Standardize event contracts across SAP S/4HANA, SAP Event Mesh, and Apache Kafka. Generate production AsyncAPI 3.0 specification documents, JSON Schema validation definitions, and schema registry compatibility rules.
Complete contracts, Event Mesh, and CloudEvents patterns in The SAP BTP & Business AI Architecture Companion.
Just as OpenAPI standardizes REST endpoints, AsyncAPI 3.0 establishes machine-readable contracts for channels, operations, and message payloads across SAP and external clouds.
Adding optional fields maintains backward compatibility. Removing fields or altering data types constitutes a breaking change and requires a major version increment in topic namespace.
Incorporate schema linters into pipeline quality gates (Tool #79) to catch incompatible event mutations before pull requests merge into the core repository.
Part of the SAP Clean Core Engineering Suite • Cross-referenced with Tool #83 (Kafka Architect) and Tool #41 (Topic Matrix)
