Stratara.Domain

License: FSL-1.1-MIT (Functional Source License — source-available; converts to MIT after 2 years). Not OSI-approved OSS.

The Stratara framework's concrete multitenancy domain — the Tenant aggregate and its event vocabulary. Use this when your application wants Stratara's opinionated tenant model (one tenant per customer, lifecycle events for activate / deactivate / rename / locale-change / assignment) and the corresponding aggregate.

Contents

  • Stratara.Domain.Multitenancy.Tenant — the aggregate. Implements IAggregate (from Stratara.Abstractions).
  • Stratara.Domain.TenantCreated / TenantRenamed / TenantActivated / TenantDeactivated / TenantDefaultLocaleChanged / TenantAssignedToCustomer / TenantDeleted / CustomerTenantsDeleted — the event records consumed by the aggregate's Apply() methods + persisted to the event stream.

When to skip this package

If you're building a Stratara-on-Mediator application without the framework's tenant model (e.g. you have your own tenancy concept), reference Stratara.Abstractions alone for the marker interfaces. Most Stratara features (CQRS, event sourcing, projections, sagas) don't depend on Stratara.Domain.

Quick reference

// Open a Tenant stream from a command handler
await events.CreateAsync<Tenant>(tenantId,
    new TenantCreated(
        Id: tenantId,
        CustomerId: customerId,
        Name: "Acme",
        DefaultLocale: "de-DE",
        IsActive: true,
        CreatedAt: DateTimeOffset.UtcNow),
    cancellationToken);
await events.SaveChangesAsync(cancellationToken);

// Later: rehydrate the aggregate
var tenant = await aggregator.AggregateAsync<Tenant>(tenantId, cancellationToken: cancellationToken);

Dependencies

  • Stratara.Abstractions — for IAggregate (Tenant implements it).
  • JetBrains.Annotations — for static-analysis attributes.

Package Downloads
Stratara.Shared

Umbrella package for the Stratara framework — source-generated logger extensions for outbox / saga / projection / messaging, domain-event helpers, merge primitives, and the Tier-A/B abstractions surface re-exported as one transitive bundle.
Stratara.Projections

Projection runtime for the Stratara event-sourced stack — projection-handler discovery, change-set creation, update application, and projection manager. Sits between read-model repositories and the event-bundle dispatcher.
Stratara.Sagas

Saga runtime for the Stratara event-sourced stack — ISaga discovery, manager / handler dispatch, cached method invoker, and a hosted SagaWorker that routes incoming event bundles to matching sagas.

### Added

- **Mediator tenant-isolation behavior** (`Stratara.Mediator`) — `AddStrataraTenantIsolation()`
 registers a pipeline behavior that enforces tenant isolation at the mediator entrance, before the
 handler runs, for any request that opts in via the new `ITenantScopedRequest` marker
 (`Stratara.Abstractions.Multitenancy`). The behavior compares the request's `TenantId` (data owner)
 against the ambient session's data-owner tenant and rejects a mismatch with the new
 `TenantAccessDeniedException` (translated to HTTP 403 on ASP.NET hosts). `TenantIsolationMode.Default`
 enforces only the subject match (privileged cross-tenant operations pass when the endpoint promoted
 the session subject to the target); `TenantIsolationMode.Strict` additionally routes every
 cross-tenant operation through the new `ICrossTenantAuthorizer`, whose shipped default denies all
 cross-tenant access until a consumer registers its own authorizer. Complements the existing
 database-side `ApplyGlobalTenantQueryFilters` with a command-/query-entrance guard. New log-event
 IDs `114_101`/`114_102`/`114_003` in `Stratara.Diagnostics`.
- **`Stratara.Abstractions.Persistence.ConcurrencyConflictException`** — provider-agnostic
 wrapper for an optimistic-concurrency conflict detected during commit. Allows framework-level
 code in `Stratara.Projections` (and any consumer outside the `EntityFrameworkCore` package) to
 react to concurrency without taking an EF Core dependency. EF Core's `DbUpdateConcurrencyException`
 (and provider equivalents) flow through this type.

### Changed

- **`EfTransaction.SaveChangesAsync`** (in `Stratara.EventSourcing.EntityFrameworkCore`) now
 wraps `DbUpdateConcurrencyException` thrown by EF Core in the new
 `ConcurrencyConflictException`. PostgreSQL unique-violation paths remain on `DbUpdateException`
 (different semantics — duplicate-key on insert vs. stale-row on update/delete).
- **`EventSource.SaveChangesAsync`** (write-side append flow) extends its concurrency-handling
 catch to the new exception type so the existing append-conflict recovery path keeps working
 after the wrap. Behaviour for both EF concurrency conflicts and PostgreSQL unique violations
 is unchanged.

### Fixed

- **`TenantProjection` no longer aborts the event bundle on a parallel delete race.** The two
 delete handlers (`TenantDeleted`, `CustomerTenantsDeleted`) now swallow
 `ConcurrencyConflictException` silently — a missing row is the desired end-state of a delete.
 Before this fix, a consumer-side customer-delete cascade saga that emits both
 `CustomerTenantsDeleted` and a follow-up `TenantDeleted` for the same tenants would race the
 two parallel projection bundles on the same `TenantView` row; the loser threw
 `DbUpdateConcurrencyException` out of `SaveChangesAsync`, which propagated through
 `ProjectionWorker` and caused `RabbitMqBus` to roll back the entire bundle — including
 sibling projections that had already committed. Update handlers (rename / activate /
 deactivate / locale / customer-assigned) keep their current behaviour: a concurrency failure
 there is a real race that propagates.
