The lecture explains session windows, which are periods of activity followed by inactivity, and how they differ from fixed-size time windows. Using a clickstream example, it demonstrates capturing user click events, streaming them to Kafka, and counting clicks per user session. The process of creating session windows in Kafka Streams is detailed, including handling late-arriving records and merging windows. The session window's behavior is illustrated with examples, highlighting its application in user behavior analysis.
