Class Summary

Class	Description
ConsoleIO	Print to console.
ConsoleIO.Write	Write to console.
ConsoleIO.Write.Unbound<T>	PTransform writing PCollection to the console.
CreateStream<T>	Create an input stream from Queue.
EmptyCheckpointMark	Passing null values to Spark's Java API may cause problems because of Guava preconditions.
MicrobatchSource<T,CheckpointMarkT extends org.apache.beam.sdk.io.UnboundedSource.CheckpointMark>	A Source that accommodates Spark's micro-batch oriented nature and wraps an UnboundedSource.
SourceRDD	Classes implementing Beam Source RDDs.
SourceRDD.Bounded<T>	A SourceRDD.Bounded reads input from a BoundedSource and creates a Spark RDD.
SourceRDD.Unbounded<T,CheckpointMarkT extends org.apache.beam.sdk.io.UnboundedSource.CheckpointMark>	A SourceRDD.Unbounded is the implementation of a micro-batch in a SourceDStream.
SparkUnboundedSource	A "composite" InputDStream implementation for UnboundedSources.
SparkUnboundedSource.Metadata	A metadata holder for an input stream partition.
