How to run Parallel Power Queries and Append them?

[Anonymous]

Hi, 
I am creating a report which uses Kusto Query Language which makes a Direct Query to Kusto Tables. Now, I am doing summarization tasks on Telemetry Data from the last 30 days and the visuals load very slowly because the computation takes too much time as the Data is humungous. So, I wanted to do parallel computation i.e. I split the Time Range into three different sets of 10 days each made 3 different queries and then appended the 1st and 2nd query into the third. But, I received an error message saying that this operation is not allowed in Direct Query. Can you tell me what other ways can be employed to perform a parallel compute? If not, how can I reduce my Query Execution time?

Thanks

If this were import mode instead of appending the queries in Power Query you would load them all and then UNION them in DAX.  But that approach won't work for live connections (and it would incur a large storage cost).
