composable-rust-event-sourcing
Composable Rust Event Sourcing Expert
Expert knowledge for implementing event sourcing patterns in Composable Rust - event store design, state reconstruction, version tracking, PostgreSQL integration, and CQRS patterns.
When to Use This Skill
Automatically apply when:
- Implementing event-sourced aggregates
- Working with
EventStoretrait or PostgreSQL event store - Designing event schemas or event types
- Implementing state reconstruction from events
- Dealing with optimistic concurrency or version tracking
- Questions about event sourcing, CQRS, or persistence
Event Sourcing Fundamentals
Core Principle
State is derived from events, not stored directly.
