What is Spring Batch, and what kind of problem is it designed to solve?

Spring Batch

Spring Batch is a framework for building robust, high-volume batch processing applications — jobs that read, process, and write large quantities of data on a schedule or on demand, like a nightly file import, a data migration, or a report generation run. It provides reusable building blocks for exactly the concerns that are painful to hand-roll correctly: chunked processing, transaction management around batches of records, skip/retry logic for bad records, and the ability to restart a failed job from where it left off rather than from scratch.
