Interface | Description |
---|---|
BroadcastKey<K> |
Marker interface for a key in the snapshot state that indicates the
corresponding entry should be broadcast to all processors
when restoring the snapshot.
|
DefaultPartitionStrategy |
A facade that hides the details of Hazelcast partitioning SPI and exposes
just the partitioning strategy.
|
Inbox |
A subset of
Queue<Object> API restricted to the consumer side,
with additional support for bulk draining operations. |
Outbox |
Data sink for a
Processor . |
Partitioner<T> |
Encapsulates the logic associated with a
DAG edge that decides
on the partition ID of an item traveling over it. |
Processor |
When Jet executes a DAG, it creates one or more instances of
Processor on each cluster member to do the work of a given vertex. |
Processor.Context |
Context passed to the processor in the
init() call. |
ProcessorMetaSupplier |
Factory of
ProcessorSupplier instances. |
ProcessorMetaSupplier.Context |
Context passed to the meta-supplier at init time on the member that
received a job request from the client.
|
ProcessorSupplier |
Factory of
Processor instances. |
ProcessorSupplier.Context |
Context passed to the supplier in the
init() call. |
WatermarkEmissionPolicy |
A policy object that decides when when the watermark has advanced
enough to emit a new watermark item.
|
WatermarkPolicy |
A policy object that decides on the watermark in a single data
(sub)stream.
|
Class | Description |
---|---|
AbstractProcessor |
Base class to implement custom processors.
|
CloseableProcessorSupplier<E extends Processor & Closeable> |
A
ProcessorSupplier which closes created processor instances
when the job is complete. |
DAG |
Describes a computation to be performed by the Jet computation engine.
|
Edge | |
JetDataSerializerHook |
A Java Service Provider hook for Hazelcast's Identified Data Serializable
mechanism.
|
Partitioner.Default |
Partitioner which applies the default Hazelcast partitioning strategy.
|
ResettableSingletonTraverser<T> |
Traverses over a single item which can be set from the outside, by using
this traverser as a
Consumer<T> . |
Vertex |
Represents a unit of data processing in a Jet computation job.
|
Watermark |
Watermark is an item occasionally inserted into a disordered
(sub)stream of timestamped items.
|
WatermarkPolicies |
Utility class with factories of several useful watermark policies.
|
WindowDefinition |
Contains parameters that define a sliding/tumbling window over which Jet
will apply an aggregate function.
|
Enum | Description |
---|---|
Edge.RoutingPolicy |
An edge describes a connection from many upstream processors to many
downstream processors.
|
JobStatus |
Represents current status of the job from the perspective of the job coordinator.
|
TimestampKind |
Enumerates the two possible kinds of timestamp: event timestamp and
frame timestamp.
|
Exception | Description |
---|---|
JobNotFoundException |
Thrown when a job could not be found on the master node
|
TopologyChangedException |
Thrown when a topology change causes a job to abort.
