Purview EventSourcing Wiki

Purview EventSourcing is a .NET event sourcing framework built around provider-agnostic store facades, source-generated aggregates, and multi-aggregate transaction coordination.

Key ideas

• Use IEventStore for create/get/save/delete flows.
• Use IQueryableEventStore for query/list/count flows.
• Prefer the non-generic facades in application code; the sample app demonstrates that usage style throughout.
• Use IEventStoreTransactionFactory when a workflow changes multiple aggregates together.
• Pair an event stream store with a queryable snapshot store when you need filtering, paging, or projection-style reads.
