  1. 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.

  2. 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.

  4. 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

  5. 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

  6. SSDT Visual Editor Support

    SSDT Visual Table editor is disabled with Synapse. Please add support for this feature. This is one of the reasons to use SSDT over SSMS for development.

  7. Export Restore Point to Blob storage for Long term backups or migrating data

    To be able to export a Restore Point to Blob Storage to meet Compliance data retention policy's, and be able to restore a warehouse from the blob data set. We are on legal hold and not allow to delete backups at this time and the only way to meet this requirement is to export the each table to blob.

  8. 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.

  9. 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. 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.

  12. 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.

  13. 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.

  15. 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.

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

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

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

  18. sys.dm_db_stats_properties

    Implement the sys.dmdbstatsproperties DMV to expose the modctr 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.

  19. Automatic Generation and Updating of table statistic

    It would be great if table statistics were automatically created and updated in Azure Data Warehouse.

  20. Pause Resume Azure SQL Data Warehouse Using SQL Command

    It would be great if we can have SQL command to Pause/Resume DB instance like how we do for Scale up/down (under Master DB). This will help us to manage the same from ADF and don't have to worry about trigger REST API or PowerShell
