Horizontal Fusion tested?

[ML222]

Hi,

I am reposting this question from another thread regarding horizontal fusion that was closed.

Has anyone been able to test this feature successfully yet?

I have tested some queries in DAX Studio while connected to a dataset with Horizontal Fusion disabled. Then enabled the feature, restarted Power BI, connected to the dataset and run the same query.

Time elasped is the same.

Number of queries sent off is the same.

Could be the queries I am running but just want to double check that someone has actually had success in testing this feature?

My dataset is connected via DirectQuery to SQL Server.

We have Premium P1 SKU - I haven't heard any feedback on improved performance either.

Alberto at SQLBI has just put up a video on Youtube explaining it using DAX Studio to show how it can help.

Hi @ML222 ,

As far as I know, Horizontal Fusion should be a preview feature. There may be some drawbacks in this function.

I think you may submit your feedback at the end of below blog. If there are many users facing the same issues, Power BI Team will fix these issues in future updates.
