eventsare

Eventsare is a term used in discussions of event-centric design to describe a perspective in which events—rather than commands or direct state mutations—are the primary building blocks of a system. In this view, the system’s history is an immutable log of events, and current state is a projection derived by replaying those events in sequence. The phrase emphasizes that changes are expressed as events and that these events serve as the source of truth for downstream processing and queries.

Key characteristics include an append-only event log, ordering guarantees, and the ability to reconstruct state by replaying events from a known point. Event schemas, versioning, and idempotent projections frequently appear as design concerns, since evolving events can affect how state is derived. Practically, eventsare informs data modeling, stream processing, and service interoperability, enabling real-time analytics and comprehensive audit trails.

Relations to established concepts include event sourcing and event-driven architecture; eventsare is often used as a shorthand to stress the primacy of events in modeling. The approach can improve traceability but introduces challenges such as schema evolution, cross-service causality, and debugging complexity in replay-based systems.

Notes: The term is not universally standardized and appears primarily in theoretical and practitioner discussions rather than as a formal specification. Related topics include event sourcing, event-driven design, domain-driven design, and CQRS.
