Does GIT use event sourcing?
Just to clarify here: event sourcing is _not_ what Git does at all. Git stores complete snapshots of objects, not diffs [1]. Event sourcing itself is a fairly straightforward concept which the parent does sum up though – store events which describe what happened to an entity in a system rather than the resulting state.
Is Kafka used for event sourcing?
TL;DR: Kafka is not an event store; rather, it is an enabler for building event stores. For the most trivial of use cases, Kafka’s support for unbounded retention, combined with per-entity record keying, tombstones and topic compaction may be used to build a very rudimentary event store.
What does event mean in Event Sourcing pattern?
Application code sends a series of events that imperatively describe each action that has occurred on the data to the event store, where they’re persisted. Each event represents a set of changes to the data (such as AddedItemToOrder ).
How does event sourcing based business logic work?
Event sourcing-based business logic consists of loosely coupled business entities that exchange events. This makes it a lot easier to migrate from a monolithic application to a microservice architecture. It is a different and unfamiliar style of programming and so there is a learning curve.
How is Event Sourcing different from change data capture?
Event Sourcing uses its own journal as the source of truth, while Change Data Capture depends on the underlying database transaction log as the source of truth. This difference has major implications on the design and implementation of software which will be presented later in this article.
What are the benefits of Event Sourcing architecture?
Event sourcing has several benefits: It solves one of the key problems in implementing an event-driven architecture and makes it possible to reliably publish events whenever state changes. Because it persists events rather than domain objects, it mostly avoids the object‑relational impedance mismatch problem.
