How to check Kafka version information

Introduction

Apache Kafka is a distributed stream processing Platform that allows you to build real-time data pipelines and process large amounts of data. Kafka's high throughput, low latency, and fault tolerance make it ideal for building real-time data applications.

View Kafka version information

To view Kafka version information, you can use the following method:

• Use command line

kafka-topics --version

• Using Java API

Properties properties = new Properties();
properties.put("bootstrap.servers", "localhost:9092");

KafkaAdminClient adminClient = KafkaAdminClient.create(properties);
DescribeClusterResult result = adminClient.describeCluster();

System.out.println("Kafka version: " + result.clusterId());

Example

The following is one Example of viewing Kafka version information:

$ kafka-topics --version
kafka_2.12-2.8.0

The output shows that the current Kafka version is 2.8.0.

Other information

In addition to viewing Kafka version information, you can also use the following command to view other information:

• View the Kafka cluster ID

kafka-topics --describe --topic test

The output contains the following information:

Cluster ID: N4lU-8KdQ5y2zUwDj82sAw

• View the Kafka topic list

kafka-topics --list

The output results contain the following information:

test

• View Kafka topic details

kafka-topics --describe --topic test

The output results contain the following information:

Topic: test
PartitionCount: 1
ReplicationFactor: 1
Configs:
    cleanup.policy=delete
    compression.type=producer
    follower.replication.throttled.replicas=
