NEW SUBSTACK ARTICLE! ICYMI, I'm writing a series about Logical Data Management. In part 3, we follow Sara "the analyst" through a single Tuesday, starting with a 9:14 message and a confident "this will take 20 minutes." It does not take 20 minutes... datamozart.substack.com/p/logical-da...

Still getting your head around #MicrosoftFabric? Not sure if you should take lakehouse or warehouse path? What changes in #PowerBI workloads? Next Monday, I'll be running live online training at @oreilly.bsky.social to help you get started with the Fabric. www.oreilly.com/live-events/...

NEW SUBSTACK ARTICLE! The story I wasn't ready to tell two years ago and how AI changed that... My first article in Logical data management series is live. Why the reports became fast, while the answers are slow? And why AI made the old problem louder? datamozart.substack.com/p/logical-da...

NEW BLOG POST! Quick question for Fabric Warehouse folks: If clustering reduces CPU by 40% and I/O by 69%, but elapsed time stays the same, is it working? Yes. And the explanation is more interesting than the answer. 100M-row demo with real numbers: data-mozart.com/cluster-by-i...

When should you process data in real time, and when does batch processing make the most sense? @datamozart.bsky.social shares a clear and thorough tutorial for current (and aspiring) data engineers.

NEW SUBSTACK ARTICLE! If I had a euro every time someone asked me “should I use Warehouse or Lakehouse in #MicrosoftFabric?” - I’d have enough to fund an F64 for a month:) And, my answer has been the same for a while now: you’re asking the wrong question! datamozart.substack.com/p/same-lake-...

My 24th course at @pluralsight.bsky.social is live! "Analyze Data in Power BI with Copilot" The real skill isn't finding the Copilot button. It's knowing HOW to ask and how to verify the answer. From structured prompts to DAX queries to narrative validation. www.pluralsight.com/courses/powe...

NEW BLOG POST! A naming framework is the cheapest piece of architecture you'll ever set up in #MicrosoftFabric. It's also the most expensive one to retrofit. data-mozart.com/the-name-gam...

I asked Claude Opus 4.7 to create a thumbnail for my upcoming YouTube video (btw, it's a small teaser of what to expect soon😉).

NEW SUBSTACK ARTICLE! If you ever tried to debug a silver layer that didn't update because a notebook failed 3h ago, you know why materialized lake views matter. The promise is simple: what if your entire medallion pipeline could be a few SELECT statements? datamozart.substack.com/p/materializ...

In need of a thorough and accessible primer on data modeling? @datamozart.bsky.social presents a one-stop resource for analytics engineers.

NEW BLOG POST! Everyone keeps asking me the same question: What now for #PowerBI? With #MicrosoftFabric reshaping its identity and AI-generated dashboards challenging its visual layer, the answer isn't as comfortable as it used to be. data-mozart.com/what-now-for...

NEW BLOG POST! "Should we process our data in batches or in real-time? It's not batch vs. stream: it's "when does the answer matter?" I decided to put down my own thoughts on both approaches and how they can be unified using #MicrosoftFabric capabilities. data-mozart.com/batch-or-str...

Feedback is in for @powerbidude.bsky.social and my yesterday session at #FabCon Atlanta, and it looks like we did a decent job (or at least 68 attendees who provided feedback agree with that)😉 Thank you, everyone, for spending your time to provide valuable feedback, very much appreciated.

Getting ready for Day 2 of #FabCon Atlanta and just learned that my tomorrow's session "The ultimate No ETL Showdown: shortcuts vs. mirroring vs. copy job" is fully booked!

We did it! @powerbidude.bsky.social and I took 400+ people on transformative journey from data analyst to data engineer, by transitioning from Dataflows Gen2 to notebooks. Many great questions and interaction with the audience - thank you everyone for joining!

Making final polishing to a notebook for our demo-heavy session, Transitioning from Dataflows Gen2 to Notebooks, that Thomas LeBlanc and I are doing at #FabCon Atlanta. We won't talk much - we'd rather show you practical examples that you may take home with you and start applying immediately.

Finally made my way to #FabCon Atlanta! Looking forward to the full week of learning, networking, and hanging around with like-minded people.

Get the data architecture right, and everything else becomes easier. In this practical guide, @datamozart.bsky.social outlines the core architectural concepts every analytics engineer should master.

Hello Utrecht! Just arrived to the Netherlands, ready for three days of learning, sharing, and networking at Power BI Gebruikersgroep Gebruikersdag 2026. #PBIG2026

Great dashboards start with great architecture. @datamozart.bsky.social explains why understanding data architecture is essential for every analytics engineer making daily technical decisions.

Data is everywhere (except where you actually need it)😊 The old answer was: 'ETL everything'! The new answer is #MicrosoftFabric. This is a leading theme in my brand-new session that will have its premiere at #FabCon Atlanta. We'll compare shortcuts, mirroring, and Copy Job features.

This is a great write-up by Tony Alicea, my fellow Pluralsight author, about the (possible) future of self-paced online education. As someone who is deeply in this topic, I thoroughly enjoyed the reading: tonyalicea.dev/blog/the-fut...
