ashb opened a new pull request #21614: URL: https://github.com/apache/airflow/pull/21614
The last remaining step to get (simple) Mapped tasks running in the scheduler was to expand the unmapped TIs when necessary. The interface of `MappedOperator.expand_mapped_task` is not right, and will be changed shortly, but this is enough to get work on the UI and APIs unblocked. Since there are a lot of moving parts in mapped tasks I have created the tests as "integration"/"end-to-end" tests rather than pure unit tests, and marked them as long_running (even if they only take sub 20s right now.) <!-- Thank you for contributing!
