Harden queue backpressure design
Hard System Design arena: message queues, retries, dead-letter queues, and flow control
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: system-design-easy-queue-backpressure
An email worker falls behind during campaigns and retry storms amplify the backlog. You are working inside a system design review board, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply message queues, retries, dead-letter queues, and flow control in a system design review board while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates message queues, retries, dead-letter queues, and flow control
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids unsafe dynamic execution
Clear the route first
You can read the mission brief, but the editor, hints, tests, and submit flow stay locked until progression or plan access catches up.
