Hi William, the AsyncOperator does not have such a setting. It is "merely" a wrapper around an asynchronous call, which provides integration with Flink's state & time management.
I think, the way to go would be to do the exponential back-off in the user code and set the timeout of the AsyncOperator to the sum of the timeouts in the user code (e.g. 2s + 4s + 8s + 16s).
