Awakeable

An Awakeable is a special type of Awaitable which can be arbitrarily completed by another service, by addressing it with its id.

It can be used to let a service wait on a specific condition/result, which is fulfilled by another service or by an external system at a later point in time.

For example, you can send a Kafka record including the Awakeable.id, and then let another service consume from Kafka the responses of given external system interaction by using RestateContext.awakeableHandle.
