PhysicalSlotRequestBulkChecker (Flink : Runtime 2.0-preview1 API)

All Known Implementing Classes:

PhysicalSlotRequestBulkCheckerImpl
```
public interface PhysicalSlotRequestBulkChecker
```
This class tracks a fulfillability timeout of a bulk of physical slot requests.
The check stops when all pending physical slot requests of PhysicalSlotRequestBulk are fulfilled by available or newly allocated slots. The bulk is fulfillable if all its physical slot requests can be fulfilled either by available or newly allocated slots or slots which currently used by other job subtasks. The bulk gets canceled if the timeout occurs and the bulk is not fulfillable. The timeout timer is not running while the bulk is fulfillable but not fulfilled yet.

    Parameters:
    
    mainThreadExecutor - the main thread executor of the job master
  - schedulePendingRequestBulkTimeoutCheck
```
void schedulePendingRequestBulkTimeoutCheck(PhysicalSlotRequestBulk bulk,
                                            Duration timeout)
```
    Starts tracking the fulfillability of a PhysicalSlotRequestBulk with timeout.
    
    Parameters:
    
    bulk - PhysicalSlotRequestBulk to track
    
    timeout - timeout after which the bulk should be canceled if it is still not fulfillable.
