Package org.apache.beam.runners.spark.io

Class SourceRDD.Bounded<T>

  • All Implemented Interfaces:
    java.io.Serializable, org.apache.spark.internal.Logging, scala.Serializable
    Enclosing class:
    SourceRDD
    public static class SourceRDD.Bounded<T>
extends org.apache.spark.rdd.RDD<org.apache.beam.sdk.util.WindowedValue<T>>
    A 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.
