If you have a batch processing records in chunks you probably want to keep track of what succeeds and fails. The issue is the commit is often done after your business code is executed which means you kind of loose track of what happens.
To solve it you can use TransactionSynchronizationRegistry and Synchronizations.
Java 8 streams are very expressive – even if RxJava is even more 😉 – but sometimes EE integration is not that advanced. In case of a batch import of data it would be handy to use Stream API since we iterate over data to persist them but how to ensure we can use chunking – ie get a commit interval to not commit for each record?
