This video is a hands-on guide to Flink SQL. We'll talk about how Flink works, how SQL is possible on streaming data, various components of Flink that allow SQL queries, and some major stateful, stateless and temporal Flink SQL queries you can run. The code example is for a fictitious array of IoT sensors, which we analyze in Flink and make decisions about them (e.g. if they cross a threshold by too much, issuing alerts).
