Introducing AWS Lambda native support for Avro and Protobuf formatted Apache Kafka events

Compute Blog

AWS Lambda now provides native support for Apache Avro and Protocol Buffers (Protobuf) formatted events when using Kafka Event Source Mapping in Provisioned Mode.

  • Offers built-in integration with AWS Glue Schema Registry, Confluent Cloud, and self-managed schema registries
  • Automatically validates incoming JSON, Avro, and Protobuf records against registered schemas
  • Supports multiple schema registries with automatic caching and schema evolution
  • Provides two event record formats: SOURCE (preserves binary format) and JSON (deserializes data)
  • Enables event filtering before Lambda function invocation to reduce costs

This new capability simplifies Kafka event processing by moving complex schema registry integration from application code to the managed Lambda service, allowing developers to focus on business logic.
