Redis Dual-Active Architecture: Hot-Standby, Dual-Write, and Bidirectional Synchronization Comparison

This article compares Redis dual‑active designs—hot‑standby, various dual‑write models, and bidirectional synchronization—showing hot‑standby’s high cost, dual‑write’s latency or consistency trade‑offs, and arguing that a middleware‑driven bidirectional sync, using replication protocols and fixed‑prefix keys to avoid loops, offers the most practical solution.
