  1. [In Preview] Hash distribute fact table on multiple columns

    A large fact table often has multiple join keys to multiple dimension table, so while it can be opitmised for one join it always creates data movement for other joins. The hash distribution should accept multiple columns so all joins are optimised and create no data movement for dimension joins.

  2. Resource class override

    Having a fixed resource class assigned to a user is too rigid. Most queries can be executed efficiently with a small resource class, but certain operations (e.g. rebuild index) should be run with a larger RC. I need to switch between several user accounts just to be able to have appropriate resources for whatever operation or query I need to run. Users assigned to xlargerc can only execute a single query at a time.

    Would be great to be able to set/change the resource class used for executing each statement. Alternatively, being able to execute as a different user could…

    We announced workload isolation via workload groups for public preview at Ignite in Nov., 2019. Workload groups allow you to create your own custom resource classes (among other things). Check out workload classification that allows you to assign requests by more than just login information too!

  3. Better Database & Query Monitoring through Azure Portal

    Enable a better experience when it comes to monitoring and analysis of queries and DWH/query performance. Currently the SQL DW blade in the Azure Portal does only show very basic information about queries and their execution as well as DTUs with no possibility to customize the charts or the (query) lists. Only the last 50 queries are shown in this list, there are no overall reports and statistics (long running queries), there is no possibility to filter this list or show other metrics. Please enable a similar experience for monitoring of query and DB performance like SQL DB offers (Query…

    We are actively improving our monitoring experience. We have future improvements on our road map such as Query Data Store and integrating with Azure Monitor (logs and metrics) for near real time troubleshooting in the Azure portal. If anyone has any other feedback, please elaborate on your scenario on this thread and have your team continue to vote. Thank you for your continued support!
