Event Sourcing Migrator Skill
Migrates applications to event-sourcing architecture, handling event extraction from existing data, event store setup, and CQRS implementation.
Purpose
Enable event sourcing migration for:
- Event extraction from existing data
- Event store setup
- Projection generation
- CQRS implementation
- Snapshot management
Capabilities
1. Event Extraction from Existing Data
- Analyze current state
- Derive historical events
- Generate event streams
- Handle data gaps
2. Event Store Setup
- Configure event store
- Set up partitioning
- Define retention
- Implement subscriptions
3. Projection Generation
- Create read models
- Build projections
- Handle updates
- Manage consistency
4. CQRS Implementation
- Separate read/write
- Implement commands
- Handle queries
- Manage eventual consistency
5. Snapshot Management
- Define snapshot strategy
- Generate snapshots
- Handle restoration
- Optimize performance
6. Event Replay
- Replay events
- Rebuild projections
- Handle migrations
- Test consistency
