How to Scale an Integration Pipeline Without Breaking Correctness

The article describes a real‑world case of scaling an enterprise integration pipeline from 500 to 8,000 events per second. It emphasizes that during this throughput increase, two correctness guarantees were strictly maintained and never compromised. The post illustrates how to achieve high performance while preserving essential data integrity constraints.

Decoupling Readiness from Release for Tail-Aware Scheduling of Agentic LLM Workflows

The paper introduces a tail‑risk‑aware scheduling strategy for agentic LLM workflows that decouples readiness from immediate release of model turns. By jointly selecting which ready turn to release and controlling the amount of unfinished work kept in the queue, the method uses a mean‑CVaR objective to adapt to evolving tail risk and online turn‑work estimates. Experiments on real software‑engineering task traces show comparable performance to eager release under light load and a significant reduction in the 95th‑percentile workflow flow time, achieving up to a 3.5× speedup under contention.
