 Streams backpressure can optimize throughput while limiting processing and memory consumption by pausing data production as early as possible in a data pipeline.

 This algorithm is defined so that transforms can be updated dynamically.
 There is no guarantee on which frame will happen the switch from the previous transform to the new transform.
