public final class Awakeable<T> extends Awaitable<T>
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 id(), and then let another service consume from Kafka the responses of given external system interaction by using Context.awakeableHandle(String).

NOTE: This interface MUST NOT be accessed concurrently since it can lead to different orderings of user actions, corrupting the execution of the invocation.
