BATCH PROCESSING IN ACTION HILLMER CHONA RODRIGO GRACIANO
WHAT SPRING BATCH IS? 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. https://docs.spring.io/spring-batch/docs/current/reference/html/index-single.html#spring-batch-intro
WHAT SPRING BATCH IS NOT? Spring Batch is not a
scheduler https://docs.spring.io/spring-batch/docs/current/reference/html/index-single.html#spring-batch-intro

BATCH ARCHITECTURE (SIMPLIFIED ) https://docs.spring.io/spring-batch/docs/current/reference/html/images/spring-batch-reference-model.png JobRepository JobLauncher Job Step Reader
Writer 1 * 1 1 1 1
JOB REPOSITORY •It’s how Job, Step, JobParameters, JobExecution, and StepExecution
are persisted
• JobRepository • JobLauncher • JobRegistry • JobExplorer • PlatformTransactionManager
• JobBuilderFactory • StepBuilderFactory @EnableBatchProcessing
RUNNING JOBS • From the command Line (CommandLineJobRunner) • Within
a web container

SCALING AND PARALLEL PROCESSING • Multi-threaded (Async Executor) • Parallel
steps (Split) • Remote Chunking (Data processed by slaves – Real data sent not a reference) • Remote Partitioning (Data in chunks and local to slaves)
