Query Optimization

[yashwant101]

Hi all,

I have created  report where I have different time buckets and columns for fla on those time buckets. So when I am calculating the metric I am using below formula:

switch(true(),selectedvalue('Time Period'[time_period]="LTD", calculate(<formula>, [ltd_flg]=1),.....)

It is making my matrix visual very very slow. Please let me know of a way to optimize it.

Regards,

Yashwant

Hi @yashwant101 ,

You may try pre-create calculated columns or measures that don't rely on the context of the visual but are instead pre-computed as part of your model. 

And if possible, you can introduce variables to store intermediate results. This can make your formula more efficient by calculating values once and reusing them, rather than recalculating them multiple times.

Also try reviewing Data Model and Relationships. This includes reviewing table relationships, ensuring appropriate indexing, and reducing the unnecessary data loading for large datasets.
