Spring in Finance eXchange 2008: David Syer on Realising the power of Spring Batch
Realising the power of Spring Batch
Spring Batch is a framework for application developers to help them produce offline and batch processes that are efficient, easy to configure and manage. It also provides some important quality of service features that are particularly relevant in mission critical situations in finance. Dave will provide a quick introduction to Spring Batch for novices, showing the benefits of using a framework for offline and batch processing, with reference to some examples of use cases in financial institutions. Then there will be a tour of the key themes in Spring Batch 2.0, including simplifications of some of the core APIs and the features we are providing to support scalability. To keep it all real there will be a demonstration of some of the features discussed.
Review:
In this talk, Dr. David Syer discusses Spring Batch on a general scale. After giving a brief overview of the framework, API changes and some new features planned for the 2.0 version, he dives into an explanation of processing and scalability patterns. Dave provides live demos showing various properties of the framework.
Dr. Syer shows that some business logic can be explained through a series of abstractions. JobLauncher, JobExecutionListener interfaces are used for this purpose. Requirements for assuring a high quality of service for batch processes are explained.
One demonstration utilizes the ItemReader and ItemProcessor interfaces. An annotation-driven programming model, which will be an important property of the new version of Spring Batch is then introduced and sequential execution and parallel execution models are explained. Dave concludes the talk with an overview of chunk-oriented programming.
In conclusion, Dave shows that Spring Batch is a reliable way of developing robust batch applications that are crucial in the daily operations of enterprise systems. It's reusable functions, advanced services, and many features enable extremely high-volume and high performance batch jobs though optimization and partitioning techniques.
