[JIRA] (HHH-16710) package multiple selections automatically as Map/List/record

Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZWI1ODU2ZDA0... ) / New Feature ( https://hibernate.atlassian.net/browse/HHH-16710?atlOrigin=eyJpIjoiZWI1OD... ) HHH-16710 ( https://hibernate.atlassian.net/browse/HHH-16710?atlOrigin=eyJpIjoiZWI1OD... ) package multiple selections automatically as Map/List/record ( https://hibernate.atlassian.net/browse/HHH-16710?atlOrigin=eyJpIjoiZWI1OD... ) Issue Type: New Feature Assignee: Unassigned Components: hibernate-core Created: 28/May/2023 08:53 AM Priority: Major Reporter: Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) While working on the docs, I suddenly realized just how silly are the hoops we make you jump through with select new list , select new map , select new Record , etc. We already automatically package your selection as a Tuple if you ask for it, so there’s no reason we can’t do that with these other representations. The explanation of this stuff in the docs got convoluted because there was an inconsistency there, and the code examples were longer than they should have been.

[JIRA] (HHH-16708) Same SQL String for two EntityLoader with different byte Arrays (uncomfortable for GC1 Stringdeduplication)

by sabri boubaker (JIRA)

sabri boubaker ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5d694cb... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiOTA0ODE5ODM0... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16708?atlOrigin=eyJpIjoiOTA0OD... ) HHH-16708 ( https://hibernate.atlassian.net/browse/HHH-16708?atlOrigin=eyJpIjoiOTA0OD... ) Same SQL String for two EntityLoader with different byte Arrays (uncomfortable for GC1 Stringdeduplication) ( https://hibernate.atlassian.net/browse/HHH-16708?atlOrigin=eyJpIjoiOTA0OD... ) Change By: sabri boubaker ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=5d694cb... ) Hello, I have a hibernate application with a huge object graph (over 2000 tables with over 20 columns per table). As known, this will lead to huge memory usage during startup. So I walked over the known tips; configuring the Query plan cache, the default_batch_fetch_size, the batch_fetch_style, and all the stuff. Now, some of my EntityLoaders (within the same singleTableEntityPersister), have exactly the same generated SQL (exactly character by character), so I was looking if Hibernate offers a way to share these Strings (SQL) between EntityLoaders without success. So I used the GC1 StringDeduplication but without gaining too much. The reason seems to be that even if Sql(s) are the same (visually) they do not have the same byte array, and the GC1 won't be able to deduplicate the String and memory still occupied. Can It be related to Encoding when hibernate create the SQl String? No idea. Maybe I'm missing something. PS: I know that there was a big improvement beginning from version 5.2.18 but I created this ticket maybe the same behavior still exists.

[JIRA] (HHH-16606) ClassCastException retrieving byte[] from database

by Čedomir Igaly (JIRA)

Čedomir Igaly ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16606 ( https://hibernate.atlassian.net/browse/HHH-16606?atlOrigin=eyJpIjoiMmQ3NT... ) Re: ClassCastException retrieving byte[] from database ( https://hibernate.atlassian.net/browse/HHH-16606?atlOrigin=eyJpIjoiMmQ3NT... ) Problem is more general, not limited to byte array (or LOB). I’ve re-wrote your test case and created (draft) pull request 6679 ( https://github.com/hibernate/hibernate-orm/pull/6679 ) Cause of the problem is method org.hibernate.query.sqm.internal.ConcreteSqmSelectQueryPlan#determineRowTransformer. It is wrongly for and result of array type selecting RowTransformerArrayImpl. However, in case like this one (when result is single array property) selected row transformer should be RowTransformerSingularReturnImpl. I hope that leter today I will be able to propose solution, or at least starting point to solution.
