Java Producer Callback

This video tutorial explains how to implement a callback function in a Kafka producer to handle message metadata and exceptions. It covers creating a logger using SLF4J to log metadata details such as topic, partition, offset, and timestamp. The tutorial also demonstrates error handling and running the code to observe the output. Finally, it shows how to use a loop to send multiple records and discusses the distribution of messages across partitions.

What is the significance of the timestamp in the record metadata?

How does the producer determine which partition to send messages to?

What happens when no keys are used in message production?
