Zeebe- Dynamically determine the tasks to be executed in a workflow

Workflow Execution
#1

Hi Zeebe Community,

In a workflow, I would like to execute a step ‘n’ times based on the response returned by the previous step.

Let’s assume my workflow has 2 tasks.

Start → Task1 → Task 2 → End

‘Task1’ is handled by a worker and returns a payload containing list of ‘n’ objects.

After Task1 completes, I would like to execute ‘n’ number of tasks of type ‘Task2’ (sequentially or concurrebt). Is it possible to model this behavior in Zeebe?

Hi @Ajay,

first, welcome to the community :tada:

After Task1 completes, I would like to execute ‘n’ number of tasks of type ‘Task2’ (sequentially or concurrebt). Is it possible to model this behavior in Zeebe?

Yes! I see two options:

  • model a loop around the task (i.e. exclusive gateway using a loop counter)
  • mark the task as multi-instance, sequential or parallel (i.e. the input collection defines the iterations)

Does this help you?
How many iterations do you expect?

Best regards,
Philipp

Hi Philipp,

Thank you for your quick response!

The second option helps me. I am trying to implement the second option(using multi-instance). I will let you know if i come across any issues.
