Spring Batch

In the course Spring Batch from SpiralTrain participants learn to use the open source Framework Spring Batch for batch applications that require the processing of large amounts of data without human i

Spring Batch Intro

The course starts with an overview of the architecture of the Spring Batch Framework and the essentials of Spring and Spring Boot. The parts of Spring Batch are explained here, such as Jobs, Steps, ItemReaders, ItemProcessors and ItemWriters.

Job Configuration

Next the configuration of Jobs and the role of Job Parameters are discussed. Job Listeners, the Execution Context and persistence are also addressed.

Step Processing

Spring Batch typically uses a Chunk-oriented processing style where steps in a transaction are first read in, then processed and finally written. In the course this step processing is extensively treated including chunk size configuration and step listeners.

Job Repositories

The role of Job Repositories with an in memory representation or by using databases and JobExplorers and JobLaunchers are also on the course schedule.

Scalability

Finally after going into the details of ItemReaders, ItemProcessors and ItemWriters, attention is paid to tuning and making the batch processing scalable by using parallelization, multiple threads and asynchronous calls.

Audience Course Spring Batch

The course Spring Batch is intended for experienced Java Developers who want to use Spring Batch to process large amounts of data.

Prerequisites Course Spring Batch

Experience with Java programming and object orientation is required to participate in this course. Prior knowledge of the Spring Framework is beneficial to good understanding.
