Real-Time Data Streaming
VortexDB allows you to subscribe to changes in your data in real-time. This is useful for building reactive applications that need to display up-to-date information.
Change Feeds
VortexDB provides a change feed API that allows you to subscribe to changes in your data. You can use this API to build real-time applications, such as chat applications and live dashboards.
How Change Feeds Work
| Event Type | Payload | Latency |
|---|---|---|
| Insert | New document | <5ms |
| Update | Delta changes | <5ms |
| Delete | Document ID | <5ms |
Change feeds capture all data modifications (inserts, updates, deletes) as a continuous stream of events. Applications can subscribe to these events and react to them in real-time.
Use Cases for Change Feeds
- Real-time Analytics: Analyze data as it changes to gain immediate insights.
- Event Sourcing: Build event-driven architectures where data changes are treated as events.
- Data Synchronization: Keep multiple systems synchronized with the latest data.
- Auditing and Compliance: Maintain a complete history of all data modifications.
WebSocket Integration
VortexDB includes a built-in WebSocket server that makes it easy to stream data to your client-side applications.
Benefits of WebSocket Integration
- Low Latency: Real-time data updates without polling.
- Bidirectional Communication: Allows both server-to-client and client-to-server communication.
- Reduced Overhead: More efficient than traditional HTTP requests for continuous data streams.
Example Use Cases
- Live Dashboards: Display real-time metrics and visualizations.
- Collaborative Applications: Enable multiple users to work on the same data simultaneously.
- Gaming: Provide real-time updates for game states and player actions.
