Understand the detailed analysis of Kafka version query command

Kafka version view command analysis

Kafka is a distributed stream processing platform that can process large amounts of data in real time. It was developed by the Apache Software Foundation and first released in 2011. Kafka was originally developed for LinkedIn's website activity tracking system, but now it has been widely used in various application scenarios, including log aggregation, metric monitoring, event stream processing, etc.

Kafka has many advantages, including:

• High throughput: Kafka can process millions of messages per second.
• Low latency: Kafka’s message latency is very low, usually only a few milliseconds.
• Reliability: Kafka is a very reliable system that can ensure that messages will not be lost.
• Scalability: Kafka can be easily scaled to meet growing data demands.
• Open source: Kafka is an open source software that can be used and modified for free.

Kafka version view command

To view the Kafka version, you can use the following command:

kafka-version

This command will output the Kafka version number, for example:

2.11-0.10.2.0

This version number indicates that the version of Kafka is 2.11, and the 0.10.2.0 version of Scala is used.

Code Example

The following is a code example using the Kafka version view command:

import org.apache.kafka.clients.admin.AdminClient;
import org.apache.kafka.clients.admin.KafkaAdminClient;

public class KafkaVersionExample {

  public static void main(String[] args) {
    // Create an AdminClient instance
    AdminClient adminClient = KafkaAdminClient.create();

    // Get the Kafka version
    String version = adminClient.describeCluster().version().version();

    // Print the Kafka version
    System.out.println("Kafka version: " + version);

    // Close the AdminClient instance
    adminClient.close();
  }
}

This code example uses the Kafka AdminClient to get the Kafka version Number. AdminClient is a client for managing Kafka clusters. It provides many APIs for managing Kafka clusters.

Summary

The Kafka version view command is a very simple command, but it can help you quickly understand the version number of Kafka. This is very important when you are managing a Kafka cluster, as different Kafka versions may have different functionality and features.
