A sliding window is a data structure that moves along a sequence of elements, retaining only a fixed-size sub-sequence at any given moment. In PySpark, it can be used for real-time processing where the data keeps arriving in a stream. The DStream API allows you to define sliding windows using slideBy() and windowByDuration(). For example:nn`windowSpec = SlidingWindow(10, 5)`nThis creates a sliding window of size 10 with a stride of 5.
