SQL Data Sync

Azure SQL Data Sync (Preview) is a service that enables you to synchronize the data you select across multiple SQL Server and SQL Database instances. To synchronize your data you create sync groups which define the databases, tables and columns to synchronize as well as the synchronization schedule. Each sync group must have at least one SQL Database instance which serves as the sync group hub in a hub-and-spoke topology.

If you have any feedback on Azure SQL Data Sync service, we’d love to hear it.

How can we improve SQL Data Sync?

  1. Shorten the time for loading Log page

    Currently the Azure Sync Log inside the Portal take too much time to load if my sync group was created long time ago. i.e. for those new sync group with only a few logs, it will take around 5 seconds for loading. However, I've many sync group created more than 1 year, and it will take me up to 10 minutes for viewing the first page of the logs.

    It seems the Portal will download ALL the logs to my browser even I just want to view the most recent logs (maybe I just want to view the last 10…

      You are absolutely right! The log page currently loads all log messages and there isn’t a way to filter by time range. We will add this to our backlog. Thank you for your suggestion!

    • Add a "Validate" or "Repair" function in the Sync Agent

      Currently if the "instead of" triggers are (for whatever reason) removed from a table, changes are no longer tracked. In this scenario no logs are raised anywhere and the sync continues to show a healthy state, even though changes are no longer being sync'd from the client back to the Hub.
      When a DBA or application modifies the schema of the table it is possible that the result might be a table with similar structure but now without the triggers.
      We need a quick way to check for these kind of discrepancies and fix them when detected.

      • Support filtered indexes

        We used a member database that included a table with a filtered index (i.e. WHERE is_deleted = 0).

        The initial sync recreated the table and the indexes, but omitted the where condition, which made subsequent syncs fail.

        • Are there any way to use SQL Data Sync with "Allow access to Azure Service" OFF

          As far as I know, as of now we have to enable "Allow access to Azure Service" ON when we use SQL Data Sync. However, I don't want to enable this option because any applications in Azure can pass through firewall rule and this may be security vulnerability.

          I'd appreciate it if you could provide public IP address on Azure Data Sync Agent to be restricted on Azure SQL Server's firewall rules.

          • Export-Import Sync Groups

            Have an option to script out sync groups. Or import-export sync rules, this will help save some time to set up same sync rules for multiple environments, rather than setting up sync rule for each table.

              • Sync data from Views to Tables

                Allow the data source to be a view instead of a table. Allows me to transform the data a bit before it's put up into azure.

                (Actually wonder if this it would work if I set the sync up with tables then switch them for views).

                  Interesting trial! Sync data from views will be quite complex and not always achievable. Could you comment on what kinds of transformation you need against the base table before syncing, and why you cannot sync the base table then do the transformation in cloud? – Linda Wang

                • The UI status should be more accurate of what is processing or in progress.

                  The message should be more accurate like "Processing - Sync Provisioning", "Processing - Sync of Group ID 'dsafksdfjds' in progress "

                  • SYNC Preview - sync rules not loading

                    Hello,

                    I'm using SYNC Preview to sync 2 SQL db servers located in different countries. I have a bug to report - the tab "Sync Rules" is not loading when clicked. I have experienced this issue since 10-24-2015 and am not able to successfully SYNC due to this bug. I may have to use a different cloud service to host our company's SQL databases if this bug persists as this bug makes it impossible for me to successfully sync our databases. Any info. regarding workarounds or solutions would be appreciated.

                    Thank you,
                    Andrew Tomp

                    • Have EventHub as a target for data sync

                      If Data Sync could send data to event hub reliably from SQLDB or SQL on premise one could then build your own processing, whether it be to DW, DB, stream insight, aggregate etc.

                                      • Make it possible for VS Schema Compare to ignore tables, triggers, etc added by data sync

                                        We use Schema Compare to detect/make changes to our databases. Data Sync adds a bunch of Tables, Procedures, Triggers, etc. and it makes it hard to use the schema compare tool. Just unchecking all the checkboxes so Schema Compare knows to ignore the Data Sync stuff is a pain and then we still have to wade through a ton of items every time we do a schema compare.

                                        • Support changes to composite keys

                                          Due to a legacy database and codebase issue I've encountered a situation where an update made to a key comprising a composite key on a table causes issues with the Sync process.

                                          A table has
                                          key 1: A
                                          key 2: B

                                          If an update is made to this record to change key 2 to instead have a value of C, Data sync doesn't like this.

                                          Data sync presently only takes the insert values in the trigger but doesn't consider the potential for a corresponding delete value where the key may be different. In this case it could instead look at…
