Beyond Delayed Double Delete: How CDC Closed‑Loop Governance Solves Cache Consistency
The article dissects why the classic "update‑DB‑then‑delete‑cache" or its reverse is only a probability fix for cache inconsistency, demonstrates the failure modes of delayed double delete under high load and replication lag, and presents a production‑grade solution built on Binlog CDC with versioning, four‑plane governance, and robust error handling to achieve reliable cache synchronization.
