Helper IIIPower BI Dataflow: This step would be evaluated outside the data source
When I read more, it has to do with Query folding and it seems that the icon tells me there is No Folding happening. I wanted to know if any of my data gets exposed in this case and if this is a possible security problem?
Nothing gets exposed, because the processing is happening in the Power BI Service rather than in the data source. Depending on how fast your source is this may have a performance impact either way.
