4.2 Producing Messages: Command Line & Best Practices

http://centralmesh.io Chapter 4: Basic Kafka Operations In this section, we focus on producing messages to Kafka using CLI tools, covering how keys, partitions, and schemas affect message distribution and data integrity. You’ll learn: How Kafka producers send messages to topics using the console producer. How message keys influence partition assignment and ordering. How Kafka distributes messages without keys using round-robin partitioning. Why using keys ensures related messages are routed to the same partition. How partitions enable parallelism while preserving per-key ordering. How Kafka integrates with Schema Registry to enforce data structure. Why Avro schemas are commonly used with Kafka for efficient serialization. How schema validation prevents incompatible or malformed data from being written to Kafka. What happens when a producer sends data that violates the registered schema. The role of the producer versus Kafka brokers in schema validation. By the end of this section, you’ll be able to: Produce messages to Kafka with and without keys. Explain how keys control partitioning and message ordering. Choose when to use keyless versus keyed message production. Produce schema-validated messages using Avro and Schema Registry. Understand how schema enforcement protects consumers from bad data. Troubleshoot common producer and serialization errors.
