What is Kafka Streams serialization?

Can you explain what Kafka Streams serialization is?

Kafka Streams serialization refers to the process of converting data into a format suitable for transmission and storage in Kafka. It ensures that data can be efficiently processed and consumed by different applications.

What are the common serialization formats used in Kafka Streams?

Common serialization formats include Avro, JSON, and Protobuf. Each has its own advantages depending on the use case, such as schema evolution or human readability.

How do I implement serialization in my Kafka Streams application?

To implement serialization, you need to configure your Kafka Streams application with the appropriate Serdes (Serializer/Deserializer) for your data types. For example, you can use Serdes.String() for string data or create custom Serdes for complex objects.

Can you give an example of a custom Serde?

Sure! A custom Serde can be created by implementing the Serde interface and defining how to serialize and deserialize your specific data type. This allows you to handle complex objects in your Kafka Streams application.
