Which areas of Spring Batch would you like to improve the most?

[fmbenhassine]

Some areas to consider are for example performance, batch infrastructure configuration, documentation, samples, etc.

If needed, please add a comment to specify the details on what to improve.

Personally I find the listeners a bit hard to work with. There are some black magic behind the listener(Object listener) listener registrations. Also not always clear which listener is part of the transaction boundary and which one is not. Although, I might need to spend more time on the documentation. Still, when we needed to combine with fault tolerance, some careful debugging was needed until we could finalize our batch design for edge cases as well.

Thank you for your feedback! I agree, that part of the framework is a bit confusing. We need to improve the listener registration process (see #4808 and #4633) and improve the documentation regarding transaction boundaries.

It would be very valuable to allow processor to handle chunks of items, instead of processing each element one by one

From my experience, more real-world examples and practical guides would make Spring Batch easier to learn and use, especially for advanced features.

So I'll go with the Documentation/Samples were spring boot need to improve more.
