Help optimizing a row by row calculated column that filters on the past 30 minutes

Hello All,   I have spent all day today and yesterday trying to solve an issue I have with a calculated column a former colleague made. It is taking extremely long to run over data sets of 300-400k...

    Hi PJStevens ,

     

    Maybe you can try below formula to create calculated column:

    Summed Calculation = 
VAR CurrentDateTime = 'Table'[DateTimeKey]
VAR StartTime = CurrentDateTime - TIME(0, 30, 0)
VAR Summed = 
    CALCULATE(
        SUM('Table'[Counter Onderbreking CV]) / 4,
        FILTER(
            'Table',
            'Table'[DateTimeKey] <= CurrentDateTime &&
            'Table'[DateTimeKey] > StartTime
        )
    )
RETURN
    IF(Summed = 1, 1, 0)

    Best Regards,

Hello,

 

Thanks for the reply. This is indeed the solution I went with, unfortunately, due to the nature of the calculation, I have decided to only apply it to the past 2 months as to not overload it.


I will mark it as solved, as this is essentially the same calculation I am using, but instead of using it on the entire data set, I only use it on the past 2 months.

 

Thanks anyways for the reply.
