Design and Performance Optimization of Twemproxy Using Nginx Multi‑Process Architecture

The project re‑engineers Twemproxy by adopting Nginx’s master‑worker multi‑process model, adding non‑blocking accept locks, reuseport load balancing, CPU affinity and crash isolation, which transforms the single‑threaded proxy into a scalable, low‑latency, high‑QPS solution suitable for public‑cloud high‑concurrency workloads.

Case Study: Scaling Redis with Twemproxy and Optimizing Connection Pools

The team rescued a crashing Redis cache handling 100K‑120K QPS by shrinking Nginx Lua timeouts, trimming connection pools, adding four Redis nodes behind Twemproxy, and splitting keys to raise cardinality, which eliminated connection spikes, balanced shard load, and restored stable performance.

Redis Cache Cluster Solutions: Dynomite, Twemproxy, and Codis

Due to the memory limits of single Redis servers, many companies adopt proxy‑based Redis clustering solutions such as Netflix’s Dynomite, Twitter’s Twemproxy, and the open‑source Codis from Wandoujia, which provide distributed caching, cross‑data‑center replication, and improved performance and availability.
