To create a Kafka Connect connector that reads data from an AWS RDS MySQL instance and pushes it to Kafka, you will need to follow these steps:
- Install and start Kafka Connect.
- Download and install the MySQL JDBC driver on the machine where Kafka Connect is running.
- Create a properties file for the connector, and specify the connector class, name, and the connection details for the MySQL instance. Here is an example properties file:
name=rds-mysql-source-connector connector.class=io.confluent.connect.jdbc.JdbcSourceConnector
tasks.max=1
connection.url=jdbc:mysql://<RDS_HOSTNAME>:3306/<DATABASE>?user=<USERNAME>&password=<PASSWORD>
mode=bulk
table.whitelist=<TABLE_NAME>
- Start the connector using the properties file. You can do this using the Kafka Connect REST API or the Kafka Connect CLI.
curl -X POST -H “Content-Type: application/json” –data @rds-mysql.properties http://localhost:8083/connectors
- Verify that the connector is running and data is being transferred from the MySQL instance to Kafka. You can check the connector’s status and read the data in Kafka using the Kafka CLI or a Kafka consumer application.
That’s it! You have successfully created a Kafka Connect connector to read data from an AWS RDS MySQL instance and push it to Kafka.
