public class AllocationID
extends org.apache.flink.util.AbstractID

Unique identifier for a physical slot allocated by a JobManager via the ResourceManager from a TaskManager. The ID is assigned once the JobManager (or its SlotPool) first requests the slot and is constant across retries.

This ID is used by the TaskManager and ResourceManager to track and synchronize which slots are allocated to which JobManager and which are free.

In contrast to this AllocationID, the SlotRequestId is used when a task requests a logical slot from the SlotPool. Multiple logical slot requests can map to one physical slot request (due to slot sharing).
