Classes in org.apache.tez.runtime.api used by org.apache.tez.dag.api

Class and Description
Event Base class for all events generated within the Tez execution engine.
InputSpecUpdate Update Input specs for Inputs running in a task.
VertexStatistics Provides various statistics about the physical execution of this Vertex This only provides point in time values for the statistics and values are refreshed based on when the implementations of the inputs/outputs/tasks etc.

InputStatisticsReporter Report statistics about the Input
LogicalInput An Input which handles all incoming physical connections on an edge.
LogicalInputFrameworkInterface Defines the framework facing interfact for a LogicalInput User implementations are expected to derive from AbstractLogicalInput
LogicalIOProcessor Represents a processor which consumes LogicalInputs and produces LogicalOutputs
LogicalIOProcessorFrameworkInterface Represents a processor framework interface which consumes LogicalInputs and produces LogicalOutputs.
LogicalOutput An @link Output which handles all outgoing physical connections on an edge.
LogicalOutputFrameworkInterface Framework facing interface for the LogicalOutput Users are expected to derive from AbstractLogicalOutput
MemoryUpdateCallback This interface will be used by Tez to inform components about available memory.
MergedInputContext Context for MergedLogicalInput This interface is not supposed to be implemented by users
ObjectRegistry A simple shared object registry to cache objects in the memory of the container running the task.
Output Represents an Output through which a TezProcessor writes information to an edge.
OutputCommitterContext Context through which the OutputCommitter can access all the relevant information that it needs.
OutputContext Context handle for the Output to initialize itself.
OutputFrameworkInterface Represents the Tez framework part of an Output.
OutputStatistics Provides various statistics about physical execution activity happening on a logical output in a Vertex.
OutputStatisticsReporter Report statistics about the Output
Processor Processor represents the Tez entity responsible for consuming Input and producing Output.
ProcessorContext Context handle for the Processor to initialize itself.
ProcessorFrameworkInterface Represents the Tez framework part of an Processor.
Reader A Reader represents the data being read in an Input It encapsulates the data type etc of the data being provided by the Input E.g.
TaskContext Base interface for Context classes used to initialize the Input, Output and Processor instances.
Writer A Writer represents the data being written by an Output It encapsulates the data type etc of the data being provided by the Output E.g.
