Design and implementation of high-performance and high-availability redis client

Abstract： Redis is an unstructured database based on memory storage. It is known for high I/O(Input/Output) performance and high response speed. It plays an important role in data buffering, message queues, key-value storage and other scenarios. Among the many clients it supports, the C/C++ client Hiredis is particularly widely used. This article did an in-depth analysis of the Hiredis library and found that its pipeline function has high overhead, improper instruction storage, and memory confusion problems. Based on this, this article designs and implements a C/C++-oriented high-performance and high-availability Redis client on a 32-core X86 architecture processor and a 64 GB memory Linux server. It improves the performance of processing a large number of instructions and solves the problem of memory confusion in complex scenarios through memory pre-allocation and memory isolation. After testing, the new client has improved instruction execution efficiency by 3～7 times, while also ensuring memory safety and accuracy in complex scenarios.
