We might be interested to know the internals of SQL Server Always On. In the next section, let’s see how actually data synchronization happens in both Synchronous and Asynchronous data commit mode. Data Synchronization in Synchronous data commit mode In the following image, we can see the over...
Data Sync is useful in cases where data needs to be kept updated across several databases in Azure SQL Database or SQL Server. Here are the main use cases for Data Sync: Hybrid Data Synchronization:With Data Sync, you can keep data synchronized between your databases in SQL Server and Azure...

Reinitialize affected subscribers or execute sp_addtabletocontents to ensure that data added is included in the next synchronization. 4837 16 No Cannot bulk copy into a table "%.*s" that is enabled for immediate-updating subscriptions. 4838 16 No The bulk data source does ...
After you upgrade the old primary, you may need to resume synchronization. It is recommended to upgrade all secondary replicas before failing over to a replica with the new version. That way you have the option of doing a failover after the database(es) are upgraded to the new format....
an application obtains changes by using CHANGETABLE(CHANGES ...), the application must validate the value forlast_synchronization_versionthat it plans to pass to CHANGETABLE(CHANGES ...). If the value oflast_synchronization_versionisn't valid, that application must reinitialize all the data. ...
Similar to AGs, but this time using the transaction log as the synchronization method, the data propagation can be started well in advance of the server switch. At the time of the switch, once all traffic is stopped at the source, a final transaction log would need to be taken, copied,...
