Why Delayed Double Delete Fails: A Hierarchical Java Design for MySQL‑Redis Consistency

The article analyzes why MySQL and Redis cannot guarantee strong consistency with simple cache‑aside patterns, explains the pitfalls of delayed double delete, and presents a tiered Java design—including transaction‑after‑commit deletion, retryable invalidation, CDC/Outbox pipelines, TTL safeguards, and multi‑level cache considerations—to achieve reliable cache consistency.

When a Java application that uses Spring’s @Scheduled moves from a single server to a cluster, the same job may execute on every node, causing duplicate orders, messages, and data; the article explains why this happens, examines common lock‑based fixes and their pitfalls, and proposes a robust, idempotent, sharded task architecture.
