Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiNzUxMTdlNTA3... ) / New Feature ( https://hibernate.atlassian.net/browse/HHH-15086?atlOrigin=eyJpIjoiNzUxMT... ) HHH-15086 ( https://hibernate.atlassian.net/browse/HHH-15086?atlOrigin=eyJpIjoiNzUxMT... ) Configurable query cache structure layout ( https://hibernate.atlassian.net/browse/HHH-15086?atlOrigin=eyJpIjoiNzUxMT... ) Change By: Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) In 6.0 we changed the query cache structure so that it contains all the data, whereas in 5.x a cache value for an entity stored only the PK value. Both approaches have advantages and disadvantages, so we should try to provide a way to configure how the cache for an entity should be structured. When we have that, we should enable the test {{org.hibernate.orm.test.jpa.query.CachedQueryTest#testCacheableQuery}} We should always use the shallow layout for entities/associations that use reference caching.
