public static class SourceRDD.Bounded<T>
extends org.apache.spark.rdd.RDD<org.apache.beam.sdk.util.WindowedValue<T>>
SourceRDD.Bounded
reads input from a BoundedSource
and creates a Spark RDD
.
This is the default way for the SparkRunner to read data from Beam's BoundedSources.Constructor and Description |
