Stratara.Infrastructure
Derived. The behaviour described here is specified under
openspec/specs/. Those specifications are the source; this page explains and illustrates them.
License: MIT.
Cross-cutting infrastructure plumbing for the Stratara framework — the Tier-C glue that lets downstream apps wire authorization, DI composition, and worker-stack configuration with a single reference.
Contents
- Authorization decorators over command-outbox dispatch (
AuthorizingCommandOutboxDispatcher) — enforces[RequireRole]and[RequirePermission]on the command's runtime type before it reaches the outbox. - DI composition helpers that wire Mediator, Outbox, Identity, and EFCore into a hosted app.
- Configuration providers and option binders used by the worker stack.
Dependencies
Transitively depends on Stratara.Contracts, Stratara.EventSourcing.EntityFrameworkCore, Stratara.Mediator, Stratara.Outbox.RabbitMQ, Stratara.Sessions, Stratara.Shared.
Behavioural notes
AddSecurity() — IKeyStore registration (since 3.0.11)
AddSecurity() registers Stratara's security stack including the IKeyStore abstraction. The default is a TryAddSingleton<IKeyStore, DummyKeyStore> fallback — but DummyKeyStore since 3.0.11 throws InvalidOperationException in any environment other than Development (whitelist guard to prevent production data exposure from the demo encryption key). Hosts on Staging, QA, UAT, Preview, or any custom environment must register a real IKeyStore implementation before calling AddSecurity():
// Recommended composition root
if (builder.Environment.IsDevelopment())
{
builder.Services.AddSecurity(); // DummyKeyStore fallback is fine
}
else
{
// The production key store Stratara ships (Stratara.Security): KEK-wrapped, versioned
// per-scope DEKs. Register it before AddSecurity() so it wins the TryAdd race.
builder.Services.AddStrataraFileKeyStore(builder.Configuration);
builder.Services.AddSecurity();
}
Stratara ships one production IKeyStore — EnvelopeFileKeyStore, via AddStrataraFileKeyStore.
There is no built-in Azure Key Vault / AWS KMS / HSM store; if you need one, implement IKeyStore
against your provider and register it in place of the file store. Implement ListScopesAsync as
well: an erasure asks the key store for every key naming the subject, and a store that cannot list
leaves it with only the keys the directory names.
KeyStoreStartupProbe logs a Warning (event id LogEvents.KeyManagement.DummyKeyStoreActive = 112_001) at host start when the resolved IKeyStore is DummyKeyStore — even in Development — so an accidental dependency on the dummy is loud rather than silent.
Why the change: Before 3.0.11 the guard only blocked IsProduction(). Hosts in any other environment silently encrypted with the world-known constant pass-phrase "StrataraTestKey" baked into the shipping NuGet — a Staging or QA copy of production data could be decrypted by anyone reading the source. The whitelist guard makes this configuration crash-fast at host build instead of allowing silent data exposure.
AddCaching() — Redis registration
AddCaching() used to delegate to builder.AddRedisClient("redis") from Aspire.StackExchange.Redis. After the Aspire-wrapper removal it registers IConnectionMultiplexer directly via ConnectionMultiplexer.Connect(...) from StackExchange.Redis. The method signature is unchanged, but the Aspire-only side-effects are gone:
- No automatic Redis health check. Add one explicitly with
AddHealthChecks().AddRedis(connectionString)(fromAspNetCore.HealthChecks.Redis) if your host exposes/healthand you want Redis covered. - No automatic OpenTelemetry Redis instrumentation. Add
OpenTelemetry.Instrumentation.StackExchangeRedisand.AddRedisInstrumentation()to yourTracerProviderBuilderif you want Redis spans in your traces.
The connection-string lookup (ConnectionStrings:redis in configuration) is identical to the pre-cleanup behaviour.

Stratara.EventSourcing.WorkerDefaults
Worker-host wiring composites for the Stratara event-sourced stack. IHostApplicationBuilder extensions (AddBackendServices, AddCommandWorkerServices, AddHeavyCommandWorkerServices, AddEventProjectionWorkerServices, AddEventStreamHashWorkerServices, AddSagaWorkerServices, AddOutboxWorkerServices, and AddCommandServices, AddEventProjectionServices and AddSagaServices without the bus-fed workers) bundle the per-concern DI calls so each worker host opts in with one line. |

|
Stratara.Testing.EntityFrameworkCore
Spin up the real Stratara event-sourcing write stack (EventSource, aggregation, snapshots, the EF Core write store) against a shared in-memory SQLite database in one call — production code paths, no Postgres, no Docker. Builds on Stratara.Testing's in-memory doubles. |

A release about a flag that cost too much. Every host sharing the replay coordination state over Redis
asked Redis, with a blocking round trip on the calling thread, whether a replay was active — and the
Orleans execution model asked on every hot path, eight to ten times per command on a host with three
projections, inside grain turns. On a two-core host that was enough to starve the thread pool and time
the Redis connection out, surfacing as failed catch-ups, lagging read models and failed grain
registrations although no replay ever ran. The answer now comes from memory. No migration is needed;
one optional setting is new.
### Fixed
- **No path waits on Redis to learn whether a replay is active.** The Redis-backed replay state answers
`IsReplayActive` from a field. A change made in the host itself is seen there at once; a change made
elsewhere — a replay that began or ended in another host, or a marking that lapsed — is announced over
a channel beside the replay-request channel and seen within its latency, and every host re-reads the
marking every `ProjectionReplay:RefreshSeconds` regardless, as the safety net for a lost announcement.
The Orleans execution model's command dispatcher, bundle dispatcher, store readers and drain, and the
bus dispatchers, make no Redis call for it any more. Nothing changes for a host without Redis, whose
state was in process already, nor for a host that registers its own `IProjectionReplayState`.
### Added
- **`ProjectionReplayOptions.RefreshSeconds`** (default 5), read from the `ProjectionReplay` section
like the lease. It bounds how long a host answers from a replay marking that changed elsewhere where the
announcement was lost. Refused when the host starts at zero or below, and at or above
`LeaseSeconds`, with an `OptionsValidationException` naming `ProjectionReplay:RefreshSeconds`.
- **Log events `104_015` to `104_018`.** A host that cannot refresh the replay marking from Redis says
so once at Warning (`104_015`) and keeps its last answer; `104_016` at Information says it reads the
marking again. A host that cannot subscribe to the marking's announcements says so once at Warning
(`104_017`), sees a change on the refresh period only, and `104_018` says it is subscribed again.
### Changed
- **A host that cannot reach Redis keeps its last answer about the replay.** Before, every dispatch and
every catch-up on such a host failed with the connection's exception. Now they proceed on what the host
last learned — initially that no replay is active — and the loss is logged once. The replay stays
correct regardless: on the Orleans execution model the readers are paused by the rebuild and the
replay themselves, and apply the store from the beginning once more when the replay ends.
- **Rolling upgrade.** A host on a release before this one announces nothing when it starts or ends a
replay, so a host on this release sees that replay at the refresh period rather than at once. The
marking, its key and its lease are unchanged, so the two releases share one replay state.
