This section describes how to connect with the JDBC DriverManager or ApacheKafkaDataSource interfaces.

Connecting with the DriverManager

When connecting with the DriverManager class, the CData JDBC Driver for Apache Kafka follows the JDBC convention: First, load the ApacheKafka driver class. Then, make a connection.

Load the Driver

The following step is optional per the JDBC 4.0 specification.

Class.forName("cdata.jdbc.apachekafka.ApacheKafkaDriver");

Establish a Connection

Provide the connection string with the getConnection method of the static DriverManager class. Start the connection string with "jdbc:apachekafka:". A typical connection string is the following:

Connection conn = DriverManager.getConnection("jdbc:apachekafka:User=admin;Password=pass;BootStrapServers=localhost:9091");

Alternatively, you can prepare the connection options using a Properties object. Pass the Properties object to the DriverManager.

prop.setProperty("User","admin");
prop.setProperty("Password","pass");
prop.setProperty("BootStrapServers","localhost:9091");

Connection conn = DriverManager.getConnection("jdbc:apachekafka:",prop);

Connecting with the ApacheKafkaDataSource Class

You can use the ApacheKafkaDataSource class to create pooled connections, as shown in the following example. See Connection Pooling for more information.

The following example instantiates a pooled Connection object:

ApacheKafkaDataSource ds = new ApacheKafkaDataSource("jdbc:apachekafka:UseConnectionPooling=true;User=admin;Password=pass;BootStrapServers=localhost:9091"); 
Connection conn = ds.getConnection();
