Spring Batch is a lightweight, comprehensive framework aimed at enabling the development of batch applications vital for the daily operations of enterprise systems. Batch applications in this context refers to automated offline systems targeted towards bulk data processing. Spring Batch automates this basic batch iteration, providing the capability to process similar transactions as a set, typically in an offline environment without any user interaction.

Spring Batch works by reading data with a configurable chunk size from a data source, processing it and finally writing it to a resource.
The data source (i.e. process input) and the data sync (i.e. process output) can be flat files (text file, XML file, CSV file...), SQL Databases (MySQL...) or NoSQL databases (MongoDB...).
