ExecutionSlotAllocatorFactory	Interface for ExecutionSlotAllocator factories.
GlobalFailureHandler	An interface for handling global failures.
InputsLocationsRetriever	Component to retrieve the inputs locations of an ExecutionVertex.
InternalFailuresListener	This interface enables subscribing to failures that are detected from the JobMaster side (e.g., from within the ExecutionGraph).
MutableVertexParallelismStore	Mutability extension to the VertexParallelismStore.
OperatorCoordinatorHandler	Handler for the OperatorCoordinators.
PreferredLocationsRetriever	Component to retrieve the preferred locations of an execution vertex.
SchedulerNG	Interface for scheduling Flink jobs.

StateLocationRetriever	Component to retrieve the state location of an execution vertex.
SyncPreferredLocationsRetriever	Component to retrieve the preferred locations of an execution vertex.
VertexParallelismInformation	Manages the parallelism properties for a vertex in the execution graph, as well as how they can change during runtime.
VertexParallelismStore	Contains the max parallelism per vertex, along with metadata about how these maxes were calculated.

Class Summary

Class	Description

SimpleExecutionSlotAllocator.Factory	Factory to instantiate a SimpleExecutionSlotAllocator.
SlotSharingExecutionSlotAllocatorFactory	Factory for SlotSharingExecutionSlotAllocator.
SsgNetworkMemoryCalculationUtils	Util to analyze inputs & outputs of ExecutionJobVertex and calculate network memory requirement for slot sharing group (SSG).
UpdateSchedulerNgOnInternalFailuresListener	Calls SchedulerNG.updateTaskExecutionState(TaskExecutionStateTransition) on task failure.
VertexEndOfDataListener	Records the end of data event of each task, and allows for checking whether all tasks of a JobGraph have reached the end of data.
