This is the continuation of the [Spark Streaming Basics](/apache%20spark/2023/06/09/Spark-Streaming-part-1.html). I explained the basic stream example, which runs only on one AWS Glue container. The stream producer was Netcat, and the sink was a text file. In this post, the stream producer is still Netcat, but the sink is Kafka. Both Kafka and Spark running on Docker containers.
