You need a custom serializer when: Your team uses Protobuf or MessagePack and wants native support You need a compact binary format for high-throughput topics (pricing ticks, sensor readings) You’re integrating with a legacy system that publishes a fixed binary protocol You want deterministic serialization for event deduplication or content-addressed storage The Serializer and Deserializer Interfaces // org.https://devops-monk.com/tutorials/spring-kafka/json-serialization/Mon, 04 May 2026 00:00:00 +0000https://devops-monk.com/tutorials/spring-kafka/json-serialization/The Serialization Problem Kafka stores bytes.
