What is a "snapshot" used for in an event-sourced system with a very long-lived stream (many thousands of events)?
What is a common trade-off consideration when adopting event sourcing for an application, compared to a traditional CRUD model that only stores current state?
What is the general relationship between an event's "type" (like `OrderPlaced` or `PaymentReceived`) and how consumers/projections process a stream?
What is a key benefit of being able to derive an entity's current state by replaying its full event history, rather than only storing the latest state directly?
How does event sourcing commonly relate to the CQRS (Command Query Responsibility Segregation) pattern?
What is a reasonable general criterion for deciding whether event sourcing (and a tool like EventStore) is a good architectural fit for a given application?
Why might versioning event schemas (handling the fact that an event's shape might need to change over an application's lifetime) be a genuinely tricky problem in a long-lived event-sourced system?
What is EventStore (EventStoreDB)?
Why might rebuilding a projection from scratch (replaying the entire event history) be a valuable capability that event sourcing enables, compared to a system that only stores current state?
What is a "stream" in EventStore's data model?
Why does careful "event modeling" (deciding what events to record and their exact shape) matter significantly in an event-sourced system's design?
Why might a team choose EventStore specifically (rather than modeling event sourcing manually on top of a general-purpose database) for an event-sourced application?
