As developers, we strive to create high-performance applications that can handle large amounts of data and provide a seamless user experience. One crucial aspect of achieving this goal is efficient data persistence. In this article, we'll explore the world of high-performance Java persistence, focusing on the best practices, techniques, and tools to help you optimize your data access layer. high-performance java persistence pdf 20
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.
