Several tools/scripts are included in the bin directory of the Apache Kafka binary installation. Even if that directory has a number of scripts, through this article, I want to highlight the five scripts/tools that I believe will have the biggest influence on your development work, mostly related to real-time data stream processing.
After setting up the development environment, followed by installation and configuration of either with single-node or multi-node Kafka cluster, the first built-in script or tool is kafka-topic.sh.
