[Feature Request] Await multiple signals in a workflow

[Jacek Rz]

Is your feature request related to a problem? Please describe.

Following this, we are trying to implement a wait for multiple signals in a Temporal Workflow. It seems that the JVM SDK has Workflow.await suited exactly for this purpose, is there a similar tool in Typescript?

Describe the solution you'd like

Expressing our workflow e.g. like this:

Workflow.wait(() -> allSignalsReceived());

Additional context

So far we have managed to implement this as a while loop:

while(true) {
  if(allSignalsReceived()) {
    break;
  }
  await workflow.sleep(1000);
}

The above implementation is causing OutOfMemory issues for the workers, we understand this is because every iteration of the unbounded loop is getting cached. We understand we might be able to resolve the memory issues with workflow.continueAsNew or by drastically reducing the maxCachedWorkflows param, but neither of these options seem like a production-grade solution.

Closing - turns out there is workflow.condition for this exact purpose already!
