view-to-query-model
CommunityDerive read models from view specs for CQRS.
System Documentation
What problem does it solve?
In CQRS, aggregates are optimised for enforcing invariants, not serving screens. Querying them directly couples read performance to write-side structure and blocks UI evolution on domain model changes.
A read model is a projection — it consumes domain events and maintains a denormalised, query-optimised representation shaped for one view. Each read model serves a specific view spec, updated asynchronously as events occur.
Core Features & Use Cases
- Start from the view spec (V-XX) and map fields, filters, and sorts to read model fields.
- Trace back to source events that create or modify data. A single read model typically consumes events from multiple aggregates.
- Define the schema, indexes, and staleness tolerance to match UX requirements.
- Integration test pattern to verify that consuming domain events produces the expected projection state.
Quick Start
Generate the read-model specification RM-XX from the view spec V-XX and related domain events, then create the initial projection tests.
