Understanding Redis String Memory Overhead and Optimization Techniques

This article explains why Redis String types can consume excessive memory, examines the underlying Simple Dynamic String (SDS) structure and its three encoding modes, and demonstrates how using compressed lists (ziplist) and hash‑based storage can significantly reduce memory usage in backend applications.

How Ctrip Optimized Hotel Cache Memory: From HashMap Overhead to Advanced Encoding

Facing billions of cached hotel records, Ctrip’s backend team analyzed Java object layout and HashMap memory costs, evaluated alternative structures, and applied bitmap, dictionary, run‑length and delta encodings to compress data, ultimately reducing cache size to under 2% of its original footprint.
