I've written a getting started article you can read to understand a bit more about Git. Git provides capabilities to help you track and audit script changes over time. This seems like an extra step to many DBAs, but it really isn't. This is where I can work with any of the changes I've made to code and commit them to my git repository. You can see it in the image below, the second from the bottom icon with the pointer hovering over it. If we look at the ADS sidebar, there is a VCS icon, which looks like a git branch graph, two connected curved lines with circles at the ends. This is unlike SSMS, which is based on Visual Studio, but doesn't have a lot of the VS capabilities, including version control features. Git support was built into VS Code, and it wasn't disabled in ADS. A Dedicated PaneĪDS is built on Visual Studio Code, which is a tool I use often for non-SQL work. This post continues my look at Azure Data Studio (ADS) with an examination of the version control features built into the product. This is important to protect code, allow us to undo problem changes by finding old code, and ensuring that all changes made by a team are captured in a central place. Instance, so no need to install it on the same machine.One of the more important things that I think we should be doing as software developers is maintaining our changes in some sort of version control system (VCS). Since we will use an on-premises server, download and install theĭata sync agent, this can be installed on a machine with access to the SQL Server Install Azure Data Sync Agent on-premises The best way to understand how it works is with an example, so let's replicateĭata between an Azure SQL Database and an on-premises SQL Server 2019 instance. At the time of the writing of this tutorial, Azure SQL Managed instances are For the above scenarios, there are specific solutions for each case that haveīetter performance. Replicas, ETL processes and migrations (delta migrations are acceptable). Not recommended scenariosĪzure SQL Data sync is not recommended for: disaster recovery, read-only To check the complete list of limitations you can check the Snapshot isolation must be enabled on involved databases. Tables involved must have a primary key defined and cannot be changed while For on-premises member databases, you need to download and install theĭata Sync agent (we will see this later this tip). What is needed?Īs we mentioned before you need a hub database, this must be an Azure SQL Database. This databaseĬannot be deleted while is part of a sync group. You must create a sync metadata database in the same region and subscriptionĪs the Hub database, Microsoft recommends that this is an empty database. Member databases can be Azure SQL databases or on-premises databases. The hub database manages the sync data with the member databases. Of data to be available on other regions to minimize latency.ĭata Sync uses an Azure SQL Database as a hub or central database, then you defineĪ sync group to include the databases to be synchronized. Globally distributed applications: if you want a specific set.Purposes on a cheaper environment to offload processing tasks from main database. Offload work: to have a specific set of data using for reporting.Hybrid environments: capability to have data on-premises and.Microsoft Documentation, these are the suggested uses for Azure Data Sync: This technology permits us to synchronize dataĪcross multiple databases in Azure or on-premises.
