Class Summary

Class	Description
ConfigurationNotAllowedMessage	If DeploymentOptions.PROGRAM_CONFIG_ENABLED is disabled, this error denotes the not allowed configuration.
DefaultJobManagerRunnerRegistry	DefaultJobManagerRunnerRegistry is the default implementation of the JobManagerRunnerRegistry interface.
Dispatcher	Base class for the Dispatcher component.
DispatcherCachedOperationsHandler	A handler for async operations triggered by the Dispatcher whose keys and results are cached.
DispatcherId	Fencing token of the Dispatcher.
DispatcherOperationCaches	Encapsulates caches for results of asynchronous operations triggered by the Dispatcher.
DispatcherRestEndpoint	REST endpoint for the Dispatcher component.
DispatcherServices	Dispatcher services container.
FileExecutionGraphInfoStore	Store for ExecutionGraphInfo instances.
MemoryExecutionGraphInfoStore	ExecutionGraphInfoStore implementation which stores the ArchivedExecutionGraph in memory.
MiniDispatcher	Mini Dispatcher which is instantiated as the dispatcher component by the JobClusterEntrypoint.
NoOpDispatcherBootstrap	A DispatcherBootstrap which submits the provided job graphs for execution upon dispatcher initialization.
OnMainThreadJobManagerRunnerRegistry	OnMainThreadJobManagerRunnerRegistry implements JobManagerRunnerRegistry guarding the passed JobManagerRunnerRegistry instance in a way that it only allows modifying methods to be executed on the component's main thread.
PartialDispatcherServices	Partial DispatcherServices services container which needs to be completed before being given to the Dispatcher.
PartialDispatcherServicesWithJobPersistenceComponents	DispatcherFactory services container.
SingleJobJobGraphStore	JobGraphStore implementation for a single job.
StandaloneDispatcher	Dispatcher implementation which spawns a JobMaster for each submitted JobGraph within in the same process.

Enum Summary

Enum	Description
Dispatcher.ExecutionType	Enum to distinguish between initial job submission and re-submission for recovery.
JobDispatcherFactory	DispatcherFactory which creates a MiniDispatcher.
JobMasterServiceLeadershipRunnerFactory	Factory which creates a JobMasterServiceLeadershipRunner.
SessionDispatcherFactory	DispatcherFactory which creates a StandaloneDispatcher.
TriggerSavepointMode	Describes the context of taking a savepoint: Whether it is a savepoint for a running job or whether the job is cancelled, suspended or terminated with a savepoint.
VoidHistoryServerArchivist	No-op implementation of the HistoryServerArchivist.

Exception Summary

Exception	Description
DispatcherException	Base class for Dispatcher related exceptions.
JobCancellationFailedException	JobCancellationFailedException is thrown if the cancellation of a job failed.
OperationAlreadyFailedException	Exception indicating that a requested operation already exists and has failed.
UnavailableDispatcherOperationException	Exception indicating that a Dispatcher operation is temporarily unavailable.
