What is KurrentDB?

KurrentDB is an event-native database designed specifically to store, process, and deliver application state changes, known as events.

Each event captures a specific change in the state. Examples include when an order is placed, a payment is processed, or an item is shipped. By capturing all these incremental updates, KurrentDB captures temporal context and provides a complete audit trail of a business process.

KurrentDB offers the following features:

Feature	Description
Append-only Event Log	A durable, sequential, and immutable log that captures events in a consistent order.
Streams	Groups and indexes events to organize and speed up retrieval.
Subscriptions and Connectors	Delivers events to external systems through push or pull options.
Projection	Transforms and filters events into different streams or state.
Multiple Hosting Options	Fully managed with Kurrent Cloud, or self-managed on Linux, Windows, macOS, or with Docker.
Client SDK	Available in Python, Java, .NET, Node.js, Go, and Rust.
