Power BI “Horizontal Fusion”

It’s been awhile since we had a snazzy tech term which promises amazing performance gains… (remember “Heckaton” and “Vertipaq”…),

…but here’s something to bring back the old glory days….the impressively named “Horizontal Fusion“.

Now this one seems to be an engine improvement in Power BI, specifically as to how it creates DAX queries against your source, and with noticeable performance improvements especially in DirectQuery mode. The best part is that you enable it and it works in the background.

Once that’s done you should see fewer, more efficient DAX queries generated against your sources. Apparently it even works with Snowflake.

This is the type of new feature I like, one where I don’t have to do anything….
