程序包 org.apache.flink.runtime.scheduler

接口概要

接口	说明
ExecutionGraphFactory	Factory for creating an ExecutionGraph.
ExecutionSlotAllocator	Component responsible for assigning slots to a collection of Execution.
ExecutionSlotAllocatorFactory	Interface for ExecutionSlotAllocator factories.
InputsLocationsRetriever	Component to retrieve the inputs locations of a Execution.
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.
SchedulerNGFactory	Factory for SchedulerNG.
SchedulerOperations	Component which is used by SchedulingStrategy to commit scheduling decisions.
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.
