Chris Webb covers a specific use case:
Quite a few new Dataflows Gen2 features were released recently without much fanfare, but that doesn’t mean they aren’t important. I will take a look at them all in my next few posts; in this first post I’ll look at the ability to disable V-Order on staged data.
As the (very detailed) documentation for this new feature describes, V-Order is a write-time optimisation for the parquet files that underpin the Delta tables that OneLake uses to store data. It slows down writing data to the tables but means that reading data from them, for example in Power BI Direct Lake mode, is much faster.
Click through to see how disabling V-Order can make certain staging loads faster.
