Real-Time Intelligence tutorial part 2: Get data in the Real-Time hub

Note

This tutorial is part of a series. For the previous section, see: Tutorial part 1: Create resources.

In this part of the tutorial, you browse the Real-Time hub, create an event stream, transform events, and create a destination to send the transformed events to a KQL database.

Create an event stream

1. From the navigation bar, select Real-Time hub.

2. Select + Add source.

   

3. The Add source pane opens. Select Sample data.

Sample data

1. In Source name, enter TutorialSource.
2. In Sample data select Bicycles (Reflex compatible).

Stream details

1. Edit the Eventstream name by selecting the pencil icon and entering TutorialEventstream.
2. Select Next.

Review and create

1. Review the event stream details and select Create source.

   A new event stream named TutorialEventstream is created.

Transform events

1. Select Open Eventstream from the notification that appears after creating the event stream, or browse to the event stream from the Real-time hub and select Open Eventstream.

2. From the menu ribbon, select Edit. The authoring canvas, which is the center section, turns yellow and becomes active for changes.

3. In the event stream authoring canvas, select the down arrow on the Transform events or add destination tile.

4. Select Manage fields. The tile is renamed to Manage_fields.

5. Select the pencil icon on the Manage_fields tile.

6. In the Manage fields pane, do the following actions:

   The TutorialTransform tile now displays but with an error, because the destination isn't set.

Create a destination

1. Hover over the right edge of the TutorialTransform tile and select the green plus icon.

2. Select Destinations > Eventhouse.

   A new tile is created entitled Eventhouse.

3. Select the pencil icon on the Eventhouse tile.

   Field	Value
   Destination name	TutorialDestination
   Workspace	Select the workspace in which you created your resources.
   Eventhouse	Tutorial
   KQL Database	Tutorial
   Destination table	Create new - enter TutorialTable as table name
   Input data format	Json

5. Ensure that the box Activate ingestion after adding the data is checked.

6. Select Save.

The event stream is now set up to transform events and send them to a KQL database.
