Current Activiti Engine does not support Multiple ServiceTask concurrency orchestration, can not use Activiti in some scenario

I am implementing a scenario that is all the tasks are ServiceTask.For example, we are going to upgrading a group of servers, there are three types of servers, nginx, web and database servers, we find activiti's workflow engine can help with it, such as when upgrade servers, we need to control first

BTW, I can find the Camel recommedation @ below link, but as our scenario is we will generate BPMN model dynamicly, but we can not generate the AsyncCamelRoute dynamicly, so this does not work for our scenario, hope Acitivti does support such general workflow orchestration

public class AsyncCamelRoute extends RouteBuilder {

@Override
public void configure() throws Exception {

    from("activiti:asyncCamelProcess:serviceTaskAsync1").setHeader("destination", constant("activiti:asyncCamelProcess:receive1")).to("seda:asyncQueue");
    from("seda:asyncQueue").to("bean:sleepBean?method=sleep").to("seda:receiveQueue");

    from("activiti:asyncCamelProcess:serviceTaskAsync2").setHeader("destination", constant("activiti:asyncCamelProcess:receive2")).to("seda:asyncQueue2");
    from("seda:asyncQueue2").to("bean:sleepBean?method=sleep").to("seda:receiveQueue");

    from("seda:receiveQueue").recipientList(header("destination"));
}
}

Lots of people have similar requirements, hope Activiti Team can help us, Activiti is very good, we can not give it up just by some missing features, thanks very much!

Make all your tasks async.
The problem with the join has been currently fixed on master (will be part of 5.16 release).
It's a matter of setting activiti:async="true" on the joining parallel gateway and no need for camel anymore.

As far I can see the requirement, you can fully use asynch service task. There is no need to use camel for this purpose.
Even if you need to use camel, you do not need to generate routes. A fixed static route seems to be suitable.
