Backpressure

Section titled “Backpressure”

Backpressure is feedback from a constrained consumer to its producers that limits how quickly more work enters the system.

It prevents an overloaded stage from accumulating work without bound. Common mechanisms include bounded queues, flow control, and admission limits.

Backpressure delays or rejects work before uncontrolled queue growth turns capacity pressure into extreme latency or resource exhaustion.

Load shedding and backpressureKeep overload bounded by slowing producers, limiting admitted work, or rejecting work before saturated components collapse.
