  1. Support for tracking deadlock in SQLDW

    Currently SQLDW doesn't have option to track deadlocks. It would be good if that option is available in Azure Portal as like SQL Database

  2. Add ActiveQueryCount to REST API property outputs

    Provide ActiveQueryCount as a result output under .properties for the REST API database state parameter.

  3. Auto-suspend and Auto-resume

    I would absolutely magic if we had something like Snowflake:
    - Automatically suspends the warehouse if no query has been issued during a fixed amount of time
    - Automatically resumes the warehouse when a query is issued

  4. AutoPause after user-defined inactive period

    Especially in dev environments, a currently running dw with no active queries is a waste. Some guard rails to protect users from themselves would be useful.

    Something like the feature in databricks.

  5. Allow both primary and secondary maintenance to be scheduled on Saturday and Sunday

    Primary and Secondary maintenance must be mutually exclusive (either Saturday / Sunday or during weekdays); We run batch jobs daily, with the exception of Saturday. Must schedule maintainance on Saturday.

  6. Enable support for cross subscription restore

    The current workaround for cross subscription restore is:

    1. Restore to a new logical server in the same prod subscription
    2. ‘Move’ the new logical server with the restored data warehouse to new subscription

    It would be faster and simpler to enable restore directly to a different subscription.

  7. Ensure all billable metrics are viewable in the Azure portal

    Ideally all billable components of a Data Warehouse should be visible via the Azure Portal.

    We had a client recently who was trying to reconcile their billing, and could not do so as the DW size did not appear in the portal. This then required the DBA team to retrieve the size via the client admin tools: https://docs.microsoft.com/en-us/sql/relational-databases/databases/display-data-and-log-space-information-for-a-database?view=sql-server-2017

    Trending on billable metrics potentially also helps customers forecast their upcoming Azure costs.

  9. User Defined Retention Periods for Restore Points

    SQL DW doesn't have the capability to specify longer term retention capabilities as released for SQL DB recently. The workaround is to restore and pause. It would be great to have this capability for compliance and auditing requirements.

  10. Restore single table from backup

    The ability to restore a single table from backup, to an existing DW, would greatly assist in recovering from errors.

  11. Assign a private IP from VNET

    The current VNET endpoint solution does not allow connections via expressroute.

    Allow a private IP from the VNET to be assigned to the data warehouse, so that we can easily route to the warehouse from on prem, via expressroute. Removing the need for any complex peering or other IT infrastructure involvement.

  12. Shrinkdatabase command support

    Shrinkdatabase command should to be supported even if TDE is on or off because extra cost is charged in case that the unallocated space is huge.

  13. Resume command completes about a minute too soon

    A resume operation and a scale operation appear to return about a minute too soon. If your automated code immediately attempts to connect to the DW as soon as the Azure CLI resume or scale operation completes you often get the error "Cannot connect to database when it is paused". A simple one minute pause usually prevents this but I would like resume or scaling operations to not return before we can actually connect to the DW.

  14. sys.dm_db_stats_properties

    Implement the sys.dm_db_stats_properties DMV to expose the mod_ctr to get a better idea of when stats should be updated. using stats_date isn't a complete solution. as you have no idea if any rows have changed since that date

    Thank you for all the feedback folks. We are continuously improving the manageability experience with SQL Data Warehouse which includes automatic statistics. We will reach back out when this is on the roadmap and can share when we have an update.

  15. Columnstore system generated stat should not be user_created=1

    Create a simple columnstore table and look at sys.stats:

    create table dbo.systemDefinedStatBug with (clustered columnstore index, distribution=round_robin)
    as
    select 1 as column1, 2 as column2;

    select *
    from sys.stats s
    where s.object_id = object_id('dbo.systemDefinedStatBug')

    Notice it has a system generated "statistic". It use to be that row was marked as user_created=0 so we could easily tell that's not a regular user created stat. But these days in SQL DW it says user_created=1 on this "stat". Please fix this bug.

  16. sp_send_db_mail needs to be supported to send mails from stored procedure

    sp_send_db_mail needs to be supported to send mails from stored procedures created on Azure.

    We should have the abilities of sp_send_dbmail which was available with databases

  18. Enable Scale and Start in the same command/API call

    I should not have to start Azure SQL Data Warehouse, wait for it to resume then issue a scale and wait again.

    Thank you for voting for this feature folks. We’d like additional information before commenting on this topic. Please provide your scenario in the comments below. We currently have Query Data Store on our roadmap.
