kafka tutorial java

The recent project always with Java, I write a Python programmer, in the face of complex data structure of Java code into Python code, is indeed a big problem, sometimes more or less will leave a bit of a hole, it seems to have to look at the Java Foundation. This is not the beginning to let us connect Kafka again toda

Kafka officially provided two scripts to manage the topic, including additions and deletions to topic. Where kafka-topics.sh is responsible for the creation and deletion of topic, kafka-configs.sh script is responsible for topic modification and query, but many users are more inclined to use the program API to operate topic. The previous article mentioned how to
