Once marked "solved" are done for some part with the examples of Purchases events as in the video, but later also with ClickEvents. Faust is another open-source stream processing library which ports the ideas from Kafka Streams to Python. Rather than relying on a message queue, Kafka appends messages to the log and leaves them there, where they remain until the consumer reads it or reaches its retention limit.
