Apache Kafka Practice

In Apache Kafka, a Producer is responsible for publishing messages to one or more Kafka topics. This role is crucial as it handles the creation and sending of messages to the broker in a Kafka cluster. When a producer sends a message, it can specify the target topic, and optionally provide a key to determine the partition within that topic, ensuring that messages are distributed across partitions in a way that maintains message ordering when needed.

The producer also has various configurations that can be set to adjust the performance and reliability of message delivery, such as how many acknowledgments to wait for before considering a message sent successfully or how to handle retries in case of transient failures.

The other choices do not accurately describe the Producer’s function. For instance, consuming messages is the responsibility of a Consumer, not a Producer. Storing messages is the primary duty of the brokers in the Kafka architecture, not the producers, and while configurations are important in Kafka, they are managed at the cluster or topic level rather than by the Producer itself. Hence, stating that a Producer publishes messages to Kafka topics accurately captures its primary role in the system.
