More than one trigger (subjob dependencies)?

Anonymous — Wed, 10 Feb 2016 05:43:57 GMT

Hello,

is it possible to run a Subjob only if two more Jobs ran sucessfully (more than one Job dependency).
Something like that
Subjob D waits for finishing Subjob A and B
Subjob E waits for Subjob A and C
Subjob F has to wait for D and E
...
Is it possible to run a Subjob if at least one Job has finished:
Subjob C waits until Subjob A OR Subjob B has finished

Thanks

Hi Olbu,
A ---onSubJobOk--- C
|
Runif
|
B

Here , In subJob B , try to set globalMap variable and In Runif ,try to get value and check it is not null.
Note that You cannot have 2 onSubJobOk link on 1 Component. So you have to eliminate this limitation by using Runif link in second subjob.

I hope, it will help you.

Amol

Hi Amol,
thanks, but I think that this couldn't work. C depends on a successful run of A and B. In your case Talend DI starts C also if only A would be ready.
But, yes. We could implement this with few "run if"-trigger. Today we would define a tPrejob wich defines a global variable (tSetGlobalVar)
Name:

"myTriggerCount"

Value:

new java.util.concurrent.atomic.AtomicInteger(0)

The last component of our A and B would have the following "run if"-trigger condition:

((java.util.concurrent.atomic.AtomicInteger) globalMap.get("myTriggerCount")).incrementAndGet()==2

, but we hoped that there would be some stages which support such scenarios by default. (Perhaps we also need to check the Status of the last component of A and B)
Thanks
