Batch processing of data is an efficient way of processing large volumes of data where data is collected, processed and then batch results are produced. Batch processing can be applied in many use cases. One common use case of batch processing is transforming a large set of flat, CSV or JSON files into a structured format that is ready for further processing. Spring Batch provides functions for processing large volumes of data in batch jobs.
