Use Redisson locks safely in Spring Boot by choosing the right transaction boundary, understanding watchdog and lease behavior, enforcing idempotency, and adding fencing tokens for stale lock holders.- Published on
Design a reliable cache-aside flow with PostgreSQL as the source of truth, durable Kafka change events, correct consumer-group topology, version-aware Redis invalidation, TTL fallback, and protection against stale cache refills.- Published on
Choose Redis data structures deliberately in Spring Boot, implement atomic sliding-window rate limits, recover Redis Stream consumers, share web sessions, build leaderboards and approximate counters, and operate Redis without turning it into an accidental source of truth.
