How do I configure a Kafka producer?

To configure a Kafka producer, you'll need to set properties like 'bootstrap.servers', 'key.serializer', and 'value.serializer'. Would you like details on each?

Yes, please explain the 'bootstrap.servers' property.

'bootstrap.servers' is a comma-separated list of Kafka broker addresses that the producer will connect to. It's essential for establishing a connection.

What about the serializers?

The 'key.serializer' and 'value.serializer' properties define how the keys and values of the messages are converted to bytes. Common options include StringSerializer and ByteArraySerializer.

Can you give me an example of a configuration in code?

Sure! Here's a simple example in Java:

Properties props = new Properties();
props.put("bootstrap.servers", "localhost:9092");
props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");
props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");

This sets up a basic producer configuration.
