Apache Spark - Streaming - DStream

==DStream==

Discretized stream or DStream represents a continuous stream of data. DStream can be created either from input data streams or by applying higher-level operations to other DStreams. We will learn higher-level operations later in the course.

DStream is represented as a sequence of RDDs internally. We write Spark Streaming programs using DStreams.
