Michał S ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-14544 ( https://hibernate.atlassian.net/browse/HHH-14544?atlOrigin=eyJpIjoiZmFmND... ) Re: Performance degradation observed with Hibernate 5.4.23 updating timestamps cache when a cacheable hint isn't specified ( https://hibernate.atlassian.net/browse/HHH-14544?atlOrigin=eyJpIjoiZmFmND... ) Thanks for the clarification Christian. It turns out we are using default ehcache configuration which, I guess, could be the problem. We have changed nothing for Hibernate upgrade, and we kept ehcache at 2.x. Maybe it’s how Hibernate configures ehcache by default was the issue. Do I understand correctly that the timestamps cache will be invalidated whether query is cached or not? Anyway thanks for looking into the issue.
