Issue Type: Improvement Affects Versions: 5.4.15 Assignee: Unassigned Created: 12/May/2020 10:57 AM Priority: Minor Reporter: Erik ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A591235db-57c4-45b1-a52d-208c47f92323 )

Bulk updates using queries or the criteria API can be used to avoid fetching an entity before executing the update. For example:

UPDATE User u SET u.deleted = true WHERE u.id = :id

In this case, the only modified entity is known, and the entity in question could be manually evicted from the second level cache.

Instead, the whole cache region is evicted through a BulkOperationCleanupAction , and I have not been able to find a workaround for this. Currently it seems like it'd require modifying the EntityPersister itself, as this is where the affected regions are taken from.
