[hibernate-issues] [JIRA] (HHH-16086) Avoid collection recreation when element component contains nullable columns

Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiM2NmMThjMTgz... ) / Improvement ( https://hibernate.atlassian.net/browse/HHH-16086?atlOrigin=eyJpIjoiM2NmMT... ) HHH-16086 ( https://hibernate.atlassian.net/browse/HHH-16086?atlOrigin=eyJpIjoiM2NmMT... ) Avoid collection recreation when element component contains nullable columns ( https://hibernate.atlassian.net/browse/HHH-16086?atlOrigin=eyJpIjoiM2NmMT... ) Issue Type: Improvement Assignee: Unassigned Components: hibernate-core Created: 24/Jan/2023 02:58 AM Fix Versions: 6.wishlist Priority: Major Reporter: Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) It seems that in org.hibernate.collection.spi.AbstractPersistentCollection#needsRecreate we currently force a recreate when the element type contains nullable columns, because the update/delete restriction for these columns would require special care for nullable columns, which we don’t have yet. We prototyped how this could work as part of https://github.com/hibernate/hibernate-orm/pull/5948 ( https://github.com/hibernate/hibernate-orm/pull/5948 ) though, so at some point we should try to get back to this and handle nullable columns properly.
