Publish an Avro event to an Amazon EventBridge custom event bus, decoded against an AWS Glue Schema Registry, and deliver it as JSON to AWS Lambda.
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 Python 3.14 AWS Lambda function, an Amazon SQS dead-letter queue, and the delivery role.
