Although we all agree that Polars/Pandas/DuckDB is faster on single node, the Spark Engine has a strong, nearly bug free API that has many efficient implementations (e.g. one of the best Delta/Iceberg/Hudi Writers). It also offers Stream Processing across many matured data sources.   There's nearly 15 years worth of rich tutorials on Spark patterns. Copilot/AI is extremely proficient at producing high-quality Spark code. Data Engineers can be highly productive in Spark in a very short period of ramp up. It is also a great API to learn, since all hyperscalers offer a managed Spark runtime, so it's easy to find a Data Engineering role (job security etc.)   Spark Declarative Pipelines will also significantly reduce the barrier to entry to writing ETL code: Spark Declarative Pipelines Programming Guide - Spark 4.1.0-preview1 Documentation   But - due to the lack of a cheap/fast/single-node runtime, instead of taking advantage of these awesome API investments in Spark Engine, many Data Engineers who have smaller volume of data end up writing entire heterogenous API centric codebases, when they could just use the Spark API and it's innovations, so the code can scale out when the job needs to with simple config changes, or run in local mode when it doesn't need to.   Ideally, one day Fabric could offer a serverless Spark runtime, but until then, it might be fairly easy to tune up a single-node Spark runtime that is opinionated with spark configs that do not force shuffles. Perhaps NEE could back this runtime to reduce the memory footprint as well.   OSS Apache Spark can run pretty fast(er) on a single node if you tweak a few settings. The problem is, you need to be a Spark Expert to read these things and tweak it. It'd be good if Fabric could do this for laymans.   How to Speed Up Spark Jobs on Small Test Datasets How to cut the run time of a Spark SBT test suite by 40% | by Matthew Powers | Medium Setting Shuffle Partitions in order to limit the number of Tasks by qnob · Pull Request #291 · holdenk/spark-testing-base Spark Standalone Mode - Spark 4.0.1 Documentation   For non-distributed datasets on a single VM, Fabric could go ahead and provision a Spark runtime that is Executor heavy, say, on a 6 core VM, do this:   Here's an example of an opinionated spark config ```yaml spark:   local: true                           # Fire spark in local[*] mode   ui: false                               # Turn off Spark UI to save resources   offHeapEnabled: false        # Disable offheap   driverCore: 1                       # Driver doesn't do much, reduce it more if needed   driverMemory: "512mb"    # "   executorCore: 5                 # Executor does the most work, I'm not sure if odd numbers are allowed 🙂   executorMemory: "11.5g"  # "   shufflePartitions: 1             # Don't need shuffles on small data sizes ``` ...

When writing a bulleted list in a text box in Power BI, if the font size is set to 12, the text in the list shows at the equivalent of font size 9. All other font sizes show as expected, size 12 is the only size that shrinks. My current workaround is to make all bulleted lists size 11, but it is against my organisation's accessibility guidelines to have any text smaller than size 12 on a webpage. ... View more

Currently, it is possible to get the value sets for a variable library via Items - Get Variable Library Definition - REST API (VariableLibrary) | Microsoft Learn but since it's an LRO, there's a high cost in time & processing to get the values (e.g. wait for the operation, getting the defintion, procesing the body, converting the payload, etc.)    The idea is to make avaialble an interface that returns the valueset for a given variable library/variable, example ...  GET https://api.fabric.microsoft.com/v1/workspaces/{workspaceId}/VariableLibraries/{variableLibraryId}/variables/{variableId}/valueset   This will be equivalent to the functionality exposed by notebookutils  samplevl = notebookutils.variableLibrary.getLibrary("sampleVL") samplevl.test_int samplevl.test_str   ...

Anyone who uses PowerBI long enough has had a PBIX with 50-60 measures and it has become time consuming and tedious to mantain. In Excel you can do a quick find/replace to edit several formulas - in PowerBI you need to select each one individually. An "excel-like" interface for editing measures would save a lot of time! This would take PowerBI to the next level regarding productivity. I've prepared a mockup for this as well as a DAX Editor. Let me know what you think. Mockup: https://i.imgur.com/z6TBOQb.png?1 ...

If it was possible to offer a robust and customizable style management system for the matrix, it could be the key to enhancing the professional appearance of tables and matrices. Further, giving report creators the ability to adjust gridlines, color, style, and the addition of custom icons, bars, sparklines, and other elements, along with a variety of pre-designed styles, would significantly improve style management options for tabular elements. ...

We’re exploring support for computed columns in Fabric DW - columns derived from expressions over other columns (for example, totals, normalized values, or derived flags).  For eg:    CREATE TABLE Products (   Price decimal(10, 2),   Tax decimal(10, 2),   TotalPrice AS (Price + Tax) PERSISTED );   These columns are not physically stored (unless marked as PERSISTED in SQL Server) but are computed on the fly during query execution. Computed columns are supported in SQL Server and Azure Synapse.    Would this be useful for your workloads? • What scenarios would you use computed columns for? • Would you prefer persisted vs non‑persisted? • Any performance or usability considerations we should keep in mind? We’d love to hear your feedback. ... View more

Problem: Developers and reviewers with edit permissions frequently open notebooks for reading. Notebooks currently open in edit mode with autosave, which causes accidental changes and noisy version history. Request: Open notebooks in View‑only mode by default, or at least add an option (user preference or workspace/tenant policy) to open notebooks in view-only mode.  Edit mode should require intentional button click. Benefits: prevents accidental edits, reduces accidental autosaves, safer review workflows, aligns Fabric with other notebook UX patterns (view-first), prevents false "notebook has been updated" triggers in IDE. ...
