How to Set Up a Kafka Producer to Source Data Through CLI

Setting up a Kafka producer to source data through the Command Line Interface (CLI) involves a few steps. Kafka provides a command-line tool called kafka-console-producer that allows you to send messages to a Kafka topic. Here's how you can set it up:

Prerequisites:

1. Kafka Installation: Make sure you have Apache Kafka installed and running. You can download Kafka from the official Apache Kafka website and follow the instructions for installation.
2. Zookeeper and Kafka Broker(s): Ensure that Zookeeper and Kafka broker(s) are up and running.

Steps:

1. Navigate to Kafka Directory:

   Open a terminal and navigate to the directory where Kafka is installed.

2. Start the Kafka Producer:

   Use the kafka-console-producer command to start the producer. Specify the Kafka broker address (--broker-list) and the topic to which you want to send messages (--topic). For example:

                   
                       ./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic your-topic-name
                   
               

   Replace localhost:9092 with the address and port of your Kafka broker, and your-topic-name with the name of the Kafka topic you want to produce messages to.

3. Send Messages:

   Once the producer is started, you can type messages into the terminal. Each line you type will be sent as a separate message to the Kafka topic specified.

4. Send Messages with Keys (Optional):

   If you want to send messages with keys, you can specify them using the --property flag. For example:

                   
                       ./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic your-topic-name --property "parse.key=true" --property "key.separator=:"
                   
               

   This allows you to send messages with keys and values separated by a delimiter (in this case, :).

5. Send Messages from a File (Optional):

   If you have messages stored in a file and want to send them to Kafka, you can use the --file flag followed by the path to the file. For example:

                   
                       ./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic your-topic-name < your-file.txt
                   
               

   This will send the contents of the file line by line to the specified Kafka topic.

6. Exit the Producer:

   To exit the producer, simply press Ctrl + C.
