Release 1.14.11

Added

• Implement IEventStoreManagementClient.DeleteStreamAsync using the newly released DeleteAllItemsByPartitionKeyStreamAsync method in the Cosmos SDK.
• Extend CommandContext with the current StreamVersion of the stream.

Release 1.13.3

Added

• Introduce instrumentation support for Open Telemetry.

builder
    .Services
    .AddOpenTelemetry()
    .WithMetrics(metrics =>
    {
        metrics
            .AddAspNetCoreInstrumentation()
            .AddHttpClientInstrumentation()
            .AddRuntimeInstrumentation();
    })
    .WithTracing(tracing =>
    {
        if (builder.Environment.IsDevelopment())
        {
            // We want to view all traces in development
            tracing.SetSampler(new AlwaysOnSampler());
        }

        tracing
            .AddAspNetCoreInstrumentation()
            .AddHttpClientInstrumentation()
            .AddSource(EventStoreDiagnostics.SourceName); // enable trace telemetry from event store and cqrs.
    });

Release 1.12.6

Fixed

• RequiredVersion was not respected when command handler was consuming events.

Release 1.11.3

• Add missing methods in IProjectionBuilder to enable configuration of projection subscription start options.

Release 1.10.3

Added

• Support for controlling the start time from where a new event subscription or projection should start receiving changes. By default, it will start from the beginning of time to preserve backwards compatibility.

services.AddEventStore(builder =>
{
    builder.UseCosmosDb();
    builder.UseEvents(c => c.FromAssembly<MyEvent>());
    builder.UseCQRS(c =>
    {
        c.AddProjectionJob<MyProjection>(
            "super-projection-name",
            c => c.WithProjectionStartsFrom(
                SubscriptionStartOptions.FromBegining)); // setting the start time
    });
});

• Controlling projection PollingInterval and MaxItems received on ever iteration.

Release 1.9.17

Added

• Introduced options to provide events async when testing commands using ICommandGiven, ICommandWhen and ICommandThen.
• Introduce hard limits to the number of events the system can accept per operation.
  • A maximum of 10 events per command context (CQRS)
  • A maximum of 50 events per stream batch (Event Store)

Fixed

• Fixed issue where adding two or more projections with the same class name would override their configurations resulting in the "dead" projections.

Release 1.8.3

Fixed

• Removed writing to stream-index when a new stream is created.

Release 1.7.23

Added

• Pipeline for controlling event data convertion IEventDataConverter
• Added custom event data converters to be configured using EventStoreOptions. This will enable scenarioes such as converting from one version of an event to another.
• Unknown or invalid events can now be observed through the IConsumeEvent<T> and IConsumeEventAsync<T> by using well known types FaultedEvent and UnknownEvent.
• Introduced new interfaces IConsumeAnyEvent and IConsumeAnyEventAsync for consuming any event without specifying it type.
• Command processor is now registered as singleton, eliminating the need for using ICommandProcessorFactory.
• Optionally configure cosmos client to accept any server certificate when using emulator.

Fixed

• Raise condition when 2 command processors tries to add the first event to the same stream concurrently.
• Rerunning command now create a new instance of the command processor to clear out any previous state it might contain.

Removed

• Setting ConfigurationString when configuring event store options.
• EventId has been removed from Metadata.

Release 1.6.8

Added

• Exception delegate for receiving any exception douing a stream subscription.
• Throws ArgumentException when a projection is missing a ProjectionFilter.
• BREAKING - IProjection now require you to implement FailedAsync(Exception exception, CancellationToken cancellationToken) and instruct the framework on how to proceed when encountering an exception.
• Convenience extension methods to CommandContext.

Release 1.5.3

Added

• Introduced configuration of custom json converters (#23)
