The Connect data source experience, Microsoft sources page, Fabric events page, and Azure events page in Real-Time hub allow you to create streams for the supported sources. After you create these streams, you can process them, analyze them, and set alerts on them. This article explains how to process data streams using transformations supported in Fabric eventstreams.
In Real-Time hub, when you create streams to get events from the supported sources, an eventstream is created for you. You can open the parent eventstream for a stream by using one of the following ways:
-
Add source experience:
At the end of creating this stream, on the Review + connect page, you see the Open eventstream link to open the eventstream associated with the stream in an editor.
-
All data streams page:
Move the mouse over a stream whose parent is an eventstream, and select the Open link, on select ... (ellipsis), and then select Open eventstream.
-
Detail page:
From the All data streams page select a stream whose parent is an eventstream to see the stream details. From the ribbon, select Open eventstream.
After you open the eventstream in an editor, you can add transformations such as Aggregate, Expand, Filter, Group by, Manage fields, and Union, to transform or process the data streaming into Fabric, and then send the output data from transformations into supported destinations. For more information about transformations, see Supported transformation operations.

After you process data in the stream, you can send the output data to destinations supported by Fabric eventstreams.
