I worked a few years on a project which used Spring Batch for batch processing jobs. Here I would like to give you a brief, beginner friendly introduction to this technology.

Spring Batch is a framework designed for building robust, scalable batch processing systems in Java. It simplifies the creation of batch jobs, which involve processing large volumes of data, such as database records, files, or transactional data. Batch jobs typically run without user interaction, often as scheduled tasks, making them suitable for transaction processing, data import, data migration, reporting, or billing systems.

Spring Batch divides a job into steps, where each step performs specific tasks like reading data, processing it, and writing the output. It supports features like transaction management, retry and skip logic, and chunk-based processing, where large datasets are processed in manageable chunks to avoid memory issues.

The framework integrates with other Spring modules, providing flexibility in job configuration and execution. Its declarative XML or Java-based configuration allows for easier maintenance and readability.
