Diagram for Backpressure
Executive brief

Backpressure fits when Preventing fast producers from overwhelming slow consumers. Mechanism: Signal producers to slow down, shed load, or buffer within bounded limits. Use it for Streams, queues, APIs, ingestion systems. The toll: Requires a policy for what gets delayed, dropped, or degraded.

Use when

Streams, queues, apis, ingestion systems.

Example

Use backpressure when streams, queues, apis, ingestion systems..

Review framing

Describe the pressure first, then the mechanism, then the cost. That keeps the design grounded.
