Add sample data as a source
Follow these steps to add a sample data source:
To create a new eventstream, select Eventstream from the Home screen. Make sure the Enhanced Capabilities (preview) option is enabled.
To add sample data source, on the get-started page, select Use sample data.
Or, if you already have a published eventstream and want to add sample data as a source, switch to Edit mode. Then select Add source in the ribbon, and select Sample data.
On the TridentStreaming_SampleData screen, enter a Source name, select the source data you want under Sample data, and then select Add.
- Bicycles: Sample bicycles data with a preset schema that includes fields such as BikepointID, Street, Neighborhood, and Latitude.
- Yellow Taxi: Sample taxi data with a preset schema that includes fields such as pickup time, drop-off time, distance, and total fee.
- Stock Market: Sample data of a stock exchange with preset schema columns such as time, symbol, price, and volume.
After you create the sample data source, you see it added to your eventstream on the canvas in Edit mode. To implement this newly added sample data, select Publish.
Once you complete these steps, the sample data is available for visualization in Live view.
