What Does Kafka Do?

Learn about the fundamentals of Kafka, event streaming, and the surrounding ecosystem. Click on an element to find out more.

Event Streaming

Create, import, share streams of events like payments, orders, and database changes in milliseconds, at scale. Store them as long as you need. Replay and reprocess historical data like a time machine.

Continuous Real-time Processing

Build lightweight, elastic applications and microservices that respond immediately to events and that scale during live operations. Process, join, and analyze streams and tables of data in real-time, 24x7.

Your Data, Everywhere

Use one platform to set data in motion across your entire enterprise. Connect systems, data centers, and clouds—all with the same trusted technology. The largest production deployments handle trillions of events per day.

Design. Build. Run.
