                 URL: https://issues.apache.org/jira/browse/FLINK-17017
             Project: Flink
          Issue Type: Sub-task

    Affects Versions: 1.11.0

The SlotProvider interface should be extended with an bulk slot allocation method which accepts a bulk of slot requests as one of the parameters.

{code:java}
CompletableFuture<Collection<LogicalSlotRequestResult>> allocateSlots(
  Collection<LogicalSlotRequest> slotRequests,
  Time allocationTimeout);
 
class LogicalSlotRequest {
  SlotRequestId slotRequestId;
  ScheduledUnit scheduledUnit;
  SlotProfile slotProfile;
  boolean slotWillBeOccupiedIndefinitely;
}
 
class LogicalSlotRequestResult {
  SlotRequestId slotRequestId;
  LogicalSlot slot;
}
{code}
