Uses of AbstractEvent in org.apache.flink.runtime.event

Subclasses of AbstractEvent in org.apache.flink.runtime.event

Modifier and Type	Class	Description
class	RuntimeEvent	Subclasses of this event are recognized as events exchanged by the core runtime.
class	TaskEvent	Subclasses of this event are recognized as custom events that are not part of the core flink runtime.
class	WatermarkEvent	This event wraps the Watermark, it is used in propagate Watermark between shuffle components, and should not be visible to operators and functions.

Uses of AbstractEvent in org.apache.flink.runtime.io.network.api

Subclasses of AbstractEvent in org.apache.flink.runtime.io.network.api

Modifier and Type	Class	Description
class	CancelCheckpointMarker	The CancelCheckpointMarker travels through the data streams, similar to the CheckpointBarrier, but signals that a certain checkpoint should be canceled.
class	CheckpointBarrier	Checkpoint barriers are used to align checkpoints throughout the streaming topology.
class	EndOfData	This event indicates there will be no more data records in a subpartition.
class	EndOfPartitionEvent	This event marks a subpartition as fully consumed.
class	EndOfSegmentEvent	EndOfSegmentEvent is used to notify the downstream switch tiers in tiered storage shuffle mode.
class	EndOfSuperstepEvent	Marks the end of a superstep of one particular iteration superstep.
class	EventAnnouncement	EventAnnouncement is announcing presence or receiving of an AbstractEvent.
class	RecoveryMetadata	RecoveryMetadata contains the metadata used during a recovery process.
class	SubtaskConnectionDescriptor	An event that is used to (de)multiplex old channels over the same new channel.
