Stratara.ServiceDefaults

Derived. The behaviour described here is specified under openspec/specs/. Those specifications are the source; this page explains and illustrates them.

Cross-host observability defaults for the Stratara stack. Reference from every host (API, worker) to get OpenTelemetry + Serilog wired up with sensible defaults.

What's in the box

Extension Purpose
ConfigureOpenTelemetry Logging + metrics + tracing with HTTP, EF Core, RabbitMQ, runtime instrumentation; OTLP exporter wired up automatically when OTEL_EXPORTER_OTLP_ENDPOINT is set. Accepts optional MeterProviderBuilder / TracerProviderBuilder callbacks for host-specific extras.
ConfigureSerilog Structured logging with destructuring attributes, async console sink, OTLP sink (gRPC or HTTP/Protobuf based on OTEL_EXPORTER_OTLP_PROTOCOL), dev-mode log cleanup at {Path.GetTempPath()}/stratara-logs/{service-name}.log — the OS temp directory, so not literally /tmp on Windows or macOS.
ConfigureSerilogBootstrapLogger Sets up Log.Logger as a bootstrap logger before the host is built, so early-startup errors surface to the console.

Quick start

builder.ConfigureOpenTelemetry();
builder.ConfigureSerilog();

It deletes your development log file on start-up

In the Development environment only, configuring Serilog deletes the current log file before opening it: %TEMP%/stratara-logs/{OTEL_SERVICE_NAME}.log, where the service name falls back to Unknown when OTEL_SERVICE_NAME is unset. The intent is a clean file per debugging session rather than one that grows across dozens of restarts.

Two consequences worth knowing before they cost you an hour:

  • A crash you wanted to read is gone the moment you restart to reproduce it. Copy the file before restarting, or point the sink elsewhere for that session.
  • Two development services with no OTEL_SERVICE_NAME share Unknown.log and delete each other's. Set the variable per service.

Outside Development nothing is deleted.

Sibling packages

  • Stratara.EventSourcing.WorkerDefaults — one-stop AddBackendServices / AddXxxWorkerServices composites that wire the framework's mediator + outbox + projections + sagas stack.
  • Stratara.ServiceDefaults.AspNetCore — ASP.NET-specific extras: AddDefaultHealthChecks + MapDefaultEndpoints (/health, /alive) and ASP.NET request OTel instrumentation.

Dependencies

  • Stratara.Shared — diagnostics base (ApplicationDiagnostics.Activity.SourceName).
  • OpenTelemetry runtime + exporter packages.
  • Serilog sinks (Console, File, Async, OpenTelemetry).
  • Destructurama.Attributed for destructuring conventions.
  • Microsoft.Extensions.Http.Resilience + Microsoft.Extensions.ServiceDiscovery.

Prerelease dependencies. This package transitively pulls in two prerelease OpenTelemetry instrumentation packages that have no stable release yet: OpenTelemetry.Instrumentation.EntityFrameworkCore (beta) and RabbitMQ.Client.OpenTelemetry (RC). Both ride the stable OpenTelemetry 1.15.x core. NU5104 is suppressed in this csproj with that justification — consumers inherit the prerelease deps transitively. We will swap to GA as soon as the vendors ship stable.

Correctness fixes for the Orleans execution model ahead of production use. Recorded commands can no longer
reach a bus drain, a durable timer fires once however long its handler runs, and heavy commands are
specified as the exception to the one-writer-per-aggregate promise they always were. The execution-model
reset removes only the host's own checkpoints, and three store-level fixes land for the partition
counter, its backfill and a checkpoint's first write. No schema change; **stop every bus outbox worker
before upgrading hosts that record commands through the execution model**, and register
`AddStrataraIntentStore` on the silos that run the drain.

### Changed

- **Orleans: the execution-model reset removes only the checkpoints of the host's own projections and
 sagas.** It removed every checkpoint in the read store, so a reset in one deployment made another
 deployment sharing the read store rebuild its projections unasked. The reset now removes the
 checkpoints of the projections and sagas registered in the composition it is resolved from, and the
 report counts only those. A checkpoint of a projection the host no longer registers stays; nothing
 reads it. Resolve the reset from the host's own composition — one that registers no store reader
 removes no checkpoint.
- **The documentation states when a read store can be shared.** Checkpoints are keyed by consumer, not
 by deployment: deployments sharing a read store need distinct projection names, and at most one of
 them runs `AddStrataraSagaGrains`.
- **Orleans: heavy commands are specified as running outside their aggregate's turn and order.** They
 always ran in their own bounded pool beside the aggregate's other commands; the specification promised
 otherwise. Their hand-over no longer holds the per-aggregate send order either: a command dispatched after
 a heavy command for the same aggregate no longer waits for it, and two due heavy commands on one aggregate
 no longer hold up the drain's resume pass. Where a heavy command and another command on the same aggregate
 both append, the store's version check refuses the later one, which is resumed like any failing command.
- **Orleans: a recorded command is stored under a kind of its own.** No bus outbox drain reads it any more.
 Commands recorded under 4.1.0 are still resumed; stop every bus outbox worker before upgrading hosts that
 record commands.

### Fixed

- **Orleans: the outbox drain no longer publishes recorded commands to the bus.** It chose between resuming
 recorded commands and publishing stored commands by whether the execution model's dispatcher was
 registered on its own silo, and the migration guide registers the dispatcher on the API host and the drain
 on the silos. Such a silo handed every recorded command — kept ones included — to the bus: commands ran
 twice, kept commands came back, the attempt bound did not hold. The drain now resumes recorded commands
 wherever an intent store is registered and warns (`117_111`) where recorded commands exist but none is.
 Register `AddStrataraIntentStore` on the silos that run the drain.
- **Orleans: a durable timer fires once however long its handler runs.** A handler that outlasted the
 reminder call's response timeout was started again by the next tick. A tick that arrives while the same
 timer's handler runs now does nothing, and a tick confirms its timer is still registered before firing.

- **Orleans: two writers of the same first checkpoint no longer fail one of them.** When an
 activation and its successor overlap during a failover, both can find no checkpoint row and both
 insert it; the one that lost to the key threw. It now updates the row the other inserted.
- **Orleans: the partition counter works on a model that does not use snake-case names.** The
 interceptor advanced the counter with SQL naming `partition_position` and its columns literally, so
 a write context mapping the counter under other names failed every append. It now goes through the
 context's model, as the native reader already did.
- **Orleans: the partition-counter backfill positions old entries in the order they were appended.**
 It ordered each partition's history by bucket first, so a projection or saga reading across
 aggregates saw the facts of one bucket before earlier facts of another. Entries are now positioned
 in sequence order, as the event-sourcing-store specification already promised. A store backfilled
 under 4.1.0 keeps the positions it was given; the backfill does not reposition entries.
