Event Registry
Event Registry — Part of the Governed, Unified, Model-Driven Real-Time Data Platform Suite (GUM-RTDP)
What It Does
The Event Registry is the design-time authority application for every business and AI event flowing through your enterprise. Where the EDA Platform governs event streaming at runtime, the Event Registry governs the event contract before a single line of code is written — defining what every event is, what version it carries, and what lifecycle status it holds. Architects define the JSON payload specification. Developers reference it. Governance is enforced through discipline with no tax at execution time.
Every event type referenced in implementation code points back to the Event Registry through a simple event_type + version key. This is the payload specification contract — authoritative, versioned, and stable. When new attributes are added to a payload, a new version is created in the registry. Existing consumers are unaffected — their code references the version they implemented and continues to work unchanged. If and when they choose to adopt the new version, the specification is right there in the registry.
The Event Registry is independently deployable — organizations already operating an event-driven infrastructure, whether based on Apache Kafka, Confluent, Solace, Tibco, or any other platform, can adopt the Event Registry to add design-time event contract governance without replacing or modifying their existing architecture.
Core Governance Principles
The Event Registry is built on three principles that distinguish it from runtime schema registries:
- Registry governs what exists and when. Every event type and every version is architect-controlled. No event enters an environment without a corresponding registry entry — governed through discipline, not runtime overhead.
- No payload in the registry. The registry is a design-time authority, not a schema store. Payload specification is accessed through the
event_type+versionkey — the contract between architects and developers. - Environment-driven lifecycle. Event types are promoted through customer-defined environments — typically development, integration, user acceptance, pre-production, and production, though the environment table is fully configurable to match any organization's promotion pipeline.
Why the Event Registry
Zero runtime cost. Governance is enforced through discipline — the registry operates entirely at design time with no infrastructure overhead at execution time. There is nothing to monitor, nothing to fail, and nothing that adds latency to your event pipeline.
Consumer stability. When a new version is created, existing consumers are unaffected. Their code references the version they implemented and continues to work unchanged. Consumers adopt new versions on their own terms, on their own timeline.
Parallel publishing without chaos. Breaking changes are managed at the registry level — event contract continuity across topics is a governed registry operation, not a coordination problem scattered across development teams.
Configurable to any organization. The environment table adapts to any promotion pipeline. No rigid opinionated workflow is imposed — the registry conforms to how your organization already promotes from development to production.
Single source of truth. One place where architects and developers align on what every event is, what version it carries, and what its payload specification contains. Ambiguity is eliminated at the source.
No vendor lock-in on payload. JSON keeps the contract open and portable. No proprietary schema format, no registry-specific serialization — your event contracts belong to your organization.
Parallel Publishing
When a breaking change requires parallel publishing, the Event Registry manages event contract continuity across topics without impact on existing code.
What the Event Registry Includes
The Event Registry is a deployable application including: a PostgreSQL-backed event type catalog, full version history per event type, customer-configurable environment-driven lifecycle management, topic and domain organization, event_type + version payload specification contract, parallel publishing support, and documentation.
Technology Foundation
Built on PostgreSQL — proven, enterprise-grade, and operationally simple. The Event Registry requires no additional infrastructure beyond what most enterprises already operate.
The Event Registry is part of the GUM-RTDP suite alongside the EDA Platform, Lakehouse Platform, and Data Governance Platform. Binary licensed for enterprise deployment.
