Streaming data pipelines are conquering the world. Jay Kreps's Kappa architecture, first made public in 2014 (!) in his "Questioning the Lambda Architecture" article, has become part of the mainstream.

We'll also see a real-life example where we deployed the proposed architecture using Mongo, Kafka, Debezium, and Apache Spark.
