Mitigating Silent JSON Schema Drift in Microservices: Pre-Validation Engine Patterns and the Portability Pitfall

When microservices communicate asynchronously via message brokers or REST endpoints, schema evolution is inevitable. However, without strict automated governance, small, undocumented schema alterations—known as silent schema drift —frequently cascade into catastrophic deserialization and parsing failures downstream. This article dissects the design and engineering of an automated pre-validation…
