Sekiban DCB - Dynamic Consistency Boundary

Sekiban DCB is the recommended event sourcing implementation for new projects. It uses tag-based consistency boundaries instead of traditional aggregates, enabling more flexible cross-entity transactions without saga complexity.

📚 Documentation: sekiban.dev

Sekiban Implementations

Implementation Description Status
Sekiban DCB Dynamic Consistency Boundary - tag-based event sourcing ✅ Recommended
Sekiban.Pure Traditional aggregate-based event sourcing ⚠️ Deprecated

Quick Start

dotnet new install Sekiban.Pure.Templates

Key Features

  • Tag-based consistency: Define consistency scope per command, not per aggregate
  • No saga complexity: Cross-entity invariants without compensating events
  • Optimistic concurrency: Tag-based conflict detection with SortableUniqueId
  • Actor model: Microsoft Orleans integration for scalability
  • Multi-cloud: Azure (Cosmos DB) and AWS (DynamoDB) support

What is DCB?

Dynamic Consistency Boundary (DCB) replaces rigid per-aggregate transactional boundaries with context-sensitive consistency based on event tags. Each event carries tags representing affected entities, and consistency is enforced only on the tags reserved by a command.
