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

1.10.3 - 2023-09-05

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.

1.9.17 - 2023-07-03

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.

1.8.3 - 2023-06-02

Fixed

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

1.7.23 - 2023-05-31

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.

1.6.8 - 2022-07-06

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.

1.5.3 - 2022-07-05

Added

  • Introduced configuration of custom json converters (#23)

1.4.5 - 2022-03-18

Added

  • Support for Token Credentials with Comos DB using UseCredentials methods on options class.
