Kafka for Developers - Data Contracts Using Schema Registry - Serialization Formats

This lecture introduces two serialization formats for Kafka: binary and plaintext. Binary serialization is efficient and compact, while plaintext is human-readable but less efficient. Popular formats include Avro, Protocol Buffers, and Thrift for binary, and JSON and XML for plaintext. Avro is highlighted for its ease of use and schema support. The lecture concludes with a recommendation to read an article by Jacreps on Avro for Kafka.

What is the primary requirement for producers and consumers when sending data to Kafka?

• They must have the same hardware specifications.

• They must be on the same network.

• They must agree on a serialization format.

• They must use the same programming language.

Which serialization format is known for being human-readable?

• Binary

• Plaintext

• Thrift

• Protocol Buffers

Which of the following is a popular binary serialization format used with Kafka?

• Avro

• XML

• JSON

• CSV

What is a key advantage of using Avro over Protocol Buffers and Thrift?

• Avro does not require a schema.

• Avro is the only format supported by Kafka.

• Avro schema can be defined in JSON.

• Avro is faster than all other formats.

Who is credited with starting the development of Kafka?

• Elon Musk

• Jacreps

• Mark Zuckerberg

• Bill Gates
