TALL DATA Gave Me 5x Faster Power BI Performance #shorts #data #powerbi #performance

Here's how I achieved 5x faster Power BI performance.
One of the important steps in data cleaning is data reshaping.One big flat table is not a good solution. So how to change it?
first, Split columns (for example If you have a full name, split it into first and last name columns).
then Merge and append queries to combine data sources.
The last thing - Unpivot wide tables into tall formats.
The “tall data” works better in Power BI, because of nature how the storage engine works and it makes tall, narrow tables with many rows and few columns super-efficient for processing data.
