Yeva Byzek takes us through the Kafka Connect Datagen connector:
Short of using real data from a real source, you do have a few options on how to generate more interesting test data for your topics. One option is to write your own client. Kafka has many programming language options—you choose: Java, Python, Go, .NET, Erlang, Rust—the list goes on. You can write your own Kafka client applications that produce any kind of records to a Kafka topic, and then you’re set.
But wouldn’t it be great if you could generate data locally to just fill topics with messages? Fortunately, you’re in luck! Because we have those data generators.
