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?

    • 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.

      • Allow multiple logins to same server/database

        Allow adding same server and same database with different logins. Currently if I try to add another connection to the same database on the same server, the action is aborted.

        • 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.

          • Allow IaaS to PaaS

            Allow Data to Sync from a VM running SQL to an Azure SQL PaaS model, provided the Database passes the compatibility test.

            • Where can one find SQL Data Sync options in the new portal?

              Windows Azure is announcing that SQL Database will no longer be available on the new portal. What will happen to Sync Preview feature. We use it to deliver a very useful business system for our clients. Hope we can see this option in the new portal to help us deliver more

                • trustServerCertificate

                  Allow the connection parameter trustServerCertificate=true to be set. This would allow SSL connections to be used even if the certificate is not perfect. Better than being forced to using an non encrypted connection.

                  • Enable PaaS-to-PaaS Transactional Replication

                    When can we expect to be able to replicate from PaaS to PaaS? Sync agent is the only way to do this right now, and as everyone knows this is not the ideal solution (still in preview? support will never assist with issues...). Otherwise, we're being asked to pay high costs for the PREMIUM tier just to get active/readable replication. Or, go with an IaaS solution. Really hoping something is in the works here...

                      Why is there no option to do SQL Data Sync in the Azure Portal? It makes it seem like one of the ideas that may not get out of preview !

                      • 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

                        • What happened to Sync Preview for SQL Databases in the new portal?

                          I can no longer figure out how to access the Sync for SQL Azure Databases. This needs to be put into the new portal so it can be found without going back to the old one.

                          • 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

                            • 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.

                                • Provide a roadmap for SQL Data Sync

                                  Provide information on what Microsoft has in store for the future of Data Sync. There has been hardly any work or updates to it in years, it has been in preview for that whole time.
                                  I really want to use this service as there is no equivalent on the market, but am hesitant to as it could be discontinued at any time.

                                  Is this product dead?

                                    Thanks for the suggestion! We are actively working on the roadmap, and will share publically when we have a concrete plan. Meanwhile, it would be great if you could share with us what scenario are you looking to use sync for. If you would like to be contacted offline, do leave a message and I’ll get back to you. — Linda Wang

                                  • SQL Data Sync API to manually trigger a sync

                                    We need a way to force a sync. With the minimum sync window of 5 mins we cannot guarantee prevention of data contention. For example, in a bookings system, the on premises database is always 5 mins out from potential web updates. Maintenance users want to add exclusions or blocks and need to know no new bookings were made in those slots. Likewise, if the on premises database makes entries, it needs to force those entries immediately to the web and not wait for the Sync. We see this as an important architectural requirement to an otherwise impressive service.

                                      Presently there is option to change the subscription of azure SQL server but there is no such option to change\move the DataSync to other subscription.

                                      • Allow continuous synchronisation or intervals less than 5 minutes

                                        Current smallest interval is 5 minutes, allow me to set this to between 1 and 4 minutes or a continuous synchronisation option. A wait of up to 5 minutes for sync is not always acceptable.

                                        • 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!
