Ryan Majidimehr has an update for us:
We are excited to announce that Multi-Column Distribution (MCD) for Azure Synapse Dedicated SQL pools is now Generally Available! MCD is highly desirable for easing migrations, promotes faster query performance, and reduces data skew.
You can choose to distribute data on multiple columns to balance the data distribution in your tables and reduce data movement during query execution. Multi-Column distribution will allow you to choose up to eight columns for distribution.
Click through for the full list of changes. It seems like there’s a decent spread between the four major pool types, with the emphasis on Data Explorer pools this month.
