Term	Kind	Topic	What it is
Event Store	tool	Event Sourcing	An append-only store of domain events organised into per-entity streams, serving as the system of record rather than as a log beside it.
Event Upcasting	pattern	Event Sourcing	Transforming an old event's stored form into the current shape as it is read, so historical events remain replayable after the schema changes.
Snapshotting	pattern	Event Sourcing	Periodically storing an aggregate's computed state so it can be loaded without replaying its entire event history.
