Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HSEARCH-4708 ( https://hibernate.atlassian.net/browse/HSEARCH-4708?atlOrigin=eyJpIjoiMzZ... ) Re: No automatic reindexing when changing a property annotated with @OneToOne(mappedBy = ...) @IndexedEmbedded ( https://hibernate.atlassian.net/browse/HSEARCH-4708?atlOrigin=eyJpIjoiMzZ... ) You can find the whole conversation there: https://hibernate.zulipchat.com/#narrow/stream/132094-hibernate-orm-dev/t... ( https://hibernate.zulipchat.com/#narrow/stream/132094-hibernate-orm-dev/t... ) The gist of it: * Hibernate ORM used not to trigger any event for changes to a @OneToOne(mappedBy = ...) * it started triggering events in some cases after https://hibernate.atlassian.net/browse/HHH-14216 ( https://hibernate.atlassian.net/browse/HHH-14216 ) was fixed * Hibernate Search has been relying on that new behavior ever since * But https://hibernate.atlassian.net/browse/HHH-14216 ( https://hibernate.atlassian.net/browse/HHH-14216 ) has been causing loads of issues, to such a point that the patch was reverted in https://hibernate.atlassian.net/browse/HHH-15045 ( https://hibernate.atlassian.net/browse/HHH-15045 ) * Moving forward, Hibernate ORM could provide additional events for @OneToOne(mappedBy = ...) , but that would probably be a new event type: JPA specifies that @PostUpdate events are about database updates, so we probably don’t want them to be triggered for @OneToOne(mappedBy = ...). With that in mind, I’ll work on a limited implementation of https://hibernate.atlassian.net/browse/HSEARCH-3567 ( https://hibernate.atlassian.net/browse/HSEARCH-3567 ) , just for non-owning ToOne associations; that should allow us to fix this bug with limited impact on usability and performance.
