Kafka Consumer and producer

Let's first start the zookeeper.
open a new command window, and run the following command.

zookeeper-server-start %KAFKA_HOME%\config\zookeeper.properties

zookeeper by default, starts at port 2181.


start the kafka server.
open a new command window, and run the following command.

kafka-server-start %KAFKA_HOME%\config\server.properties

create a topic called hello-topic with 4 partitions and replication factor of 1.
open a new command window, and run the following command.

kafka-topics --create --topic hello-topic --partitions 4 --replication-factor 1 --zookeeper localhost:2181

start a kafka console producer to send messages to the topic

kafka-console-producer --topic hello-topic --bootstrap-server localhost:9092

start a kafka console consumer to receive messages from the topic

kafka-console-consumer --topic hello-topic --bootstrap-server localhost:9092

Start typing messages in producer and it will reach to consumer.
