FAQPage Schema

How do I define event sourcing schemas for business facts in Cody Engine?▼

Event sourcing schemas for business facts are defined by specifying structured payload details, state transformation rules, and metadata visibility attributes. This approach ensures consistent data modeling for reliable event-sourced systems.

What is the best way to model state transformations when an event occurs?▼

Model state transformations by applying event payload data to update aggregate state using predefined templates. This ensures accurate state management and consistent data schema application for business fact records.

How do I configure event classification and metadata for state management?▼

Configure event classification and metadata by setting visibility attributes and application patterns within the event specification. This controls how business fact records are categorized and applied for accurate state updates.

Can I use this to specify event payloads like Order Shipped or User Registered?▼

Yes, you can model events like Order Shipped or User Registered by defining detailed schemas with timestamps and status updates. This establishes structured payloads and enforces rules for reliable state changes.

What are the limitations of modeling event sourcing without consistent schema constraints?▼

Without consistent schema constraints, event sourcing implementations risk unreliable state updates and inaccurate data modeling. Defining event specifications explicitly prevents these issues by enforcing strict payload rules and metadata classification.
