(I post my questions as new Topic as most of the other topics which similar questions have been “solved”)
So, first question is whether the lock by the task client is per topic or per activity instance. I guess the latter?
I’m asking because I want to use the same topic name in many tasks within the same process model (and even in different process models):
So, would this make sense/work?
Actually, I’m thinking to wrap one external task with the one topic around a Call activity and use this Call activity in many places in a process:
Will I have any issues?
I have a process which has many tasks to be performed by a (physical) robot. I don’t want for each of this tasks to have different topics (e.g. based on the name of the task). I’d like to have one topic (e.g. RobotTask) and based on the name of the task and the variables, the task client will inform the robot accordingly.
Also, in this example here Spring Boot Starter for the External Task Client | Camunda
the call to a service (e.g. DB query) and the task completion is done within the same class. But how is the asynchronous pattern achieved?
In my case, what should be the business logic of the task client/worker?
I see it as two steps:
- Send the info to the robot.
- (Robot does its job and after X minutes informs the task client. Actually I want also the task client to subscribe to a service which catches changes on the task)
- Task client completes the task (if the notification from the subscribed service says that the “task_status= completed”)
I thought that these are separate and couldn’t be in the same class. What do I miss?
Should I split the internal pattern of the call activity into two external tasks/topics? (One to send the task info and one to catch the updates and completes?)
Thank you
