Is there a centralized way in Temporal to notify all workers running on different JVM to suspend polling?

[William_Lam]

Thanks @tihomir , some follow up questions,

@maxim

Workflows should not ever be tied to specific workers.

Is it because a workflow can get picked up by a worker running in a different process/pod?

@maxim

You can have an activity listening on a worker-specific task queue. Then use that activity to act on other workers in the same process

1. how would this activity find the workers?
2. If I have 2 processes running, how would I ensure this activity will be run on both processes?

@maxim

So a host when coming up would require registration through a signal to this notification workflow or getting identities of the workers from DescribeTaskQueue request and constructing queue name from identity for each worker.

I couldn’t find reference in Java API doc for DescribeTaskQueue and am confused about the registration part.

Appreciate any help on this topic.
