scaffold-multi-stream-projection

By defining a Marten MultiStreamProjection class, you can aggregate events from multiple streams into a single read model. This approach targets event-sourced .NET services using Marten to build comprehensive cross-stream dashboards.

A Marten MultiStreamProjection is used to consume events from multiple distinct streams and aggregate them into a single, comprehensive read model. This simplifies cross-stream analytics and dashboard creation for event-sourced .NET services.

You register a multi-stream projection in Marten configuration by adding it via MartenConfigurationExtensions. The projection class must be defined in your project, and you should add appropriate indexes to the read model for efficient querying.

Yes, you can use multi-stream projections to build dashboards from event sourcing by consuming several event streams. For example, you can aggregate total sales, user activity, and inventory status events into one unified read model.

Yes, Marten multi-stream projection requires adding appropriate indexes to the read model for efficient querying. This ensures that aggregated data from multiple streams remains performant when queried for dashboards and analytics.
