Child Workflows

Infinitic is still in active development. Subscribe here to follow the progress.

Infinitic lets us use child workflows like tasks. The newWorkflow function behaves as the newTask function but dispatches a (sub)workflow, instead of a task. When the (sub)workflow completes, the return value is sent back to the parent workflow.

The illustration below illustrates this, with a workflow of 3 sequential tasks:

For example, a distributed (and inefficient) way to calculate n! is shown below, using n workflows, each of them - excepted the last one - dispatching a child-workflow.

public class Calculate extends Workflow implements CalculateInterface {
    private final Calculate calculate = newWorkflow(CalculateInterface.class);

    public Long factorial(Long n) {
        if (n > 1) {
          return n * calculate.factorial(n - 1);
        return 1;
class Calculate() : Workflow(), CalculateInterface {
    private val calculate = workflow<CalculateInterface>()

    override fun factorial(n: Long) = when {
        n > 1 -> n * workflow.factorial(n - 1)
        else -> 1
