Why We Abandoned Microservices: Lessons from Scaling a High‑Throughput Event Pipeline

The article recounts how a fast‑growing event‑processing platform initially embraced microservices, then faced queue bottlenecks, test‑suite overload, and operational complexity, leading the team to consolidate over 140 services into a single, shared‑queue architecture, and shares the practical insights and trade‑offs learned from this transition.

Task Distribution Challenges and Solutions in a Small Court System

The article examines backlog, abnormal and over‑consumption problems in a small court’s task distribution, proposes an active‑claim model with user‑task lock queues to decouple qualification checks, and shows that these changes raise completion to 100%, cut processing time from 20 hours to under 2 hours while recommending a factory‑plus‑strategy architecture for future extensibility.
