# 1. This prevents the downstream nodes from queuing up incoming images and data

# excessively, which leads to increased latency and memory usage, unwanted in
|
||
|
|
# real-time mobile applications. It also eliminates unnecessarily computation,
|

|
|
# e.g., the output produced by a node may get dropped downstream if the
|
||
|
|
# subsequent nodes are still busy processing previous inputs.
