In PySpark, DStream stands for Discretized Stream. It is a group of information or gathering of RDDs separated into little clusters. It is also known as Apache Spark Discretized Stream and is used as a gathering of RDDs in the grouping. DStreams are based on Spark RDDs and are used to enable Streaming to flawlessly coordinate with some other Apache Spark segments like Spark MLlib and Spark SQL.
