Stratara.EventSourcing.WorkerDefaults
Derived. The behaviour described here is specified under
openspec/specs/. Those specifications are the source; this page explains and illustrates them.
License: MIT.
One-stop IHostApplicationBuilder composites that wire together the Stratara event-sourced stack for each host shape (API, command worker, event-projection worker, saga worker, event-stream-hash worker, outbox worker). Reference this package from each host instead of repeating the per-concern DI call chain.
What's in the box
| Composite | Wires |
|---|---|
AddBackendServices |
Common framework services (messaging, identity, session, security, mapping, resilience) + mediator + write store + outbox dispatcher. For API hosts that dispatch commands but don't process them. |
AddCommandWorkerServices |
AddCommandServices + mediator-worker (hosted service that consumes the command topic into the in-process mediator). |
AddCommandServices |
Common + mediator + write store + event sourcing + outbox dispatcher, without the mediator worker. For command silos of the Orleans execution model. |
AddEventProjectionWorkerServices |
Common + write store + projection-replay state + projection worker. |
AddEventProjectionServices |
The same without the bus-fed projection worker. |
AddSagaWorkerServices |
Common + write store + event sourcing + outbox dispatcher + saga worker. |
AddSagaServices |
The same without the bus-fed saga worker. |
AddEventStreamHashWorkerServices |
Common + write store + event-stream-hashing worker. |
AddOutboxWorkerServices |
Common + write store + outbox dispatcher + outbox-retry worker. |
The composites live in the Microsoft.Extensions.Hosting namespace so call sites read naturally:
// Command-handling worker host:
builder.AddCommandWorkerServices();
// API host that only dispatches commands:
builder.AddBackendServices();
Dependencies
This package pulls the framework's Tier-C pieces (Stratara.Infrastructure, Stratara.Outbox.RabbitMQ, Stratara.Projections, Stratara.Sagas, Stratara.EventSourcing.EntityFrameworkCore) so a single PackageReference is enough for a worker host. The lean Stratara.ServiceDefaults (OTel + Serilog) and Stratara.ServiceDefaults.AspNetCore (health-check endpoints + ASP.NET OTel) stay separate so non-worker hosts don't drag the Tier-C runtime in.

A host on the Orleans execution model can now wait until a projection has applied what it committed, instead of
reading its read model and hoping the projection is through. Additive; no schema change and no migration.
### Added
- **`IProjectionProgress`** (`Stratara.Abstractions`), registered by `AddStrataraProjectionGrains()`.
`MarkAsync()` returns a `StoreMark` that covers every entry committed at the time of the call, in every partition
— on PostgreSQL also an entry that committed while another write was still open. `WaitAsync(projection, mark,
timeout)`, with the projection named by its type or its framework name, answers with a `ProjectionWaitResult`:
`Reached` only once the projection has applied every entry the mark covers; otherwise, at the limit, `Stalled`,
`Suspended` or `TimedOut` with the partitions behind; `MarkNotApplicable` at once for a mark taken under another
reader or partition count. A rebuild or a full replay during a wait is waited through; an unknown projection is
refused. See *Read your own write* in the projection guide.
- **`ICommittedPositionReader.CommittedHeadAsync`**, the highest position the store shows as committed. The default
answers `HeadAsync`; the native PostgreSQL reader answers it without the horizon its head is held back to. A
reader of your own that holds its head back overrides it.
### Upgrade notes
- Adopt the wait once every silo runs this release: a silo of an earlier version does not answer it, and a wait
whose partition lives there fails with the grain call's error.
