This video covers setting an idle timeout on a watermark generator when joining data in Apache Flink. This can be used when you have two streams, one that has frequent updates, and one that has infrequent updates, and you need to join data without waiting for a fresh watermark from the infrequent one.

In this video, we'll look at some techniques for evolving events by analyzing a specific use case in a banking fraud detection system.

Additionally, isolating specific subsets of the stream for analysis or debugging often involves even more queries, adding to the complexity and time required.
