Spring data batch saveAll handling exceptions

Question

I have a Spring boot application where I am doing a lot of inserts by collecting data from kafka. I wish to use saveAll batch insert for increasing performance. But there are few datas that would be considered duplicates and I am updating them whenever catching DataIntegrityViolationException in my code. With batch insert, is there a way to catch this exception for each data that is duplicate and handle that with the do update code?

You could use the @SQLInsert annotation of Hibernate to change the way the inserts are done. See Hibernate Transactions and Concurrency Using attachDirty (saveOrUpdate) for details.
