https://hibernate.atlassian.net/browse/HHH-14544?atlOrigin=eyJpIjoiYmVkZG...
) Since the very beginnings of Hibernate the timestamps cache received invalidations whenever a query is executed. See
https://github.com/hibernate/hibernate-orm/blob/d8d6d82e30960e0c255950eaf...
(
https://github.com/hibernate/hibernate-orm/blob/d8d6d82e30960e0c255950eaf...
) Your frequent writes to disk are a probably due to a misconfiguration. The timestamps cache should not be configured to store on disk but should stay in-memory. (
