Commit interval [BATCH-2534]

[spring-projects-issues]

sunny bindal opened BATCH-2534 and commented

according to the logic commit interval work as these:-
List items = new Arraylist();
for(int i = 0; i < commitInterval; i++){
Object item = itemReader.read()
Object processedItem = itemProcessor.process(item);
items.add(processedItem);
}
itemWriter.write(items);

BUt in actually it is not as specified in "org.springframework.batch.core.step.item.ChunkOrientedTasklet.execute(StepContribution, ChunkContext)" it first read to the full commit interval then process and then calls write. It is :-

List items = new Arraylist();
for(int i = 0; i < commitInterval; i++){
Object item = itemReader.read()
items.add(processedItem);
}for(int i = 0; i < commitInterval; i++){
Object processedItem = itemProcessor.process(item);
}
itemWriter.write(items);

Please look into this.
