Automating event validation with Amazon EventBridge Schema Discovery

This article discusses automating event validation in event-driven architectures using Amazon EventBridge Schema Discovery and Amazon API Gateway. Key insights include:

• Event validation is crucial for maintaining data integrity in both producer and consumer systems
• EventBridge Schema Discovery automatically generates and tracks event schema versions
• Two main approaches for schema management are presented:
  • Lambda Driven Schema Updater
  • CI/CD Driven Schema Updater
• Schema validation can be performed using:
  • API Gateway request validation
  • Code bindings for various programming languages
  • Third-party schema validation libraries

The solution aims to minimize custom validation logic, improve data quality, and reduce maintenance overhead in event-driven architectures.
