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
dotnet new sekiban-orleans-aspire -n YourProjectName

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

Supported Event Stores

Event Store Package Cloud
Cosmos DB Sekiban.Dcb.CosmosDb Azure
PostgreSQL Sekiban.Dcb.Postgres Any
DynamoDB Sekiban.Dcb.DynamoDB AWS
SQLite Sekiban.Dcb.Sqlite Local/Dev

Cosmos DB — read the consistency contract first (English | 日本語). Postgres writes events and tag rows in one transaction; Cosmos writes them in two phases, so a crash can leave an event visible to all-events reads but missing from tag-scoped ones. The defaults are unchanged on upgrade (WriteFailurePolicy = Compatible); RollForward is an opt-in that retries the tag write instead of deleting events, and the tag-index repair service and automatic sweep are both opt-in registrations. If you need atomic event/tag visibility — money-sensitive workflows above all — use Postgres.

Snapshot Storage

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.

Sekiban.Dcb.Orleans.WithoutResult

Sekiban DCB Orleans WithoutResult - Orleans integration with exception-based error handling
Sekiban.Cloud.Client

Credentialed ISekibanExecutor client for Sekiban Cloud (managed) and credentialed self-hosted Sekiban Runtime. Injects service-scoped credentials via DelegatingHandler from IConfiguration / user-secrets / environment variables — no application code branches required. Credentials are mandatory and fail fast when missing; for no-auth single-tenant access use the OSS Sekiban.Dcb.WasmRuntime.Remote client instead.
Sekiban.Dcb.WasmRuntime.Remote

Sekiban DCB WASM runtime remote HTTP runner client
Sekiban.Dcb.WithoutResult.Testing

Sekiban DCB WithoutResult Testing - the in-process testing executor for the exception-based facade. Never reference this from a runtime project.
