----------------------------------
I am now working on this issue. This is the implementation plan.
1. It will contain ExecutionSlotAllocator, DefaultExecutionSlotAllocator,
ExecutionVertexSchedulingRequirements, SlotExecutionVertexAssignment and unit
tests for DefaultExecutionSlotAllocator.
2. The DefaultExecutionSlotAllocator will use a SlotProvider to allocate slots
and then return the SlotExecutionVertexAssignment to the caller. It will
contain a Map<ExecutionVertexID, SlotExecutionVertexAssignment> to cache the
unfulfilled slot requests.
There is one problem:
1. The SlotProvider needs ScheduledUnit when allocating slots, but I think
ExecutionSlotAllocator should get rid of Execution and ScheduleUnit, so It may
need to create a new class extending the ScheduleUnit and use it in the
ExecutionSlotAllocator.
[~gjy], do you have any suggestion?
