After migration from 4.2.x to 5.2.9 batching susbsystem( @ ~ vladmihalcea) stops working we got
{noformat}
08:46:59,871 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-53) ERROR: duplicate key value violates unique constraint "pk_purchase_document"
Details: Key (id_purchase_document)=(266985) already exists.
{noformat}
Test case
https://github.com/MirekSz/hibernate-HHH-11634
In screenshots you can see what is wrong. In action queue there are 3 elements with the same id (hash = 5167) which generates after all inserting 3 times elements with the same id (with hibernate.order_inserts false it works)
Config:
hibernate.order_inserts true
hibernate.jdbc.batch_size 10
I also try SNAPSHOT VER after HHH-11585 but the same error occurs |
