Loop Step with partitioning

[srinivas_vsk]

Hello

My use case is somewhat like this. We need to process 10 different items using the same step. Each time the step is executed, we need to partition say 2 items so they can run parallelly. Once 2 partitions are completed the step should repeat itself to process the next 2 items.

<step id="loopStep" next="loopDecision">
			<partition step="batchValidate" partitioner="partitioner">
				<handler  task-executor="taskExecutor"/>
			</partition>
		</step>

1) But what im noticising is, the second run of loopStep , the partition happens but it is not executing batchValidate again?

2) Also i need to repeat the loopStep only when the individual partitions have executed.

Please let me know if you need more code or what am i doing wrong?

Thanks
Srinivas

1) You might need to add allow-start-if-complete="true" to batchValidate. Although I think if you use the latest versions of Spring Batch they try to detect a duplicate step name in the same JobExecution and allow it to start unconditionally, so you might not need to.
2) Should work fine. Is there a problem?

1. Yes i tried that and worked fine but not if i have flow inside the batchvalidate. i have posted another question on this
2. IT looks like the loop is repeated only after partitions have completed. but not sure how to validate it?

Thanks for looking
