There was a problem hiding this comment.
read_parquet could launch more than one concurrent read task and this assertion would still pass. Is there any easy way to test that the concurrency is enforced?

Yes, planning to add some test similar to est_backpressure_policies.py:test_basic. But good callout.

ray-project#42849) This PR is to add a new `concurrency` parameter for read APIs. The motivation is to allow users to control concurrency for read operator as well, other than map operators. TODO: Add `concurrency` parameter for all read APIs besides `read_parquet` once we agree on the change. Otherwise too many documentation change needs to make.
