Add Fabric OneLake events to an eventstream (preview)

  • Article

This article shows you how to add Fabric OneLake event source to an eventstream.

Note

Consuming Fabric and Azure events via eventstream or Fabric Activator is not supported if the capacity region of the eventstream or Activator is in the following regions: Germany West Central, South-Central US, West US2, West US3, West India.

OneLake events allow you to subscribe to changes in files and folders in OneLake, and then react to those changes in real-time. With Fabric event streams, you can capture these OneLake events, transform them, and route them to various destinations in Fabric for further analysis. This seamless integration of OneLake events within Fabric event streams gives you greater flexibility for monitoring and analyzing activities in your OneLake.

Event types

Here are the supported OneLake events:

Event type name Description
Microsoft.Fabric.OneLake.FileCreated Raised when a file is created or replaced in OneLake.
Microsoft. Fabric.OneLake.FileDeleted Raised when a file is deleted in OneLake.
Microsoft. Fabric.OneLake.FileRenamed Raised when a file is renamed in OneLake.
Microsoft.Fabric.OneLake.FolderCreated Raised created when a folder is created in OneLake.
Microsoft. Fabric.OneLake.FolderDeleted Raised when a folder is deleted in OneLake.
Microsoft. Fabric.OneLake.FolderRenamed Raised when a folder is renamed in OneLake.

Prerequisites
