How are cache keys handled in this pattern?

The skill promotes the use of static Key Builder methods within the Cache Service to ensure consistent key naming for entities, lists, and filtered queries.

What version of Lutece does this skill support?

This skill is specifically designed for Lutece 8 and above, utilizing Jakarta EE, CDI patterns, and the latest AbstractCacheableService core features.

Does it support automatic cache invalidation?

Yes, it includes patterns for observing ResourceEvents to automatically reset or update specific cache entries when the underlying data changes.

Where is the cache configuration managed?

Cache settings like TTL and max elements can be configured in caches.properties or overridden dynamically via the Lutece Datastore.

Can I prevent a cache from being cleared by a global reset?

Yes, the skill demonstrates how to override the isPreventGlobalReset method for expensive configuration caches that should persist through admin-initiated resets.

API Development

Standardizes cache implementation for Lutece 8 plugins using CDI-managed services and JSR-107 patterns.

This skill provides a structured framework for implementing high-performance caching layers within Lutece 8 plugins. It guides developers through the creation of CDI-scoped cache services using the AbstractCacheableService base class, ensuring adherence to Lutece core standards. By implementing best practices for key generation, cache-through logic, and event-driven invalidation via Jakarta EE ResourceEvents, this skill helps developers reduce database load and improve application responsiveness while maintaining strict data consistency.
