Spring Batch is an open source, lightweight, and comprehensive solution designed to enable the development of robust batch applications that are vital for enterprise operations.

Packed with real-world examples, this book starts with an insight into the batch applications and Spring Batch offerings. After exploring the architecture and key components, you will learn how to develop and execute a batch application. While gaining insights on the essential configurations and execution techniques for batch jobs, you will learn about the key technical implementations of the read, write, and processing features for different forms of data. Next, you will move on to the key features such as transaction management, job flows, job monitoring, and data sharing across the steps of the executing jobs. Finally, you will learn how Spring Batch can integrate with diverse enterprise technologies and facilitate optimization and performance improvement with scaling and partitioning techniques.
