Introduction to Fauna Event Streaming

Discover how Fauna’s Event Streaming transforms real-time data integration, enabling dynamic push and pull updates for scalable application development.

Instantaneous Data Synchronization

Fauna's Event Streaming ensures that data across client applications and services is updated in real-time, as changes occur.


This eliminates the need for constant polling of the database for updates, reducing latency and enhancing the user experience in applications such as live dashboards in SaaS apps, eCommerce sites for inventory management, or real-time collaboration tools.

“Fauna is the reason we are still in business. There is not enough good stuff I can say about the folks over there.” Read case study

Secure Notifications with Granular Control

With Fauna's Event Streaming, developers can precisely define the scope of data changes they subscribe to using Fauna Query Language (FQL). Combined with Fauna's built-in security features, such as attribute-based access control (ABAC), event streams can be securely tailored to specific user roles or business logic, ensuring that sensitive data is only transmitted to authorized parties.

Export Data from Fauna to Downstream Systems

Unlock the full potential of change data capture (CDC) by ingesting real-time push updates as changes occur, or pull update history on demand to synchronize data across your systems. This dual capability enables robust data operations suitable for analytics, compliance, and migration use cases.

Efficient and Scalable Architectures

By leveraging Fauna's native global distribution and serverless architecture via its Distributed Transaction Engine, Event Streaming allows developers to build highly scalable real-time applications without worrying about infrastructure.


Event Streaming integrates seamlessly with serverless functions and other microservices, enabling efficient, event-driven architectures that automatically scale with your application's needs.

Capabilities

Comprehensive Event Notifications

Developers can return an entire document within a notification, ensuring that any application subscribed to a stream can receive complete, up-to-date information about changes, enabling immediate action or updates without needing to query the database again. This significantly simplifies data management and synchronization across services.

Flexible Subscription Models

Fauna offers the flexibility to subscribe to all events within a collection or to a targeted subset of document changes based on a specific FQL query. This versatility allows developers to tailor event subscriptions precisely to their application's needs, whether monitoring a broad set of changes or focusing on highly specific data alterations.

READ THE DOCS

Change Feeds

Generate detailed, chronological record of data changes, allowing applications to pull updates as needed. Change Feeds supports both "Latest Version" mode for current state snapshots, and "All Versions" mode for a complete history of changes. This enables applications to quickly adapt by either pulling the most recent updates, or accessing a comprehensive historical record of changes as needed.

READ THE DOCS

Snapshot on Stream Start

Upon initiating a stream, Fauna provides the capability to get a snapshot of the documents at the moment the stream is started. This feature is invaluable for applications that require an initial state before listening for incremental updates, such as loading the initial dataset for a UI component before applying real-time changes.

READ THE DOCS

Snapshot Exports

Export a complete, transactionally consistent snapshot of your database to seed analytics platforms, vector databases, and search engines. Snapshots are encrypted, compressed, and include all documents, schema, and configurations.

Use Cases

Maintaining Live Application State

Many applications mandate real-time updates to ensure that the application's UI reflects the current state of the backend without manual refreshes – critical for dynamic environments where data changes frequently and needs to be immediately visible to users.


Examples include inventory updates in eCommerce/Retail apps, leaderboard updates in multiplayer gaming, or real-time analytics and dashboards in SaaS apps

Collaborative Applications

Event Streaming facilitates direct communication between various parties through shared documents or data collections. Examples include real-time messaging in chat applications or real-time updates in document editing, social apps, or project management tools.

Event-Driven Applications

Event Streaming allows components of an architecture to subscribe to specific events or data changes and react accordingly, without needing to know the source of the changes. This is useful for event-driven architectures, where microservices subscribe to relevant events from other services to trigger workflows or updates.
