1. Introduction

Kafka is a popular distributed streaming platform that allows you to publish and subscribe to streams of data, process them in real-time, and store them in a scalable and fault-tolerant way. Kafka can be used for various use cases, such as messaging, analytics, event-driven applications, and data integration.

But what if you want to integrate Kafka with external systems, such as databases, APIs, or cloud services? How can you easily move data between Kafka and these systems without writing a lot of custom code or using complex tools?

This is where Kafka Connect comes in. Kafka Connect is a framework that allows you to connect Kafka with external systems, using a set of pre-built connectors that can handle common data formats and protocols. Kafka Connect simplifies the process of data integration, by providing a uniform and scalable way to configure, manage, and monitor data pipelines between Kafka and other systems.

In this blog, you will learn how to use Kafka Connect with Python to integrate with external systems. You will learn how to use different connectors and configurations to integrate with various sources and sinks. You will also learn how to use the Kafka Connect APIs to interact with Kafka Connect programmatically, and how to monitor and troubleshoot Kafka Connect issues.

By the end of this blog, you will be able to use Kafka Connect with Python to create data pipelines that can move data between Kafka and any external system you want.

Are you ready to get started? Let’s dive in!

2. What is Kafka Connect?

Kafka Connect is a framework that enables you to easily integrate Kafka with external systems, such as databases, APIs, or cloud services. Kafka Connect provides a set of connectors that can handle common data formats and protocols, and allows you to configure them using a simple JSON file. You can also write your own custom connectors if you need to support a specific system or data format.

Kafka Connect works by running a cluster of workers that can scale up or down depending on the load. Each worker can run one or more connector instances, which are responsible for moving data between Kafka and the external system. A connector can have two types of tasks: source tasks and sink tasks. Source tasks read data from the external system and write it to Kafka topics, while sink tasks read data from Kafka topics and write it to the external system.

Kafka Connect has two modes of operation: standalone and distributed. In standalone mode, you run a single worker process that executes all the connector tasks. This mode is useful for development and testing, but not for production. In distributed mode, you run multiple worker processes that form a cluster and share the connector tasks. This mode is recommended for production, as it provides high availability, fault tolerance, and scalability.

Kafka Connect also has two APIs that you can use to interact with it programmatically: the Python API and the REST API. The Python API allows you to write Python scripts that can create, configure, and manage connectors. The REST API allows you to use HTTP requests to perform the same operations. You can use either API to monitor and troubleshoot Kafka Connect issues, such as checking the status, logs, and metrics of the workers and the connectors.

Kafka Connect is a powerful and flexible framework that can help you integrate Kafka with any external system you want. But how do you use it with Python? That’s what you will learn in the next section.

3. How to Install and Run Kafka Connect

Before you can use Kafka Connect with Python, you need to install and run Kafka Connect on your machine or cluster. In this section, you will learn how to do that in a few simple steps.

First, you need to have Kafka installed and running on your machine or cluster. You can follow the official Kafka quickstart guide to download and start Kafka. You will also need to create a topic that you will use for your data integration. For example, you can create a topic called test with the following command:


bin/kafka-topics.sh --create --topic test --bootstrap-server localhost:9092

Next, you need to download and extract Kafka Connect from the Kafka downloads page. You can choose the same version as your Kafka installation. For example, you can download Kafka Connect 2.8.0 with the following command:


wget https://downloads.apache.org/kafka/2.8.0/kafka_2.13-2.8.0.tgz
tar -xzf kafka_2.13-2.8.0.tgz

Now, you are ready to run Kafka Connect in standalone or distributed mode. In standalone mode, you run a single worker process that executes all the connector tasks. This mode is useful for development and testing, but not for production. To run Kafka Connect in standalone mode, you need to provide a worker configuration file and a connector configuration file. The worker configuration file specifies the basic settings for the worker, such as the bootstrap servers, the converters, and the offset storage. The connector configuration file specifies the settings for the connector, such as the name, the class, the topics, and the custom properties. You can find some example configuration files in the config directory of Kafka Connect. For example, you can run Kafka Connect in standalone mode with the following command:


bin/connect-standalone.sh config/connect-standalone.properties config/connect-file-source.properties

This command will start a worker that runs a file source connector, which reads data from a file and writes it to a Kafka topic. You can modify the configuration files to suit your needs, or create your own configuration files for different connectors.

In distributed mode, you run multiple worker processes that form a cluster and share the connector tasks. This mode is recommended for production, as it provides high availability, fault tolerance, and scalability. To run Kafka Connect in distributed mode, you only need to provide a worker configuration file. The connector configuration file will be submitted later through the REST API. The worker configuration file specifies the basic settings for the worker, as well as the group ID, the config storage, the status storage, and the offset storage. You can find an example configuration file in the config directory of Kafka Connect. For example, you can run Kafka Connect in distributed mode with the following command:


bin/connect-distributed.sh config/connect-distributed.properties

This command will start a worker that joins a cluster with the specified group ID. You can run multiple workers with the same configuration file to form a cluster. You can then use the REST API to create, configure, and manage connectors on the cluster.

Congratulations, you have successfully installed and run Kafka Connect on your machine or cluster. You are now ready to use Kafka Connect with Python to integrate with external systems. How do you do that? You will find out in the next section.

4. How to Use Kafka Connect with Python

Kafka Connect provides two APIs that you can use to interact with it programmatically: the Python API and the REST API. In this section, you will learn how to use both APIs to create, configure, and manage connectors with Python. You will also learn how to use the kafka-python library to produce and consume data from Kafka topics with Python.

The Python API is a wrapper around the REST API that allows you to write Python scripts that can perform the same operations as the REST API. The Python API is available as a kafka-connect package that you can install with pip. To use the Python API, you need to import the KafkaConnect class and create an instance with the URL of the Kafka Connect cluster. For example, you can create a KafkaConnect object with the following code:


from kafka_connect import KafkaConnect
kc = KafkaConnect("http://localhost:8083")

The KafkaConnect object has several methods that correspond to the REST API endpoints. For example, you can use the get_connectors method to get a list of all the connectors on the cluster, or the create_connector method to create a new connector with a given configuration. You can also use the get_connector, update_connector, delete_connector, pause_connector, resume_connector, restart_connector, get_connector_status, get_connector_config, get_connector_tasks, and restart_connector_task methods to perform various operations on a specific connector. You can find the full documentation of the Python API here.

The REST API is a HTTP-based API that allows you to use any HTTP client to send requests to the Kafka Connect cluster. The REST API has several endpoints that correspond to the operations that you can perform on the cluster and the connectors. For example, you can use the /connectors endpoint to get a list of all the connectors on the cluster, or to create a new connector with a POST request. You can also use the /connectors/{name} endpoint to perform various operations on a specific connector, such as getting, updating, deleting, pausing, resuming, or restarting the connector. You can also use the /connectors/{name}/status, /connectors/{name}/config, /connectors/{name}/tasks, and /connectors/{name}/tasks/{id}/restart endpoints to get or modify the status, configuration, tasks, or task restart of a specific connector. You can find the full documentation of the REST API here.

The kafka-python library is a Python client for Apache Kafka that allows you to produce and consume data from Kafka topics with Python. The kafka-python library is available as a kafka-python package that you can install with pip. To use the kafka-python library, you need to import the KafkaProducer and KafkaConsumer classes and create instances with the bootstrap servers and other optional parameters. For example, you can create a KafkaProducer object and a KafkaConsumer object with the following code:


from kafka import KafkaProducer, KafkaConsumer
producer = KafkaProducer(bootstrap_servers="localhost:9092")
consumer = KafkaConsumer("test", bootstrap_servers="localhost:9092")

The KafkaProducer object has a send method that allows you to send a message to a Kafka topic. The message can be a byte array, a string, or a serialized object. The KafkaConsumer object has an __iter__ method that allows you to iterate over the messages from a Kafka topic. The messages are ConsumerRecord objects that have attributes such as topic, partition, offset, key, and value. You can also use the poll, subscribe, unsubscribe, assign, seek, commit, and close methods to perform various operations on the consumer. You can find the full documentation of the kafka-python library here.

You have learned how to use Kafka Connect with Python to integrate with external systems. You have learned how to use the Python API and the REST API to create, configure, and manage connectors, and how to use the kafka-python library to produce and consume data from Kafka topics. You can use these tools to create data pipelines that can move data between Kafka and any external system you want. But how do you configure the connectors to suit your needs? That’s what you will learn in the next section.

4.1. Kafka Connect Python API


from kafka_connect import KafkaConnect
kc = KafkaConnect("http://localhost:8083")

To illustrate how to use the Python API, let’s create a simple connector that reads data from a file and writes it to a Kafka topic. We will use the file source connector, which is one of the built-in connectors that come with Kafka Connect. We will also use the JSON converter, which converts the data to and from JSON format. We will assume that you have a file called data.txt in your current directory, and that you have a Kafka topic called test that you want to write the data to. You can use any text editor to create the file and write some data to it, such as:


Hello, world!
This is a test.
Kafka Connect is awesome.

To create the connector, we need to define a configuration dictionary that specifies the name, the class, the topics, and the custom properties of the connector. For example, we can define the configuration dictionary as follows:


config = {
    "name": "file-source-connector",
    "connector.class": "FileStreamSource",
    "tasks.max": "1",
    "file": "data.txt",
    "topic": "test",
    "key.converter": "org.apache.kafka.connect.json.JsonConverter",
    "value.converter": "org.apache.kafka.connect.json.JsonConverter",
    "key.converter.schemas.enable": "false",
    "value.converter.schemas.enable": "false"
}

Then, we can use the create_connector method of the KafkaConnect object to create the connector with the configuration dictionary. For example, we can create the connector with the following code:


kc.create_connector(config)

This will return a JSON response that confirms the creation of the connector and shows the configuration details. You can also use the get_connector method to get the same information. For example, you can get the connector information with the following code:


kc.get_connector("file-source-connector")

This will return a JSON response that shows the name, the config, and the tasks of the connector. You can also use the get_connector_status method to get the status of the connector, such as the state, the worker, and the trace. For example, you can get the connector status with the following code:


kc.get_connector_status("file-source-connector")

This will return a JSON response that shows the status of the connector and its tasks. You can also use the get_connector_config method to get the configuration of the connector, such as the class, the topics, and the custom properties. For example, you can get the connector configuration with the following code:


kc.get_connector_config("file-source-connector")

This will return a JSON response that shows the configuration of the connector. You can also use the get_connector_tasks method to get the tasks of the connector, such as the ID, the config, and the status. For example, you can get the connector tasks with the following code:


kc.get_connector_tasks("file-source-connector")

This will return a JSON response that shows the tasks of the connector. You can also use the restart_connector_task method to restart a specific task of the connector, by providing the task ID. For example, you can restart the task 0 of the connector with the following code:


kc.restart_connector_task("file-source-connector", 0)

This will return an empty response that indicates the successful restart of the task. You can also use the update_connector method to update the configuration of the connector, by providing a new configuration dictionary. For example, you can update the connector to read from a different file with the following code:


new_config = {
    "name": "file-source-connector",
    "connector.class": "FileStreamSource",
    "tasks.max": "1",
    "file": "new_data.txt",
    "topic": "test",
    "key.converter": "org.apache.kafka.connect.json.JsonConverter",
    "value.converter": "org.apache.kafka.connect.json.JsonConverter",
    "key.converter.schemas.enable": "false",
    "value.converter.schemas.enable": "false"
}
kc.update_connector("file-source-connector", new_config)

This will return a JSON response that shows the updated configuration of the connector. You can also use the delete_connector method to delete the connector, by providing the name of the connector. For example, you can delete the connector with the following code:


kc.delete_connector("file-source-connector")

This will return an empty response that indicates the successful deletion of the connector. You can also use the pause_connector method to pause the connector, by providing the name of the connector. For example, you can pause the connector with the following code:


kc.pause_connector("file-source-connector")

This will return an empty response that indicates the successful pause of the connector. You can also use the resume_connector method to resume the connector, by providing the name of the connector. For example, you can resume the connector with the following code:


kc.resume_connector("file-source-connector")

This will return an empty response that indicates the successful resume of the connector. You can also use the restart_connector method to restart the connector, by providing the name of the connector. For example, you can restart the connector with the following code:


kc.restart_connector("file-source-connector")

This will return an empty response that indicates the successful restart of the connector.

You have learned how to use the Python API to create, configure, and manage connectors with Python. You have also learned how to use the file source connector to read data from a file and write it to a Kafka topic. You can use the same approach to use other connectors that are available in Kafka Connect, or write your own custom connectors if you need to. But how do you use the REST API to do the same things? That’s what you will learn in the next section.

4.2. Kafka Connect REST API

Another way to interact with Kafka Connect programmatically is to use the REST API. The REST API allows you to use HTTP requests to perform various operations on Kafka Connect, such as creating, deleting, listing, and configuring connectors. You can also use the REST API to check the status, logs, and metrics of the workers and the connectors.

To use the REST API, you need to know the URL of the Kafka Connect cluster. By default, the URL is http://localhost:8083, but you can change it by modifying the rest.port and rest.host.name properties in the worker configuration file. You can also use the rest.advertised.host.name, rest.advertised.port, and rest.advertised.listener properties to control how the cluster advertises itself to other systems.

The REST API supports the following HTTP methods: GET, POST, PUT, DELETE, and PATCH. You can use any HTTP client to send requests to the REST API, such as curl, Postman, or Python requests. The requests and responses are in JSON format, so you need to set the Content-Type and Accept headers accordingly. You can also use the Accept-Encoding header to request compressed responses.

The REST API has several endpoints that correspond to different operations on Kafka Connect. Here are some examples of the most common endpoints and how to use them:

/connectors: This endpoint allows you to list, create, and delete connectors. For example, to list all the connectors in the cluster, you can use the following GET request:
```
curl -X GET http://localhost:8083/connectors
```
To create a new connector, you can use the following POST request with a JSON payload that specifies the connector name, class, and configuration:
```
curl -X POST -H "Content-Type: application/json" --data '{"name": "my-connector", "class": "org.apache.kafka.connect.file.FileStreamSourceConnector", "config": {"topic": "my-topic", "file": "/tmp/my-file"}}' http://localhost:8083/connectors
```
To delete a connector, you can use the following DELETE request with the connector name as a parameter:
```
curl -X DELETE http://localhost:8083/connectors/my-connector
```
/connectors/{name}: This endpoint allows you to get, update, and restart a connector by its name. For example, to get the status and configuration of a connector, you can use the following GET request:
```
curl -X GET http://localhost:8083/connectors/my-connector
```
To update the configuration of a connector, you can use the following PUT request with a JSON payload that specifies the new configuration:
```
curl -X PUT -H "Content-Type: application/json" --data '{"config": {"topic": "my-new-topic", "file": "/tmp/my-new-file"}}' http://localhost:8083/connectors/my-connector
```
To restart a connector, you can use the following POST request:
```
curl -X POST http://localhost:8083/connectors/my-connector/restart
```
/connectors/{name}/tasks: This endpoint allows you to list, create, delete, and restart the tasks of a connector by its name. For example, to list the tasks of a connector, you can use the following GET request:
```
curl -X GET http://localhost:8083/connectors/my-connector/tasks
```
To create a new task for a connector, you can use the following POST request with a JSON payload that specifies the task id and configuration:
```
curl -X POST -H "Content-Type: application/json" --data '{"id": 0, "config": {"topic": "my-topic", "file": "/tmp/my-file"}}' http://localhost:8083/connectors/my-connector/tasks
```
To delete a task for a connector, you can use the following DELETE request with the task id as a parameter:
```
curl -X DELETE http://localhost:8083/connectors/my-connector/tasks/0
```
To restart a task for a connector, you can use the following POST request with the task id as a parameter:
```
curl -X POST http://localhost:8083/connectors/my-connector/tasks/0/restart
```
/connectors/{name}/status: This endpoint allows you to get and put the status of a connector by its name. For example, to get the status of a connector, you can use the following GET request:
```
curl -X GET http://localhost:8083/connectors/my-connector/status
```
To put the status of a connector, you can use the following PUT request with a JSON payload that specifies the new status:
```
curl -X PUT -H "Content-Type: application/json" --data '{"state": "PAUSED"}' http://localhost:8083/connectors/my-connector/status
```
/connectors/{name}/config: This endpoint allows you to get and put the configuration of a connector by its name. For example, to get the configuration of a connector, you can use the following GET request:
```
curl -X GET http://localhost:8083/connectors/my-connector/config
```
To put the configuration of a connector, you can use the following PUT request with a JSON payload that specifies the new configuration:
```
curl -X PUT -H "Content-Type: application/json" --data '{"topic": "my-new-topic", "file": "/tmp/my-new-file"}' http://localhost:8083/connectors/my-connector/config
```
/connector-plugins: This endpoint allows you to list and validate the connector plugins available in the cluster. For example, to list the connector plugins, you can use the following GET request:
```
curl -X GET http://localhost:8083/connector-plugins
```
To validate the configuration of a connector plugin, you can use the following PUT request with a JSON payload that specifies the connector class and configuration:
```
curl -X PUT -H "Content-Type: application/json" --data '{"class": "org.apache.kafka.connect.file.FileStreamSourceConnector", "config": {"topic": "my-topic", "file": "/tmp/my-file"}}' http://localhost:8083/connector-plugins/FileStreamSourceConnector/config/validate
```

These are some of the most common endpoints of the REST API, but there are more that you can explore in the official documentation. The REST API is a powerful and convenient way to interact with Kafka Connect, especially if you want to automate or integrate your data pipelines with other systems. However, if you prefer to use Python code instead of HTTP requests, you can use the Python API, which we covered in the previous section.

5. How to Configure Kafka Connectors

One of the most important aspects of using Kafka Connect is to configure the connectors properly. The configuration of a connector determines how it interacts with the external system, such as what data to read or write, how to format or transform the data, and how to handle errors or failures. The configuration of a connector also affects the performance and reliability of the data pipeline, such as how much data to buffer, how often to commit, and how to balance the load among the tasks.

The configuration of a connector is a JSON object that consists of key-value pairs. The keys are the names of the configuration properties, and the values are the values of the properties. The configuration properties can be divided into two categories: common and connector-specific. Common properties are the ones that apply to all connectors, such as name, class, tasks.max, and topics. Connector-specific properties are the ones that are specific to a particular connector, such as file, database.url, or aws.access.key.id.

The configuration properties can have different types, such as string, integer, boolean, list, or class. Some properties can also have default values, validators, converters, or recommenders. The default values are the values that are used if the property is not specified. The validators are the functions that check if the value of the property is valid. The converters are the functions that convert the value of the property from one type to another. The recommenders are the functions that suggest possible values for the property based on the context.

To configure a connector, you need to provide a JSON object that contains the required and optional properties for the connector. You can use the /connector-plugins/{name}/config/validate endpoint of the REST API to validate the configuration of a connector before creating or updating it. You can also use the config method of the Python API to get or set the configuration of a connector programmatically. Here is an example of a valid configuration for a file source connector:

{
  "name": "file-source-connector",
  "class": "org.apache.kafka.connect.file.FileStreamSourceConnector",
  "tasks.max": 1,
  "topics": "file-topic",
  "file": "/tmp/file.txt"
}

This configuration specifies the name, class, maximum number of tasks, topics, and file path for the connector. The name and class properties are required, while the others are optional with default values. The file property is specific to the file source connector, and it indicates the file to read data from. The topics property is common to all source connectors, and it indicates the topics to write data to.

You can use different configuration properties to customize the behavior of the connector according to your needs. For example, you can use the transforms property to apply one or more transformations to the data before writing it to Kafka. You can also use the errors.tolerance and errors.deadletterqueue.topic.name properties to control how the connector handles errors or failures. You can find the complete list of the configuration properties and their descriptions in the official documentation.

Configuring the connectors correctly is essential for creating reliable and efficient data pipelines with Kafka Connect. In the next section, you will learn how to monitor and troubleshoot Kafka Connect issues, and how to optimize the performance and reliability of your data pipelines.

5.1. Source Connectors

Source connectors are the connectors that read data from external systems and write it to Kafka topics. They are useful for ingesting data from various sources, such as files, databases, APIs, or cloud services, into Kafka. Source connectors can also transform or enrich the data before writing it to Kafka, such as adding timestamps, headers, or schemas.

Kafka Connect provides a number of built-in source connectors that can handle common data formats and protocols, such as file, JDBC, HTTP, S3, or Twitter. You can also find many community-developed source connectors that can support other systems or formats, such as MongoDB, Salesforce, or XML. You can also write your own custom source connectors if you need to support a specific system or format that is not available.

To use a source connector, you need to specify the connector class and the configuration properties in a JSON file. The connector class is the name of the Java class that implements the source connector logic. The configuration properties are the key-value pairs that control the behavior of the source connector, such as what data to read, how to format it, and how to write it to Kafka. The configuration properties can vary depending on the type of the source connector, but some common ones are:

name: The name of the connector. It must be unique within the cluster.
tasks.max: The maximum number of tasks that the connector can spawn. Each task is responsible for a subset of the data.
topics: The list of topics to write the data to. The topics must exist in Kafka before the connector starts.
key.converter: The converter class that converts the key of the data from the source format to the Kafka format.
value.converter: The converter class that converts the value of the data from the source format to the Kafka format.
transforms: The list of transformations to apply to the data before writing it to Kafka.

Here is an example of a source connector configuration file for a file source connector that reads data from a text file and writes it to a Kafka topic:

{
  "name": "file-source-connector",
  "class": "org.apache.kafka.connect.file.FileStreamSourceConnector",
  "tasks.max": 1,
  "topics": "file-topic",
  "file": "/tmp/file.txt",
  "key.converter": "org.apache.kafka.connect.storage.StringConverter",
  "value.converter": "org.apache.kafka.connect.storage.StringConverter"
}

This configuration specifies the name, class, maximum number of tasks, topics, file path, and converters for the connector. The file property is specific to the file source connector, and it indicates the file to read data from. The topics property is common to all source connectors, and it indicates the topics to write data to. The key.converter and value.converter properties are common to all connectors, and they indicate the converter classes to use for the key and value of the data. In this case, the data is in plain text format, so the StringConverter class is used.

You can use different source connectors and configuration properties to ingest data from various external systems into Kafka. In the next section, you will learn how to use sink connectors, which are the connectors that read data from Kafka topics and write it to external systems.

5.2. Sink Connectors

Sink connectors are the opposite of source connectors. They read data from Kafka topics and write it to external systems, such as databases, APIs, or cloud services. Sink connectors can be used for various purposes, such as data replication, backup, analytics, or reporting.

To use a sink connector, you need to specify the following parameters in the connector configuration file:

connector.class: The name of the connector class that implements the sink connector logic.
topics: The list of Kafka topics that the sink connector will consume data from.
tasks.max: The maximum number of sink tasks that the sink connector can spawn.
key.converter and value.converter: The converters that will convert the Kafka record keys and values to the format expected by the external system.
name: The name of the sink connector.
Other connector-specific parameters that define the connection details and the behavior of the sink connector.

For example, here is a sample configuration file for a sink connector that writes data from a Kafka topic named orders to a PostgreSQL database table named orders:

{
  "connector.class": "io.confluent.connect.jdbc.JdbcSinkConnector",
  "topics": "orders",
  "tasks.max": "1",
  "key.converter": "org.apache.kafka.connect.storage.StringConverter",
  "value.converter": "io.confluent.connect.avro.AvroConverter",
  "value.converter.schema.registry.url": "http://localhost:8081",
  "connection.url": "jdbc:postgresql://localhost:5432/postgres",
  "connection.user": "postgres",
  "connection.password": "postgres",
  "auto.create": "true",
  "insert.mode": "upsert",
  "pk.mode": "record_key",
  "pk.fields": "order_id",
  "name": "postgres-sink"
}

To create and run the sink connector, you can use the same commands as for the source connector, but with a different configuration file name. For example, to create the sink connector using the REST API, you can use the following command:

curl -X POST -H "Content-Type: application/json" --data @postgres-sink.json http://localhost:8083/connectors

To check the status of the sink connector, you can use the following command:

curl http://localhost:8083/connectors/postgres-sink/status

To delete the sink connector, you can use the following command:

curl -X DELETE http://localhost:8083/connectors/postgres-sink

You can find more information about the available sink connectors and their configuration options in the Confluent documentation.

Now that you know how to configure and use sink connectors, you might wonder how to monitor and troubleshoot Kafka Connect issues. That’s what you will learn in the next section.
