Caching (first-level, second-level, query cache) Explain first-level (session) cache is per persistence context and automatic. Second-level cache (e.g., Ehcache, Infinispan) can reduce DB load for frequently-read immutable data; however, caching introduces complexity with invalidation and consistency. Query cache can help repeated query results but must be used cautiously. Cache only when data change frequency and staleness tolerance allow. Which handles your data layer
