This tutorial/crash course video is about ksqlDB, where I introduce ksqlDB and explain how to use it.
I implement a real life use case, where we learn how to create a stream, insert data into the stream, select data from stream, consume events, aggregate data and store into tables, joins two streams and emit result in a kafka topic for consumption.
