[JIRA] (HHH-16793) @TableGenerator on MappedSuperclass results in multiple inserts

by Chris Lenz (JIRA)

Chris Lenz ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=70121%3... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZjNiMWY1MmMz... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16793?atlOrigin=eyJpIjoiZjNiMW... ) HHH-16793 ( https://hibernate.atlassian.net/browse/HHH-16793?atlOrigin=eyJpIjoiZjNiMW... ) @TableGenerator on MappedSuperclass results in multiple inserts ( https://hibernate.atlassian.net/browse/HHH-16793?atlOrigin=eyJpIjoiZjNiMW... ) Issue Type: Bug Assignee: Unassigned Components: hibernate-orm-modules Created: 14/Jun/2023 03:18 AM Environment: We are using Quarkus Hibernate ORM version 3.0.3 Final. JavaVersion.VERSION_17 database Postgres 14 Priority: Major Reporter: Chris Lenz ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=70121%3... ) We have @MappedSuperclass @TableGenerator(name = "Entity.Sequence", schema="xxx", table = "sequence", initialValue = 1, allocationSize = 100, pkColumnName = "name", pkColumnValue = "id", valueColumnName = "count") public class AbstractEntity implements Serializable{ and @MappedSuperclass public abstract class VersionableEntity extends AbstractEntity and 3 entities like: @Entity ... public class XXX extends VersionableEntity{ The problem we face is that now the SchemaExporter generates one Schema for the Sequence Table, that's ok, but it generates 3 inserts into the table: insert into xxx.sequence(name, count) values ('id',0); insert into xxx.sequence(name, count) values ('id',0); insert into xxx.sequence(name, count) values ('id',0); ( https://hibernate.atlassian.net/browse/HHH-16793#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16793#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!

[JIRA] (HHH-16779) EntityManager.find(Class<T> entityClass, Object primaryKey) generate unexpected sql

by Christian Beikov (JIRA)

Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16779 ( https://hibernate.atlassian.net/browse/HHH-16779?atlOrigin=eyJpIjoiNTI4Yz... ) Re: EntityManager.find(Class<T> entityClass, Object primaryKey) generate unexpected sql ( https://hibernate.atlassian.net/browse/HHH-16779?atlOrigin=eyJpIjoiNTI4Yz... ) Why do you believe this is a regression? Just because it is different doesn’t mean it is wrong. Unless you share how the change impacts your app, there is nothing further to discuss. Even though we re-added a special single id lookup SQL statement in 6.3 we might just as well remove that again, unless someone can actually show that this change has any impact.

[JIRA] (HHH-16779) EntityManager.find(Class<T> entityClass, Object primaryKey) generate unexpected sql

by 周雁鸣 (JIRA)

周雁鸣 ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16779 ( https://hibernate.atlassian.net/browse/HHH-16779?atlOrigin=eyJpIjoiNTc3YW... ) Re: EntityManager.find(Class<T> entityClass, Object primaryKey) generate unexpected sql ( https://hibernate.atlassian.net/browse/HHH-16779?atlOrigin=eyJpIjoiNTc3YW... ) I believe it is a regression, it shouldn’t use batch load even if default_batch_fetch_size set or @BatchSize used. It exists in released 6.2.x, but fixed in 6.3.0-SNAPSHOT, I didn’t find related issue so I create this one.

[JIRA] (HHH-16726) Relax readability condition for strict read-write cache items.

by Guenther Demetz (JIRA)

Guenther Demetz ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiMTViZDdlNTIz... ) / Improvement ( https://hibernate.atlassian.net/browse/HHH-16726?atlOrigin=eyJpIjoiMTViZD... ) HHH-16726 ( https://hibernate.atlassian.net/browse/HHH-16726?atlOrigin=eyJpIjoiMTViZD... ) Relax readability condition for strict read-write cache items. ( https://hibernate.atlassian.net/browse/HHH-16726?atlOrigin=eyJpIjoiMTViZD... ) Change By: Guenther Demetz ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Doing some heavy load-tests using Locust we discovered that performance goes down when multiple threads are filling 2ndLevel cache simultaneously with the same persistent objects. Although all threads have more or less the same transaction start timestamp, when it comes to checking the readability of a read-write cache item, the current logic makes following comparison: {noformat}public boolean isReadable(long txTimestamp) { return txTimestamp > timestamp; }{noformat} This implementation considers items unReadable also when the timestamp of current transaction *equals* to the timestamp of the cached item. My proposal is to change the condition to {{ return txTimestamp >= timestamp;}} so that a transaction which started simultaneously with the one that cached the item, can consider valid the puts of other transactions of same age. This has to be modified in : Hibernate 5.6: class org.hibernate.cache.spi.support.AbstractReadWriteAccess.java Hibernate 6: classes org.hibernate.cache.ehcache.internal.strategy.AbstractReadWriteEhcacheAccessStrategy.java & org.hibernate.testing.cache.AbstractReadWriteAccessStrategy.java) By overriding the used region factory the user can choose which granularity he wants for the timestamp comparison, for instance in our use-case we don’t want to go beyond fractions of seconds. {noformat}public class MyJCacheRegionFactory extends JCacheRegionFactory { // UNIT SECONDS public long nextTimestamp() { return System.currentTimeMillis() / 1000; } ... }{noformat} Applying these 2 tweaks on hibernate5.6.15 I was able to enhance the performance in remarkable way: 100 threads accessing fresh (empty 2ndLevelCache) persistence at same time. With {{<property name="hibernate.cache.region.factory_class" value="JCacheRegionFactory"/>}} Threads ran for 14.231 ms with over 247.000 {{isReadable}} calls returning false. {{<property name="hibernate.cache.region.factory_class" value="MyJCacheRegionFactory"/>}} Threads ran for 7.365 ms with 0 {{isReadable}} calls returning false.
