  1. TRANSACTION support for RENAME

    Since MERGE statement is not supported, we are using CTAS for preparing the new table and using the rename operation.

    Currently we do not have the TRANSACTION support for the RENAME operations.

    When we have two rename operations we may run into inconsistent state if second statement fails.

    RENAME OBJECT FinalTable TO FinalTable_Old;
    RENAME OBJECT FinalTable_Stage TO FinalTable;

    To overcome this, we need some workaround or support for transactions.

    • Specify Time Window for Service Maintenance

      Allow customers to define a window of time during the day where any internal maintenance should be performed in order to reduce impact to users during core business hours.

      We have seen that internal upgrade/migration processes in Azure Data Warehouse can sometimes have impact on running queries (ex. performance and connection issues). If we could specify a time where impact is less likely, then it would improve the overall experience and availability.

      • unit test framework

        The open source tsqlt framework requires CLR which is not available in Azure SQL DW. A framework to to write unit tests would increase trust in the queries.

          • Once a proc is executed and if we try to stop it, its not working. Sometimes it takes 6-8 hours to get it cancelled
