🔗 SFQ: Simple, Stateless, Stochastic Fairness

Stochastic Fairness Queuing (SFQ) offers a method to effectively manage workloads in distributed systems by utilizing a fixed set of queues. By hashing customer identifiers to this limited number of queues, SFQ mitigates the negative impact of noisy neighbors while maintaining O(1) performance for both enqueueing and dequeueing requests.

The proposal combines SFQ with shuffle sharding and a best-of-two algorithm to optimize request handling further. This approach enhances customer isolation from noisy neighbors, ensuring that service degradation does not persist, even during resource contention.
