Declarative PHP 8 attributes on the classes you already have. [Event Sourcing](https://ecotone.tech/event-sourcing) (PDO-backed Event Store) ------------------------------------------------------------------------------ [](#event-sourcing-pdo-backed-event-store) Full Event Sourcing support for Ecotone, backed by your relational database via PDO. Event-sourced aggregates, projections, upcasting, and replay — all driven by attributes on your existing classes. - **Event-sourced aggregates** via `#[EventSourcingAggregate]` — one attribute flips state-stored to event-sourced - **Event-sourced sagas** via `#[EventSourcingSaga]` — [durable workflows](https://ecotone.tech/durable-workflows) where every state transition is a replayable event in your database - **Projections** via `#[Projection]` — catch-up, reset, partition, and streaming variants - **Event versioning and upcasting** — evolve your event schema without rewriting history - **Streaming Projections** — process events in real-time with Message Broker transport - **PostgreSQL and MySQL** supported out of the box Same testing story as the rest of Ecotone: spin up the event store in memory with `EcotoneLite::bootstrapFlowTesting`, replay events into your projections, and assert on results — no external infrastructure required.
