This lecture covers the use of schema registry and Kafka Avro console producer to publish and consume messages with a defined schema. It explains the steps to create a schema, publish messages, and validate them against the schema. The lecture also addresses handling serialization errors and highlights the advantages of using schema registry for ensuring data consistency.

What is the main focus of this lecture compared to the previous one?

• Interacting with a broker container

• Using a different JVM process

• Creating and using a schema

• Publishing schema-less messages

What is a key difference when using the Kafka Avro console producer?

• It allows passing the schema as part of the producer

• It is part of the broker distribution

• It does not interact with the schema registry

• It does not require a schema

Why is it necessary to log into the schema registry before running certain commands?

• To format the schema

• To access the broker list

• To use the Kafka Avro console producer

• To create a greetings topic

What indicates that a message is published with the correct schema?

• The process getting killed

• Not receiving any error messages

• Seeing a parsing exception

• Receiving a syntax error

What happens if a message does not match the registered schema?

• The process gets killed due to a serialization error

• The process continues without issues

• The message is automatically corrected

• The message is published as a string

What is the advantage of using a schema registry with Avro?

• It guarantees a fixed data structure

• It allows for schema-less message production

• It simplifies the command line interface

• It eliminates the need for a broker

What is the role of the byte array serializer in the process?

• It converts JSON to a byte array

• It converts JSON to a string

• It formats the schema into multiple lines

• It reads bytes and converts them to a string
