Redis is a high-performance, in-memory key-value database. According to official test reports, it can support around 100,000 QPS (queries per second) on a single machine. However, Redis uses a single-threaded architecture in its design.Why does Redis still have such high performance with a single-threaded design? Wouldn't it be better to use multiple threads for concurrent request processing?In this article, let's explore why Redis has a single-threaded architecture and still maintains its speed. The focus is on the following four aspects:Data storage in memoryEfficient data structuresSingle-t...
