Cache TTL and Invalidation

Manage expiration and eviction.

Why TTL Matters

Cached data can go stale. A TTL (time-to-live) automatically expires entries after a set duration, bounding how stale data can get.

Setting a Default TTL

Apply a TTL to all caches via the default configuration.

RedisCacheConfiguration config =
    RedisCacheConfiguration.defaultCacheConfig()
        .entryTtl(Duration.ofMinutes(10));
