I have a use case where I am using temporal to replace an existing ingest process. There is a requirement where requests that come through for the same ingest id, must be run in the order that they arrive. To implement this I have used the suggestion outlined by maxim here: design patterns - Job q…

Thanks maxim - this is exactly what I was looking for. I’ll try it out.

Hi Maxim, In the java version if my child workflow had a method called execute() that had to be called to trigger the actual workflow how would that be done in the code below? Also is there any option to do something similar to the BatchRequest where you could pass multiple methods in to be trigge…

Good catch. The workflow has to be started before waiting for a child to start. MyChildWorkflow child = Workflow.newChildWorkflowStub(MyChildWorkflow.class, options); Async.procedure(child::execute); Promise<WorkflowExecution> childExecution = Workflow.getWorkflowExecution(chil…

Hi Maxim, I’m not able to trigger the child workflows asynchronously with the above code. I tested the workflow synchronously and it works but asynchronously my execute() method is never getting called. Would there be another step I’m missing to trigger the workflows?

Could you post the workflow execution history for the parent?

Here is the history: [Temporal Child Workflow History] I noticed that in step 6 the parentClosePolicy is PARENT_CLOSE_POLICY_TERMINATE. Could this be the issue?

The forum post I referenced had correct text description, but invalid sample code. Make sure that you set ParentClosePolicy to ABANDON. Not the cancellation type: ChildWorkflowOptions options = ChildWorkflowOptions.newBuilder() .setParentClosePolicy(ParentClosePolicy.…

Thanks Maxim, I have applied the update but the workflow still does not trigger. [Temporal Child Workflow History II] My code snippet for triggering the workflow: System.out.println(String.format("workflow execute START ASYNC")); Async.procedure(workflow::execute); System.out.println(String.…

Something is weird. How is your workflow completing if the workflow method is blocked on childExecution.get()? Are you using multiple threads?
