Add and manage a destination in an eventstream

Once you have created an eventstream in Microsoft Fabric, you can route data to different destinations. The types of destinations that you can add to your eventstream are KQL Database, Lakehouse, Custom App and Reflex. See the Supported destinations section for details.

Prerequisites

Before you start, you must complete the following prerequisites:

• Get access to a premium workspace with Contributor or above permissions where your eventstream is located.
• For a destination of type KQL database, lakehouse, or Reflex, get access to a premium workspace with Contributor or above permissions where your destination is located.

Supported destinations

The following destinations are supported by Fabric event streams. Use links in the table to navigate to articles that provide more details about adding specific destinations.

Destinations	Description
Custom app	With this destination, you can easily route your real-time events to a custom application. It allows you to connect your own applications to the eventstream and consume the event data in real time. It's useful when you want to egress real-time data to an external system living outside Microsoft Fabric.
KQL database	This destination enables you to ingest your real-time event data into a KQL database, where you can use the powerful Kusto Query Language (KQL) to query and analyze the data. With the data in the Kusto database, you can gain deeper insights into your event data and create rich reports and dashboards. You can choose between two ingestion modes: Direct ingestion and Event processing before ingestion.
Lakehouse	This destination provides you with the ability to transform your real-time events prior to ingestion into your lakehouse. Real-time events convert into Delta Lake format and then stored in the designated lakehouse tables. It helps with your data warehousing scenario. To learn more about how to use the event processor for real-time data processing, see Process event data with event processor editor.
Reflex	This destination allows you to directly connect your real-time event data to a Reflex. Reflex is a type of intelligent agent that contains all the information necessary to connect to data, monitor for conditions, and act. When the data reaches certain thresholds or matches other patterns, Reflex automatically takes appropriate action such as alerting users or kicking off Power Automate workflows.

Note

• The maximum number of sources and destinations for one eventstream is 11.
• Event data retention in an eventstream is 1 day, with the potential to extend it and make it configurable in the future.

Manage a destination

Edit/remove: You can edit or remove an eventstream destination either through the navigation pane or canvas.

When you select Edit, the edit pane opens in the right side of the main editor. You can modify the configuration as you wish, including the event transformation logic through the event processor editor.
