It looks like its a pre-existing issue related to passing a large input (order 1000 elements) through test_batch_pardo in order to trigger a flush. I can reproduce the flake in a pipeline that doesn't have a batched DoFn: ``` def test_large_input_pardo(self): with self.create_pipeline() as p: res = ( p | beam.Create(np.array(range(5000), dtype=np.int64)).with_output_types(np.int64) | beam.Map(lambda e: e * 2) | beam.Map(lambda e: e + 3)) assert_that(res, equal_to([(i * 2) + 3 for i in range(5000)])) ``` It's worth noting I haven't seen the flake in a cython environment. Perhaps it's a bug in the "slow" stack which is often only tested with trivial inputs? I don't think I'll be able to diagnose the existing issue today. A solution for this PR might be to skip the flush-triggering test in non-cythonized environments. -- This is an automated message from the Apache Git Service.
