This pattern shows how to publish a rich domain event, Avro-encoded, to an Amazon EventBridge custom event bus (the eventsv2 API) using PutRawEvents together with an AWS Glue Schema Registry, and then deliver that same event to an AWS Lambda subscriber.

The publisher encodes an OrderPlaced event against an Avro schema and wraps it in the AWS Glue wire format. Amazon EventBridge decodes the Avro against the AWS Glue registry server-side and delivers the payload as plain JSON, so the consumer AWS Lambda function needs no Avro library and simply logs the event to Amazon CloudWatch. A matching orderId, fields, and metadata prove the delivered event equals the one that was published.

This deploys one Amazon EventBridge custom event bus, one subscriber, an AWS Glue Schema Registry and Avro schema, one Java 21 AWS Lambda function, an Amazon SQS dead-letter queue, and the delivery role.
