E-commerce Product Ranking System Migration: Technical Implementation and Storage Optimization

The article describes how an e‑commerce product ranking system was migrated to the new “Liao Yue” platform, decoupling it from the search module, introducing fresh metrics and Elasticsearch‑based sorting, then optimizing storage by separating B‑end and C‑end data—cutting costs 60%—with a gray‑scale rollout, dual‑read validation, rollback safeguards, and completing the two‑week, zero‑failure migration that delivered a closed‑loop, faster iteration system.

Stable System Architecture Upgrade: Interface and Data Migration Strategy

The article outlines a proxy‑based migration framework that enables stable system architecture upgrades by using total and gray‑scale switches to achieve gradual rollout, rollback, non‑intrusive business logic, and graceful shutdown, while handling single‑query routing, multi‑query deduplication, double‑write updates, and direct inserts, illustrated with AspectJ‑driven code and retail store‑ID examples.
