Introduction to Kafka Connectors
In this section, we will explore Kafka Connectors and their role in data integration within the Apache Kafka ecosystem. Kafka Connectors provide an efficient and reliable way to integrate external systems with Kafka, enabling seamless data ingestion and export. Understanding Kafka Connectors is crucial for building scalable and robust data pipelines.
Topics covered in this section:
- Overview of Kafka Connect and its architecture.
- Understanding source connectors and their role in data ingestion.
- Exploring sink connectors and their role in data export.
- Key features and benefits of Kafka Connectors.
- Configuring and managing Kafka Connectors.
Code Sample: Configuring a Kafka Source Connector
name=my-source-connector
connector.class=org.apache.kafka.connect.source.SourceConnectorClass
tasks.max=1
topic=my_topic

Building a Custom Kafka Connector
In this section, we will explore the process of building a custom Kafka Connector. While Kafka provides a wide range of built-in connectors, there might be cases where you need to develop a connector tailored to your specific use case. Understanding the steps involved in building a custom connector empowers you to extend Kafka’s integration capabilities.
Topics covered in this section:
- Understanding the connector development lifecycle.
- Defining the connector configuration and tasks.
- Implementing the connector logic for source or sink operations.
- Packaging and deploying the custom connector.
- Testing and validating the custom connector.
Code Sample: Custom Kafka Connector Configuration
public class MyCustomConnectorConfig extends ConnectorConfig {
public static final String MY_CUSTOM_CONFIG = "my.custom.config";
public MyCustomConnectorConfig(Map<String, String> props) {
super(config(), props);
}
public static ConfigDef config() {
return new ConfigDef()
.define(MY_CUSTOM_CONFIG, ConfigDef.Type.STRING, ConfigDef.Importance.HIGH, "My custom configuration");
}
}
