Connecting Streaming Dataset to PowerBI Desktop
Hi all
I have created a streaming dataset inside my workspace in PowerBI Service for scraping twitter data by Power Automate, but now when I try to open PowerBI Desktop > Get Data > PowerBI Datasets > and then click on my streaming dataset I get this error:
Feedback Type:
Frown (Error)
Error Message:
Value cannot be null.
Parameter name: Data Source
Hi RexaZii93 ,
With a streaming dataset, data is also pushed into the Power BI service, with an important difference: Power BI only stores the data into a temporary cache, which quickly expires. The temporary cache is only used to display visuals, which have some transient sense of history, such as a line chart that has a time window of one hour.
With a streaming dataset, there is no underlying database, so you cannot build report visuals using the data that flows in from the stream. As such, you cannot make use of report functionality such as filtering, Power BI visuals, and other report functions.
The only way to visualize a streaming dataset is to add a tile and use the streaming dataset as a custom streaming data source. The custom streaming tiles that are based on a streaming dataset are optimized for quickly displaying real-time data. There is little latency between when the data is pushed into the Power BI service and when the visual is updated, since there's no need for the data to be entered into or read from a database.
In practice, streaming datasets and their accompanying streaming visuals are best used in situations when it is critical to minimize the latency between when data is pushed and when it is visualized. In addition, it's best practice to have the data pushed in a format that can be visualized as-is, without any additional aggregations. Examples of data that's ready as-is include temperatures, and pre-calculated averages.
