
rather than the Bedrock conn. This fix is not _great_, but it does
massively
