split-flow processes executed as asyncTaskExecutor doesn't work a throttle-limit?

[bumzpark]

on my project, when i tried several flows in <split/>, found parraller processing do not work through throttle-limit.
it looks like whole processes(flows) are working concurrently in a batch log.

i am trying to execute 10 more flows in a split, but if whole flows are working concurrently,
it could cause a db-connection pool issues.

So is there anyway to adopt a throttle-limit in a split-flow asyncTaskExecutor?

<split id="split01" task-executor="asyncTaskExecutor">
	<flow>
		<step id="STEP30" parent="flowControlStep">
			<tasklet ref="TSKLET01"/>
		</step>
	</flow>
	<flow>
		<step id="STEP31" parent="flowControlStep">
			<tasklet ref="TSKLET02"/>
		</step>
	</flow>
	<flow>....
</split>

What version of Spring batch?
Can I assume your attempting to throttle a SimpleAsyncTaskExecutor?
If so, can you confirm that the Throttle is active? Maybe log out isThrottleActive() just to confirm the throttle is being applied.

my project is using spring-batch-core-2.1.5.RELEASE.jar, org.springframework.core-3.0.2.RELEASE.jar.
also asyncTaskExecutor is defined as
<bean id="asyncTaskExecutor" class="org.springframework.core.task.SimpleAsyncTa skExecutor">

So I added property to my job.xml as below

<bean id="asyncTaskExecutorSplit" class="org.springframework.core.task.SimpleAsyncTa skExecutor">
<property name="concurrencyLimit" value="4"/>
<property name="threadNamePrefix" value="AsyncThread-"/>
<property name="daemon" value="true"/>
</bean>

it works fine now,
thanx visualjeff for reminding...
