This video is about Hibernate Caching. Hibernate provides 3 levels of caching: First Level , Second Level and Query Cache. First Level cache does not need any setup. Second Level Cache and Query Cache. Query Cache needs second level cache because when query result is obtained from cache hibernate will load objects from second level cache. Second level cache exists as long as session factory is alive. First level cache will always be consulted before any attempt is made to locate an object in second-level cache.
