Spring Batch Framework covered in 4 levels of difficulty: beginner, intermediate, advanced and expert, with source code

This Spring Batch Mastery Course is split into 4 chapters by depth / difficulty: beginner level, intermediate, advanced and expert. During each chapter, Spring Batch application with source code is available which you are able to run locally. So, in total it's 4 different applications.

Beginner level chapter is for those who are new to Spring Batch, with little to no prior experience. The most essential framework concepts are introduced, like jobs, steps, readers, processors and writers. We will cover tools for data processing with files: plain text format and XML. Spring Batch command line application analyzing temperature sensors data will be built and executed.

Intermediate level chapter comprehensively covers concept of chunk-oriented processing. Foundational entities, including JobInstance, JobExecution, StepExecution and ExecutionContext, are introduced. Restartability concept and related ExecutionContext re-use is covered in depth for success and failure scenarios, and various settings usage, e.g. saveState, allowStartIfComplete, preventRestart, etc. Various tools, approaches and design patterns to work with relational databases are covered, as well as tools to read and write JSON format. Command line application with conditional step execution and end-to-end test coverage sums up the chapter.

Designed for individuals with a strong grasp of Spring Batch in typical scenarios, the advanced level chapter delves deeper into the framework's sophisticated features and functionalities. It covers multi-file and multi-line plain text format scenarios that require custom reader implementation, as well as @StepScope component to access JobParameters and ExecutionContext declaratively. The application is web-based through Spring Boot integration, and started via HTTP endpoints. Retries, skips and split parallel step executions are explained clearly.

Lastly, the expert level is designed for those proficient in the majority of Spring Batch features, focusing on strategies to scale batch workloads effectively. The designed web-based application will solve the same business problem in 4 different ways: with single thread, with multiple threads, partitioned locally, and with distributed partitioning. The chapter has lots of visual technical design episodes which covers both architecture and code level nuances of the scalability tools provided by the framework.
