All Implemented Interfaces:

PhysicalSlotRequestBulk

public class SharingPhysicalSlotRequestBulk
extends Object
implements PhysicalSlotRequestBulk

Implementation of PhysicalSlotRequestBulk for SlotSharingExecutionSlotAllocator.

The bulk tracks the pending and fulfilled requests by the ExecutionSlotSharingGroup for which the physical slot is being allocated. SlotSharingExecutionSlotAllocator calls markFulfilled(ExecutionSlotSharingGroup, AllocationID) to move a pending request to fulfilled.

Additionally the bulk keeps execution lists for each ExecutionSlotSharingGroup they belong to. If the cancel(Throwable) method is called (due to fulfillability check timeout in PhysicalSlotRequestBulkChecker) then the bulk calls back the SlotSharingExecutionSlotAllocator to cancel all logical slots requests for executions of all bulk's ExecutionSlotSharingGroups.

Constructor Details

SharingPhysicalSlotRequestBulk

public SharingPhysicalSlotRequestBulk(Map<ExecutionSlotSharingGroup,List<ExecutionVertexID>> executions,
 Map<ExecutionSlotSharingGroup,ResourceProfile> pendingRequests,
 BiConsumer<ExecutionVertexID,Throwable> logicalSlotRequestCanceller)

Method Details

getPendingRequests

public Collection<ResourceProfile> getPendingRequests()

Description copied from interface: PhysicalSlotRequestBulk

Returns ResourceProfiles of pending physical slot requests.

If a request is pending, it is not fulfilled and vice versa. PhysicalSlotRequestBulk.getAllocationIdsOfFulfilledRequests() should not return a pending request.

Specified by:

getPendingRequests in interface PhysicalSlotRequestBulk

getAllocationIdsOfFulfilledRequests

public Set<AllocationID> getAllocationIdsOfFulfilledRequests()

Description copied from interface: PhysicalSlotRequestBulk

Returns AllocationIDs of fulfilled physical slot requests.

If a request is fulfilled, it is not pending and vice versa. PhysicalSlotRequestBulk.getPendingRequests() should not return a fulfilled request.

Specified by:

getAllocationIdsOfFulfilledRequests in interface PhysicalSlotRequestBulk

cancel

public void cancel(Throwable cause)

Description copied from interface: PhysicalSlotRequestBulk

Cancels all requests of this bulk.

Canceled bulk is not valid and should not be used afterwards.

Specified by:

cancel in interface PhysicalSlotRequestBulk

markFulfilled

public void markFulfilled(ExecutionSlotSharingGroup group,
 AllocationID allocationId)

Moves a pending request to fulfilled.

Parameters:

group - ExecutionSlotSharingGroup of the pending request

allocationId - AllocationID of the fulfilled request
