How We Fixed Dubbo Thread‑Pool Exhaustion by Tuning Redis Connection Pools

When a high‑traffic Dubbo interface began throwing thread‑pool exhaustion errors, the team traced the issue to Redis request spikes, identified mis‑configured connection‑pool parameters and version‑specific bugs, and applied a series of quick fixes, pool‑size adjustments, and client‑side optimizations that dramatically reduced latency and error rates.

How We Scaled a Free Mask Distribution System to 220k+ Concurrent Users on Alibaba Cloud

During the early COVID‑19 response, a city launched a free‑mask reservation service that faced massive timed traffic, prompting a rapid evolution of its architecture—from a single‑server Nginx/Tomcat setup to a multi‑layer SLB, CDN, read‑write split DB, and finally an ideal CDN‑backed design—while documenting the performance bottlenecks, scaling limits, and concrete tuning steps that enabled a 7‑minute sell‑out.
