Implements robust event sourcing patterns, projections, and event versioning within the Ecotone framework.
This skill provides specialized guidance for implementing Event Sourcing in PHP using the Ecotone framework. It enables developers to build event-sourced aggregates, create high-performance projections with partitioning and streaming, manage event stores, and handle schema evolution through versioning and upcasting. By shifting from state-based to event-based persistence, it helps maintain a complete audit trail and scale complex domain logic with ease while ensuring consistency across distributed systems.

01Partitioned projections for efficient per-aggregate instance tracking
02Native Event Store API for stream management, appending, and replaying events
03Advanced ProjectionV2 supporting synchronous, polling, and streaming modes
04Event versioning and upcasting for seamless schema evolution
