The only thing we changed was the version of Hibernate (from 6.1.7 which worked fine to 6.2.0). Also, we denoted a strange behavior of the enhancer, because after enhancement, the entities field became public which is unattended. Our entities are very basic (only private annotated fields an public getters/setters), there are only some inheritance of generic fields: @Entity @Table(name = "mytable" ) public class MyTable extends AbstractSimpleTable<MyTablePK> { private static final long serialVersionUID = 1L; @EmbeddedId private MyTablePK mytablePK; @Column(name = "COLUMN1" ) private String column1; @Column(name = "COLUMN2" ) private String column2; public MyTablePK getMytablePK() { return sysusrPK; } public void setMytablePK(MyTablePK mytablePK) { this.mytablePK = mytablePK; } public String getColumn1() { return column1; } public void setColumn1( String column1) { this.column1 = column1; } public String getColumn2() { return column2; } public void setColumn2( String column2) { this.column2 = column2; } } And the superclass: @MappedSuperclass public abstract class AbstractSimpleTable<P extends Shareable> { @Lob @Column(name = "GENERICFIELD" ) private String genericfield; public String getGenericfield() { return genericfield; } public void setGenericfield( String genericfield) { this.genericfield = genericfield; } } Thanks for the help !

[JIRA] (HHH-16410) SingleIdEntityLoader repeatedly translates SQL AST

by Christian Beikov (JIRA)

Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiMGFjMjI1MjQw... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16410?atlOrigin=eyJpIjoiMGFjMj... ) HHH-16410 ( https://hibernate.atlassian.net/browse/HHH-16410?atlOrigin=eyJpIjoiMGFjMj... ) SingleIdEntityLoader repeatedly translates SQL AST ( https://hibernate.atlassian.net/browse/HHH-16410?atlOrigin=eyJpIjoiMGFjMj... ) Change By: Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) For byId lookups, it looks like {{org.hibernate.loader.ast.internal.SingleIdEntityLoaderDynamicBatch#load}} is called, and that causes SQL translation over and over again, though it should be cached. It is also looks fishy to me that we do not try to cache SQL statements for a certain batch size, though that isn’t important for now. In a throughput test, this was identified as causing perf issues compared to 5.
