Projection Patterns
Comprehensive guide to building projections and read models for event-sourced systems.
Use this skill when
- Building CQRS read models
- Creating materialized views from events
- Optimizing query performance
- Implementing real-time dashboards
- Building search indexes from events
- Aggregating data across streams
Do not use this skill when
