But maybe this solution using UUID s could be the solution without polluting configuration options.

Believe me, we’re not using XML mapping because we like it 😑 It’s just the only solution for dynamic mapping (yes, it’s dynamic). Also, I don’t really want to expose these entity types as API, because that will get in the way of future evolutions. There’s a middle ground to be found between flexibility for Hibernate Search users and flexibility for Hibernate Search developers. You can already change the XML mapping yourself if you want, through configuration properties. Though that’s completely unsupported and could break at any time: see org.hibernate.search.mapper.orm.coordination.outboxpolling.cfg.spi.HibernateOrmMapperOutboxPollingSpiSettings#OUTBOXEVENT_ENTITY_MAPPING.

This looks like an alternative solution to the same problem as https://hibernate.atlassian.net/browse/HSEARCH-4678 ( https://hibernate.atlassian.net/browse/HSEARCH-4678 ).

I suppose we could do both (allow UUIDs or sequences with a large increment size), but I’d like to avoid an explosion of the amount of setups in the wild, which would cause us much trouble when testing. So I’d really like to find one solutions that satisfies everyone, if possible… ( https://hibernate.atlassian.net/browse/HSEARCH-4678#add-comment?atlOrigin... ) Add Comment ( https://hibernate.atlassian.net/browse/HSEARCH-4678#add-comment?atlOrigin... ) Get Jira notifications on your phone!

by Sanne Grinovero (JIRA)

Sanne Grinovero ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiMmUzOWRmZWY4... ) / Improvement ( https://hibernate.atlassian.net/browse/HHH-15598?atlOrigin=eyJpIjoiMmUzOW... ) HHH-15598 ( https://hibernate.atlassian.net/browse/HHH-15598?atlOrigin=eyJpIjoiMmUzOW... ) Remove unused legacy SPIs: InstrumentedClassLoader, ByteCodeHelper ( https://hibernate.atlassian.net/browse/HHH-15598?atlOrigin=eyJpIjoiMmUzOW... ) Issue Type: Improvement Assignee: Unassigned Created: 12/Oct/2022 01:12 AM Fix Versions: 6.2.0 Priority: Major Reporter: Sanne Grinovero ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) The org.hibernate.bytecode.spi.InstrumentedClassLoader is a little utility we don't use ourselves anymore. It's simple enough that anyone needing such a thing could re-implement it themselves so I suggest we remove it. Same for org.hibernate.bytecode.spi.ByteCodeHelper : it has no use within our own runtime code, but it's used by tests - so I'd move it to the testing utilities. Since these are SPIs I’m proposing the change for 6.2, without need for a deprecation cycle. I’ll send a draft to check if this is agreeable.
