Connecting Apache Kafka® Clients to Confluent Cloud

The confluentinc/examples GitHub repo provides hello world examples of Kafka clients connecting to Confluent Cloud in many different programming languages, including Java, Python, Go, Scala, Confluent CLI, Ruby, Groovy, Kotlin, Node, kafkacat, .NET, C, Clojure, and others. All the examples include a producer and consumer, and where relevant, Avro data with Confluent Cloud Schema Registry.

Prerequisites:
  • Before connecting a client application to Confluent Cloud, you should increase the timeout for API version requests from the default value of 10 seconds. You can change this with librdkafka api.version.request.timeout.ms parameter. For more information, see the librdkafka configuration documentation.
  • Depending on your operating system and configuration, you might have to specify the location of your client config for SSL (ssl.ca.location). For example, if your OS does not provide root CA certificates, or if the certificates are stored in a non-standard location.

Connecting to Confluent Cloud from a .NET Application

You can configure the Confluent .NET Client for Kafka to connect to a Kafka cluster in Confluent Cloud.

  1. Install the Confluent .NET Client for Apache Kafka.
  2. Customize the .NET Confluent Cloud example for your Confluent Cloud cluster, specifically bootstrap.servers, sasl.username, and sasl.password.
  3. Integrate with your environment.

Connecting to Confluent Cloud from a Go Application

You can configure the Confluent Golang Client for Kafka to connect to a Kafka cluster in Confluent Cloud.

  1. Install the Confluent Golang Client for Apache Kafka.

    Important

    The Confluent Golang Client for Kafka depends on librdkafka, which must be installed separately.

  2. Customize the Golang Confluent Cloud example for your Confluent Cloud cluster, specifically bootstrap.servers, sasl.username, and sasl.password.

  3. Integrate with your environment.

Connecting to Confluent Cloud from a Python Application

You can configure the Confluent Python Client for Kafka to connect to a Kafka cluster in Confluent Cloud.

  1. Install the Confluent Python Client for Apache Kafka.
  2. Customize the Python Confluent Cloud example for your Confluent Cloud cluster, specifically bootstrap.servers, sasl.username, and sasl.password.
  3. Integrate with your environment.
