/**
* Spark Streaming functionality. [[org.apache.spark.streaming.StreamingContext]] serves as the main
* entry point to Spark Streaming, while [[org.apache.spark.streaming.dstream.DStream]] is the data
* type representing a continuous sequence of RDDs, representing a continuous stream of data.
*
* In addition, [[org.apache.spark.streaming.dstream.PairDStreamFunctions]] contains operations
* available only on DStreams
* of key-value pairs, such as `groupByKey` and `reduceByKey`. These operations are automatically
* available on any DStream of the right type (e.g. DStream[(Int, Int)] through implicit
* conversions.
*
* For the Java API of Spark Streaming, take a look at the
* [[org.apache.spark.streaming.api.java.JavaStreamingContext]] which serves as the entry point, and
* the [[org.apache.spark.streaming.api.java.JavaDStream]] and the
* [[org.apache.spark.streaming.api.java.JavaPairDStream]] which have the DStream functionality.
