Drillthrough Paginated Reports

I'm helping a client convert a few SSRS reports from SharePoint to Power BI Premium Per User (PPU). SSRS is of course near and dear to my heart because of all the work I've done around it circa 2004-2010 (yep, it's been that long), books, MVP awards, etc. Since its humble beginnings, SSRS have had a solid architecture that excelled in extensibility. You'd be hardly…

Chasing SSAS Connection Timeouts

Suppose you have a Tabular model and you send a massive DAX query to it that could run for hours, such as to calculate many measures (in our case hundreds) for each customer overnight so that you can cache the results and delight the user with super-fast lookups. This issue could also apply to Multidimensional although in this case Tabular was used. The server times…

Azure Data Factory is Getting Better All the Time

Three years ago, I wrote that it would probably take a decade for to mature and close the gap with SSIS. To its credit thought, while it's still lagging in the area of extensibility, ADF added features that we don't have in SSIS so I'm developing a taste for it: Schema drift – Suppose you want to automatically stage new columns as they added to…

Interactive Excel Pivots in Power BI

A long-standing limitation of Power BI has been that Excel pivot reports connected to external Analysis Services models can't be interacted with when uploaded to Power BI Service. You get the cached pivot report but any attempt to interact with the report online (that is in Excel Online), such as to change a slicer or filter, would result in an error complaining that the connection…

Cloud Inhibitors

In a previous blog, I said I consider it a travesty when a vendor's cloud offering prohibits direct access to the data in its native storage, which is typically a relational database, and therefore a perfect store for data analytics and integration, such as to run real-time analytics or export the data to load a data mart. There is nothing simpler than connecting to a…

Synapse Serverless: The Good, The Bad, and The Ugly

When you a provision a Synapse workspace, you get a serverless endpoint for free (or almost free). This endpoint represents Synapse Serverless: a query service for ad-hoc exploration of data in CVS, Parquet, and JSON files stored in Azure Data Lake. The Good Being able to query files using SQL is great. Some of you might remember the U-SQL language that was introduced a few…

I switched an enterprise client P2 node to Gen 2 a few months ago and here are the top benefits we observed: Lower CPU utilization The Gen1 P2 node was under CPU pressure so the client was…

Power BI Aggregations: Limitations and Workarounds

Power BI aggregations are meant to speed up queries to large DirectQuery tables, as a DBA would create summarized tables to speed up queries to large tables. The most appealing aspect of telling Power BI about these aggregations is that Power BI will automatically redirect the query to the aggregation cache if it determines that its dimensionality matches the dimensionality of the aggregated table, as…
