Polars now ships inside Microsoft Fabric by default. Here's how to use it alongside Fabric's other analytics tools and what that means for your data workflows.

Unlock Python Polars with this hands-on guide featuring practical code examples for data loading, cleaning, transformation, aggregation, and advanced operations that you can apply to your own data analysis projects.

Polars gets its speed from a strict type system, lazy evaluation, and automatic parallelism. Here's how each piece works under the hood.

We've migrated our own IP and several customers from Pandas and Spark to Polars. The benefits go beyond raw speed: faster test suites, lower platform costs, and an API developers actually enjoy using.

.NET 10.0 has shipped, and for the fifth year running, we benchmarked endjin's AIS.NET library and were very happy to see substantial performance gains, with no extra work required.

A troubleshooting journey through Microsoft Entra ID that reveals the subtle but critical distinction between App Registration ownership and Service Principal ownership - and why it matters for least-privilege automation.

Ix.NET 7.0.0 is now available. Because .NET 10.0 now includes LINQ for IAsyncEnumerable, Ix.NET's System.Linq.Async has had to step back. This post explains what has changed and why.

The Data Product Canvas fuses the Business Model Canvas with Data Mesh's 'data as a product' principle, combining visual strategic collaboration with product-minded data ownership.

See the Data Product Canvas in action with a real-world scenario. Follow along as we work through each building block to design a high-impact, feasible data product for a national garden center chain facing revenue challenges.

The Data Product Canvas has nine building blocks, best completed right-to-left starting with Audience and Actionable Insight, to keep data products purpose-driven and user-centred.

Turn data initiatives into business success stories with the Data Product Canvas. This practical framework helps teams design data products that deliver real value, avoid common pitfalls, and align with business objectives.

Data quality issues are one of the biggest silent killers of analytics initiatives. This post explores how to build data quality into Microsoft Fabric from the ground up.

Lakehouse integration, built-in notebook resources, and collaboration features that set Microsoft Fabric notebooks apart from Jupyter and Databricks.

Benchmarking Corvus.JsonSchema on .NET 10.0 showed an 18% free speed-up on top of .NET 8 and 9 gains — a cumulative 29% boost for LTS upgrades from .NET 8.

AI agents dominated Big Data LDN 2025, but the real story wasn't the technology, it was which organisations could actually deploy it successfully. After five years tracking industry evolution through this event, one pattern emerged clearly: the winners had built their foundations first. For CTOs making platform decisions now, the strategic imperative isn't choosing between innovation and governance; it's recognizing that governance enables innovation at scale.
