parallel processing in Activiti flow

pisadr

We have a flow designed in Activiti.
Start -> A -> B -> C -> End

I have a thread pool executor that gets the request from queue and submits the task to Activiti flow.
Can I design Activiti flow to process multiple requests submitted by multiple threads? (parallel execution of multiple requests)
OR is it always that I need to wait to complete one request and then the Activiti will process second request?

Thanks

Hi,

You can use the async="true" attribute to let the engine process request asynchronously.

Hi trademak,
Thanks for the reply.
I am using "SpringProcessEngineConfiguration" to initialize/start the Activiti engine.

This is what I have in my spring based config -
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
    <property name="dataSource" ref="dataSource" />
    <property name="transactionManager" ref="transactionManager" />
    <property name="jobExecutorActivate" value="true" />
</bean>

Where do I need to mention "async="true" to start the processing in parallel.

Hi,

If you use Activiti Designer, you can specify that in the properties view of each service task.

Otherwise configure it directly in the xml as described here http://www.activiti.org/userguide/index.html#asyncContinuations in the userguide.
