Serde
A Serde is a component that provides serialization and deserialization for a particular data type.
Kafka Streams in Action, Second Edition
Serdes is a Kafka Streams utility class that provides factory methods for standard Serde implementations.
- How it is used
- Configures Kafka Streams source, sink, and state boundaries to convert byte-array records into typed keys and values.
- How deep it goes
- Defines Serdes, catalogs built-ins, constructs custom pairs with serdeFrom, and defers serializer and deserializer implementation details.
- Examples
- Uses a string-based Yelling app, retail purchase objects, rewards output, and a KTable of stock trades.
- What you can do after
- Apply it via Kafka Streams APIs to configure typed stream sources, sinks, state stores, custom objects, and Schema Registry formats.

Akka in Action, Second Edition
A SerDe is a serializer-deserializer component that converts structured data to and from a storable or transferable representation.
- How it is used
- Restores persistent actor events and carries structured messages between application objects and journal representations.
- How deep it goes
- Explains storage bindings, serializer identifiers, and version compatibility, but stops short of custom serializer implementation details.
- Examples
- Uses evolving AddCargo and CargoAdded events plus a journal table containing binary payloads and serializer identifiers.
- What you can do after
- Operate/configure event persistence and evaluate serializer strategies for safely reading older event schemas.
