What is Sliding Window

Question

I've been working for a couple of months on Apache Spark, but I want to know the significance of Sliding Window operation?

Answer 1

Sliding Window controls transmission of data packets between various computer networks. Spark Streaming library provides windowed computations where the transformations on RDDs are applied over a sliding window of data. Whenever the window slides, the RDDs that fall within the particular window are combined and operated upon to produce new RDDs of the windowed DStream.
