Apache Kafka - Real-time Stream Processing (Master Class) - Creating and using AVRO schema in Producers

This video tutorial guides you through the process of generating Avro serializable POJOs from schema definitions and using them in a Kafka producer program. It covers setting up a Maven project with necessary dependencies, replicating an Avro to Pojo project, and modifying a POS simulator to send Avro serialized messages. The tutorial also includes testing the project and ensuring it works with the Confluent platform and Schema Registry.

What is the primary purpose of using the Confluent Schema Registry in this project?

• To serialize data using XML

• To convert Avro to JSON

• To manage Avro schemas

• To store JSON schemas

Which version of Confluent is used in the project setup?

• Confluent 5.0

• Confluent 6.0

• Confluent 5.3.0

• Confluent 4.0

Why is it necessary to use the Confluent Kafka version in this project?

• To avoid using Apache Kafka

• To use the latest features of Kafka

• To reduce the size of the project

• To ensure compatibility with the Confluent platform

What additional plugin is required for generating Java classes from Avro schema?

• Hibernate Plugin

• Spring Boot Plugin

• Avro Maven Plugin

• Maven Compiler Plugin

What is the main change in the POS simulator when switching from JSON to Avro?

• Using a different programming language

• Adding more producer threads

• Changing the serialization format

• Using a different database

What is a key requirement for the Confluent Avro Serializer to function?

• An XML parser

• A specific database setup

• A JSON configuration file

• A running Schema Registry

What is the purpose of the scripts added in the final section?

• To automate testing

• To generate Avro schemas

• To start services and run the simulator

• To compile Java classes

Why can't the content of Avro messages be easily understood?

• They are in XML format

• They are in binary format

• They are encrypted

• They are compressed

What is a fundamental difference between the JSON and Avro projects?

• The database used

• The serialization format

• The number of producer threads

• The programming language used

What should you do if you encounter warnings during the project setup?

• Restart the Confluent platform

• Recompile after adjusting the POM file

• Ignore them

• Switch to a different version of Java
