This is also a correctness problem, not only metrics. A non deterministic DoFn whose outputs feed more than one branch gives each branch a different run, so outputs can be duplicated or lost. #41199 is one case: hot key fanout with a random fanout function computes wrong means in 3 of 3 runs, while a deterministic fanout is correct. -- This is an automated message from the Apache Git Service.
