Hello, I was looking at the https://github.com/temporalio/hello-world-project-template-java example and also at the documentation in general, and I have some basic questions: From the example: One of them starts a workflow synchronously ( InitiateHelloWorld ) and executes a method, a workflow th…

how do I actually signal the worker to start the workflow? To me, once I execute the worker code, that doesn’t seem to do anything in terms of execution, just set up, and association of worker with workflow. Would you first create a worker listening to a task queue, and then start the workflow eit…

i would like my workers to startup during service init … and i have the following snippet func initWorkers() { // Create the client object just once per process c, err := client.NewClient(client.Options{}) if err != nil { log.Fatalln("unable to create Temporal client", err) } // This worker …

I think in your case, the worker is not listening on a task queue as there are no activities and workflow types are registered with it. Use w.RegisterWorkflow and w.RegisterActivity to associate your activity and workflow implementations with the worker. Yes, the list of the connected workers shoul…

hi maxim, thanks , so i guess whenever i start a worker i have to register workers and activities beforehand… i was thinking that i could have workers just on standby listening on their respective task queues and dynamically submit workflows, activites on the queue kam

Would you explain the use case? Are you planning implementing activities and workflows dynamically?

Our microservices uses NATS and I was just thinking I will could one microservices as a broker to termporal , this service will be subscribing to: - Start worker / Stop work etc Register workflow Register activity start workflow / activity So i guess i don’t get much benefit out of that … mi…

thanks for the link clears things up for me … cheers

Hi Maxim, In case of dynamic queries, once we register a DynamicQueryListener, is the data returned from this method visible through the Temporal Web UI ? ( i.e in the Workflow Detail View page / Queries Tab ) . How can we surface it on the Web UI ?

I don’t think it is currently visible. We could add the ability to the UI to specify query type explicitly. But the user would need to know the query name. For some cases, the DynamicQueryHandler could return the names of queries it supports. Please file issues for this.

In this answer I give my opinion why implementing activities and workflows directly is preferrable.
