VertiPaq Analyzer for Analysis Services #ssas #tabular #powerpivot #powerbi

During the writing of The Definitive Guide to DAX I wanted a simple way to analyze the content and distribution of data compressed in the VertiPaq engine, used by Analysis Services Tabular, Power Pivot and Power BI models. I always relied on BISM Memory Report (thanks Kasper!), but when you focus on a single database there are a number of details available in other data management views (DMVs) other than the one used by BISM Memory Report.

I created VertiPaq Analyzer, which is a Power Pivot data model that collects data by these other DMVs and shows them in pivot tables that provide you information about compression, size of data and related structures (such as relationships and hierarchies), and column selectivity (very important to understand how to optimize DAX queries.

You can download the workbook here, and read the article that describes all the metrics used.
