3. Wednesda Introduction What is Batch Processing ?
4. Wednesda Introduction “Batch processing is the execution of a series of programs (jobs) on a computer without manual intervention” Wikipedia
5. Wednesda What is Spring Batch ? Introduction
6. Wednesda Introduction
7. Wednesda Introduction Spring Batch is a lightweight, comprehensive batch framework designed to enable the development of robust batch applications vital for the daily operations of enterprise systems. Spring-Batch Doc
8. Wednesda Background SpringSource and Accenture aims to promote the standardization of software processing approaches, frameworks, and tools that can be consistently leveraged by enterprise users when creating batch applications
9. Wednesda Business Scenarios ∙ Commit batch process periodically ∙ Concurrent batch processing: parallel processing of a job ∙ Staged, enterprise message-driven processing ∙ Massively parallel batch processing ∙ Manual or scheduled restart after failure ∙ Sequential processing of dependent steps (with extensions to workflow-driven batches) ∙ Partial processing: skip records (e.g. on rollback) ∙ Whole-batch transaction: for cases with a small batch size or existing stored procedures/scripts
10. Wednesda Technical Objectives ∙ Batch developers use the Spring programming model: concentrate on business logic; let the framework take care of infrastructure. ∙ Clear separation of concerns between the infrastructure, the batch execution environment, and the batch application. ∙ Provide common, core execution services as interfaces that all projects can implement. ∙ Provide simple and default implementations of the core execution interfaces that can be used ‘out of the box’. ∙ Easy to configure, customize, and extend services, by leveraging the spring framework in all layers. ∙ All existing core services should be easy to replace or extend, without any impact to the infrastructure layer.
11. Wednesda Features ∙ Transaction management ∙ Resources Management ∙ Chunk based processing ∙ Parallel Processing ∙ Start/Stop/Restart ∙ Retry/Skip ∙ Logging/Tracing ∙ Job Processing Statistic
12. Wednesda Common Use Cases • Conversion Application • Filtering or Validating Application • Database Extractor • Reporting
