In summary, Cosmos DB is great at storing and retrieving complex, non-relational data that potentially needs geographic performance. Keep in mind though, that replicas are always read-only replicas, and you only have one writable node. And better yet, you can keep communicating with your app as you did before and Cosmos DB will figure out which database in which region is the most performant for you. You just indicate the region and data are replicated in real-time. On top of this, performance is part of the SLA, where Microsoft promises a maximum of 10ms latency for reading operations and 15ms latency for write operations.Īdditionally, it is very easy to create a geographic performance by having Cosmos DB replicate data to another region. There is no need for you to tune your database, this happens automatically. The database itself is highly performant, regardless of the API that you use and takes care of indexes automatically.

This means that if you now have an app that stores data in Gremlin, you can just point that app to a Cosmos DB instance and take advantage of all the additional features.Īnother notable thing about Cosmos DB is the focus on performance. You can use the original (SQL-like) DocumentDB query language, JavaScript, Gremlin, MongoDB and Table Storage. One very appealing aspect of Cosmos DB is that you can use different APIs to talk to it. If you want to store non-relational data and use that all over the world with great performance than Azure Cosmos DB is the database for you.Ĭosmos DB is the rebranding of DocumentDB and adds lots of features. In general, Azure Storage is highly performant and inexpensive but offers limited querying capabilities. This ensures that your data is safe in case of failure or disaster. You can choose to also have the storage replicate to another data center using the Geo-redundant storage tier, which then also creates 3 copies of your data in a secondary data center, making the total number of copies 6. Additionally, by default, everything you store in Azure Storage is replicated 3 times within the chosen data center.

If you cannot find it, you can follow this blog post to download and install it. This may be different for you, but, given that you have chosen to install the SQL Server tools with Visual Studio, you’ll probably find in a similar folder. In my case, this was installed as part of Visual Studio 2019, and I could find the sqlpackage.exe tool under the C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\Extensions\Microsoft\SQLDB\DAC\150 folder. Installing the SqlPackage toolīefore you get started, you will need to ensure that you have the SqlPackage tool installed. This blog post will take you through the process of creating a backup of a SQL Azure database and restore it to a LocalDB database on your computer using the SqlPackage tool.
