• Power BI Workspace Identity Authentication

    December 9, 2025 / No Comments »

    What credentials do you use to refresh your Power BI semantic models from Azure SQL SKUs, such as Azure SQL Database. Probably your credentials or a designated Entra account? Both are not ideal for a variety of reasons, including requiring a password. More advanced users might be using service principals, which are more secure but require secret renewal after a maximum of 24 months, which is a hustle. Somewhere along the way without me noticing, Microsoft added a better authentication option for refreshing Power BI semantic models: workspace identity. This option lets the Power BI workspace using its own managed identity to authenticate to the data source. And it’s available in all Power BI and Fabric SKUs! What’s not clear from the documentation is how to grant permissions to the workspace identity to read data from Azure SQL SKUs but it’s no different that granting access to the Azure Data...

  • SaaS Losers and Winners: Paylocity and Element

    November 19, 2025 / No Comments »

    “We are sailing to Philadelphia A world away from the coaly Tyne Sailing to Philadelphia To draw the line The Mason-Dixon line” “Sailing to Philadelphia”, Mark Knopfler As I’ve said in the past, I consider it a travesty when a SaaS provider disallows direct access to the data in its native storage, such as by ODBC and OLE DB providers, and force you to use file extracts or APIs (often horrible and typically designed for app integration and not DW loads). This greatly inhibits data integration scenarios, such as extracting data for data warehousing. I wrote on this subject many times, including here, here and here. Continuing on this subject, let’s consider two other vendors: Paylocity and Element. SaaS Loser: Paylocity Like Workday, Paylocity is a popular HR cloud platform. And like Workday, Paylocity doesn’t provide direct access to their database citing “security and IP concerns”. Instead, you must resort...

Instead of wandering into these traps unprepared, what if you had the Master...

  • Replicating BigQuery to Fabric

    October 3, 2025 / No Comments »

    A recent engagement required replicating some DW tables from Google BigQuery to a Fabric Lakehouse. We considered the Fabric mirroring feature (back then in private preview, now publicly available) and learned some lessons along the way: 1. 400 Error during replication configuration – Caused by attempting to use a read-only GBQ dataset that is linked to another GBQ dataset but the link was broken. 2. Internal System Error – Again caused by GBQ linked datasets which are read-only. Fabric mirroring requires GBQ change history to be enabled on tables so that it can track changes and only mirror incremental changes after first initial load. 3 (Showstopper) The two permissions that raised security red flags are bigquery.datasets.create and bigquery.jobs.create. To grant those permissions, you must assign one of these BigQuery roles: • BigQuery Admin • BigQuery Data Editor • BigQuery Data Owner • BigQuery Studio Admin • BigQuery User All these...

  • Migrating Fabric Import Semantic Models to Direct Lake (Part 2)

    August 24, 2025 / No Comments »

    I’ve previously shared my experience with migrating a Fabric imported semantic model to Direct Lake. This blog follows up with additional observations about performance. The following screenshot is taken from the Fabric Capacity Metrics app and it shows the maximum metrics over 14 days. The two enclosed items of interest are the original imported semantic model (the first item on the list) and its DL counterpart (the seventh item on the list). Memory utilization As I explained in the first part, the whole reason for taking this epic journey was to solve the out-ot-memory blowouts and constant pressure to climb the Fabric capacity ladder. With 1/5 of the user audience testing the dataset in production environment, that dataset grew to a maximum of 25 GB memory utilization which is in line with the imported model. It could have been interesting to downgrade the capacity, such as to F64, and observe...
