❓ FAQ

Do I need event sourcing for every aggregate?
No. Use state‑based repositories where audit trails/replay aren’t needed.

Can I mix event‑sourced and state‑based aggregates?
Yes. Configure repositories per aggregate class.

How do I rename an event?
Keep data stable by using event aliases. If the shape changes, bump a version and add an upcaster.

How do I handle huge aggregates?
Use snapshots and choose an appropriate fetch strategy (chunked/streaming).

Is replay safe?
Only listeners implementing Projector are invoked during replay. Side‑effecting listeners are skipped.
