CTE Bulk Id Strategy for Hibernate

Bulk Id Strategy implementation for Hibernate using CTE instead of Temporary Table, reducing concurrency on system tables every time Postgresql creates temp tables.

Generated sql example

WITH ht_person ( doc_number ) as ( values (?), (?), (?), (?) ) UPDATE public.person SET name = 'Evandro', birth = '1987-11-26' WHERE ( doc_number ) IN ( SELECT doc_number FROM ht_person ); 

How to use

It is very simple.

Make the jar using

mvn package

Just add the JAR in your classpath and add the line below in your hibernate.cfg.xml

<property name="hibernate.hql.bulk_id_strategy">br.com.evandropires.hibernate.ctestrategy.CTEMultiTableBulkIdStrategy</property>
