What is io.confluent.connect.jdbc.jdbcsourceconnector and How to Download It for Data Exchange
How to Download io.confluent.connect.jdbc.jdbcsourceconnector
If you want to import data from any relational database with a JDBC driver into an Apache Kafka topic, you can use the Kafka Connect JDBC Source connector. This connector can support a wide variety of databases and query modes, and it can run in standalone or distributed mode. In this article, we will show you how to download and configure the connector, and how to use it to stream data from a database into Kafka.

What is io.confluent.connect.jdbc.jdbcsourceconnector and what does it do?
The io.confluent.connect.jdbc.jdbcsourceconnector is a Java class that implements the SourceConnector interface of Kafka Connect. It is part of the Confluent Platform, which is a distribution of Apache Kafka that provides additional features and integrations. The connector allows you to periodically execute a SQL query against a database and create an output record for each row in the result set. The output records are then sent to a Kafka topic, where they can be consumed by other applications or connectors.
What are the benefits and use cases of using it?
Using the JDBC source connector has several benefits and use cases, such as:
It simplifies data integration between databases and Kafka, as you don't need to write any custom code or use any intermediate tools.
It supports incremental query modes, which means that it can track which rows have been processed and which rows are new or updated, and only fetch the relevant data from the database.
It enables you to stream data from multiple tables or schemas, using whitelists or blacklists, or custom queries.
It enables you to leverage the scalability and fault-tolerance of Kafka Connect, as you can run the connector in standalone or distributed mode, depending on your needs.
It enables you to use Kafka as a central hub for data pipelines, streaming analytics, data integration, and mission-critical applications.
Prerequisites
Before you can download and configure the JDBC source connector, you need to have the following prerequisites:
A relational database with a JDBC driver. For this article, we will use MySQL as an example, but you can use any database that has a compatible driver.
A Kafka cluster with at least one broker and one ZooKeeper node. You can use Confluent Platform or Apache Kafka to set up your cluster.
Kafka Connect, which is included in Confluent Platform or Apache Kafka. You need to have at least one Kafka Connect worker node running.
The JDBC driver for your database. You need to download the driver JAR file and place it in a directory that is accessible by Kafka Connect.
How to install Kafka Connect and JDBC driver?
To install Kafka Connect, you can follow the instructions from , depending on which distribution you are using. You can run Kafka Connect in standalone mode (for development and testing) or distributed mode (for production).
To install the JDBC driver for your database, you can follow these steps:
