Your events have a contract
Every event type is registered, versioned, and validated before delivery. One source of truth.
Events flow between organizations.
Nobody tracks what data is shared.
Nobody enforces schemas.
Nobody manages versions.
A breaking change propagates silently.
Consumers discover it in production.
Governance exists on paper.
Not in the infrastructure.
Until now.
One registry for every event type.
Every event is registered in the catalogue with its schema, owner, and subscribers. Validation blocks invalid payloads before delivery.
Evolve without breaking anyone.
Backward compatibility checks on every version change. Consumers upgrade at their own pace.
Register Version
Define the schema, version, and access rules. The schema is the contract.
Compatibility Check
Backward compatibility verified automatically. Breaking changes are blocked.
Deliver
Subscribers declare their expected version. Negotiation is automatic.
Only the latest value per key.
Configuration, pricing tables, feature flags, and state sync. Compacted channels retain only the most recent value for each key. Storage stays constant regardless of update frequency.
Years of history at cold storage prices.
Events migrate automatically from hot to warm to cold based on your policies. All tiers remain queryable.
Hot
Recent events, instant access. For real time workloads and the most frequent queries.
Warm
Older events, fast queries. Automatic cost reduction without sacrificing performance.
Cold
Years of history at the lowest cost. Remains queryable. Automatic migration by age policy.
Before and after Data Governance
Without Data Governance
- No schema registry for events
- Breaking changes propagate silently
- No version negotiation between services
- Events stored in one tier forever
- Governance exists on paper only
- Consumers discover breaking changes in production
With Data Governance
- Searchable catalogue of every event type
- Backward compatibility checked on every version
- Automatic version negotiation per subscriber
- Hot warm and cold tiers with automatic migration
- Platform enforced governance rules
- Invalid events rejected at publish time
