1. case class BlockingSubmitJobResponse(matchId: MatchId, jobId: JobId, matchEpochUTC: Long, workerCoords: List[WorkerRedirectCoords], workers: List[WorkerDetails]) extends ClientResponse with Product with Serializable

   

2. sealed trait ClientRequest extends AnyRef

   

   A 'client' represents something which submits work to the exchange

3. sealed trait ClientResponse extends AnyRef

   

4. trait Exchange extends JobPublisher

   

   An exchange supports both 'client' requests (e.g.

   An exchange supports both 'client' requests (e.g. offering and cancelling work to be done) and work subscriptions

5. trait InputDao[T] extends AnyRef

   

6. trait JobPredicate extends AnyRef

   

   Exposes the course-grained signature of pairing up jobs with worker subscriptions

7. trait JobPublisher extends AnyRef

   

8. case class ListSubscriptions(subscriptionCriteria: JMatcher) extends ObserverRequest with Product with Serializable

   

9. case class ListSubscriptionsResponse(subscriptions: List[PendingSubscription]) extends ObserverResponse with Product with Serializable

   

10. trait MatchObserver extends OnMatch with StrictLogging

    

    Represents a match 'handler' which delegates out to other observers

11. sealed trait ObserverRequest extends AnyRef

    

12. sealed trait ObserverResponse extends AnyRef

    

13. case class PendingSubscription(key: worker.SubscriptionKey, subscription: WorkSubscription, requested: Int) extends Product with Serializable

    

14. trait QueueObserver extends AnyRef

    

    Represents something which can check the current state of the exchange queues.

    Represents something which can check the current state of the exchange queues.

    This is current kept separate from the Exchange signature so as (1) to require/expose less about a particular exchange itself (2) more practically, expose potentially separate APIs in cases such as e.g. our ui

15. case class QueuedJobs(subscriptionMatcher: JMatcher, jobMatcher: JMatcher) extends ObserverRequest with Product with Serializable

    

16. case class QueuedJobsResponse(jobs: List[SubmitJob]) extends ObserverResponse with Product with Serializable

    

17. case class RequestWork(id: worker.SubscriptionKey, itemsRequested: Int) extends SubscriptionRequest with Product with Serializable

    

18. case class RequestWorkAck(id: worker.SubscriptionKey, totalItemsPending: Int) extends SubscriptionResponse with Product with Serializable

    

19. case class SelectIntMax(path: JPath) extends SelectionMode with Product with Serializable

    

20. case class SelectN(n: Int, fanOut: Boolean) extends SelectionMode with Product with Serializable

    

21. case class SelectionAll() extends SelectionMode with Product with Serializable

    

22. case class SelectionFirst() extends SelectionMode with Product with Serializable

    

23. abstract class SelectionMode extends AnyRef

    

24. case class SubmissionDetails(aboutMe: Json, selection: SelectionMode, workMatcher: JMatcher, awaitMatch: Boolean) extends JsonAppendable with Product with Serializable

    

    Contains instructions/information specific to the job scheduling/matching

25. case class SubmitJob(submissionDetails: SubmissionDetails, job: Json) extends ClientRequest with Product with Serializable

    

    Represents anything which can be run as a job

    Represents anything which can be run as a job

    Json is a bit prescriptive, but that's going to cover 95% of the cases. Even if we have binary data, we can base64 encode it as an option.

    If we end up doing a lot of data transfer, then we can change the job representation to be an akka Source

    job

    represents the job submission. As the job repo is heterogeneous, it could match anything really that's asking for work

26. case class SubmitJobResponse(id: JobId) extends ClientResponse with Product with Serializable

    

27. sealed trait SubscriptionRequest extends AnyRef

    

28. sealed trait SubscriptionResponse extends AnyRef

    

29. case class WorkSubscription(details: WorkerDetails = WorkerDetails(), jobMatcher: JMatcher = JMatcher.matchAll, submissionMatcher: JMatcher = JMatcher.matchAll) extends SubscriptionRequest with Product with Serializable

    

    The details contain info about the worker subscribing to work, such as it's location (where work should be sent to), and any arbitrary json data it wants to expose (nr of CPUs, runAs user, available memory, OS, a 'topic', etc)

    The details contain info about the worker subscribing to work, such as it's location (where work should be sent to), and any arbitrary json data it wants to expose (nr of CPUs, runAs user, available memory, OS, a 'topic', etc)

    Once a WorkSubscription is sent

    jobMatcher

    the json matcher used against the 'job' portion of SubmitJob

    submissionMatcher

    the json matcher used against the additional 'details' part of SubmitJob
