Spring Batch is a framework for batch processing in Java. It allows developers to process large volumes of records by dividing the work into small chunks called steps. The framework includes components like job launcher, job repository, step, item reader, item processor and item writer to process a batch job. Jobs are composed of steps, and steps use readers, processors and writers to read, process and write data.
