In this tutorial series, you are going to learn, how to achieve batch processing via Spring Batch API.

 

Following are some of use cases that you will achieve via Spring Batch.

a.   Perform ETL (Extract, Transform, and Load) tasks.

b.   Reporting: For example reporting user bank statement every month, report mobile post-paid bills etc.,

c.    To Perform Data Migration Tasks. Spring Batch provide features like rollback and commit counts to make these data migration tasks easy.

a.   Load a file content
