Caching

Add a cache only with clear freshness and access rules

Measure the repeated read before adding caching. Define the key, lifetime, invalidation behavior, memory limit, and authorization scope. Reference data and user-specific records may require different keys and lifetimes.

A catalog cache-layer preview is not proof of a released 4.0-compatible cache component. Use the actual cache implementation selected by your application, and test stale data, updates, tenant/user separation, eviction, and unavailable cache behavior.
