Cache Selection and Usage Guidelines for Ximalaya Services

Ximalaya’s cache guidelines define four Redis‑based types (master‑slave, Codis‑Redis, Cloud Database Redis, XCache) with cache or store modes, prescribe using Cloud Redis for clusters and XCache for large KV, enforce short readable keys, TTLs, limited batch sizes, safe commands, isolated clusters, and compression to ensure stability and performance.
