Stratara.Projections

License: MIT.

Projection runtime for the Stratara event-sourced stack. Discovers IProjection implementations in the consumer's application assemblies, dispatches event bundles to them, and applies the resulting change sets atomically via the read-model repository layer.

What's in the box

Folder Contents
Services/ ProjectionManager (event-bundle → matching projection-handlers fan-out), ProjectionHandler<TEvent> base class, ProjectionMethodInvoker (reflection-cached method-pointer dispatch into consumer projections), checkpoint plumbing
Multitenancy/ TenantProjection — the framework's own opinionated tenant aggregate projection. Skip the registration if your application has its own tenancy model
Diagnostics/Extensions/ Source-generated LoggerProjectionExtensions, LoggerChangeSetExtensions, LoggerUpdateExtensions — typed [LoggerMessage] surfaces under the Stratara.Projection.* / Stratara.ChangeSet.* / Stratara.Update.* event-ID bands

Quick start

// In your EventProjection worker:
builder.Services.AddProjectionsFromAssemblyContaining<MyAppProjectionMarker>();

Then implement IProjection in your application assembly. The projection manager picks them up automatically.

Dependencies

  • Stratara.Contracts — for EventBundle + IEvent<T>.
  • Stratara.Domain — for the framework's Tenant aggregate (only consumed by TenantProjection).
  • Stratara.Shared — for change-tracking primitives, reflection cache, partitioning helpers, diagnostics base.
  • Microsoft.Extensions.Hosting.Abstractions + Microsoft.Extensions.Options.ConfigurationExtensions — for projection-worker checkpointing options.
  • JetBrains.Annotations — for static-analysis attributes on projection-handler conventions.

Package Downloads
Stratara.EventSourcing.EntityFrameworkCore

EF Core persistence for the Stratara event-sourced stack on PostgreSQL — write-store, read-store, ASP.NET Identity store, shared conventions, value generators, and UnitOfWork primitives. Targets Npgsql with pgvector.
Stratara.EventSourcing.WorkerDefaults

Worker-host wiring composites for the Stratara event-sourced stack. IHostApplicationBuilder extensions (AddBackendServices, AddCommandWorkerServices, AddEventProjectionWorkerServices, AddSagaWorkerServices, AddOutboxWorkerServices) bundle the per-concern DI calls so each worker host opts in with one line.

### Added

- **Event upcasting (`IEventUpcaster`).** Persisted events can now be transformed from an older
 on-disk schema into the shape the current event record expects, applied on read before the payload
 is deserialized. Register upcasters with `AddEventUpcaster<TUpcaster>()`; each implements
 `IEventUpcaster` (`SourceEventTypeName` / `TargetEventTypeName` plus `JsonNode Upcast(JsonNode)`) and
 they chain across successive schema versions (v1→v2→v3), including event-type renames — the source
 type no longer needs to exist in the assembly. Matching ignores the assembly `Version` segment, and
 a cyclic or duplicate-source chain is rejected. Hosts that register no upcasters are unaffected
 (transparent pass-through). Snapshots are not upcasted — change an aggregate's shape and rebuild its
 snapshots.

### Changed

- **Copyright holder corrected to the full legal name "Norbert Heinz Rosenwinkel"** in the `LICENSE`
 file and in the `Authors` / `Copyright` package metadata. No code or licensing-terms change — the
 license remains MIT.
