If you want to use the GraphQL protocol to query it, you might need to create a wrapper, that translates the GraphQL queries to the appropriate interface. This should be easy, because MongoDBs queries are looking pretty the same [1]. The GraphQL interface is using graphql-dotnet. It uses a Model-first approach to define and automatically generate your schema. It supports both query and mutation. It could easily be hosted on Azure Functions.

Is it possible to populate the documents somehow? V '03ef-2ffedb'. However, Cosmos expects a specific GraphSON format for the documents in order for all of their properties to be picked up during graph traversal.

Using GraphQL in Azure Functions to Access Cosmos DB

I'd recommend taking a look at both Vertex Properties and GraphSON from the Tinkerpop documentation to start to get a better idea about these topics. When adding a document through Gremlin the syntax is a name value comma separated for all properties you want to add. Try this:. Learn more. Asked 2 years, 9 months ago. Active 2 years, 9 months ago.

Trying to save document like this and when querying with Gremlin, address has both values but I'd need a label-field of somekind to tell them apart. Cosmos does support adding meta properties.

I've updated your gist to include the format that Cosmos expects when attaching meta properties through the Document APIs gist. Sign up or log in Sign up using Google. Sign up using Facebook.

May 9, Oct 24, The Power BI dashboard will display charts to show real-time information about temperature and rainfall in a region.

There are multiple ways to set up reporting dashboards on data stored in Azure Cosmos DB. Depending on the staleness requirements and the size of the data, the following table describes the reporting setup for each scenario:. This article describes the setups for scenarios 3 and 4. Power BI has a mode where incremental refresh can be configured. This mode eliminates the need to create and manage Azure Analysis Services partitions.

Incremental refresh can be set up to filter only the latest updates in large datasets. Azure Analysis Services provides a fully managed platform as a service that hosts enterprise-grade data models in the cloud. To avoid querying the entire dataset all the time, the datasets can be subdivided into Azure Analysis Services partitions, which can be refreshed independently at different frequencies.

Set up an ingestion pipeline to load weather data to Azure Cosmos DB. Configure incremental refresh - Follow the steps in incremental refresh with Power BI article to configure incremental refresh for the dataset. Add the RangeStart and RangeEnd parameters as shown in the following screenshot:. Since the dataset has a Date column that is in text form, the RangeStart and RangeEnd parameters should be transformed to use the following filter. In the Advanced Editor pane, modify your query add the following text to filter the rows based on the RangeStart and RangeEnd parameters:.

Depending on which column and data type is present in the source dataset, you can change the RangeStart and RangeEnd fields accordingly. Define the refresh policy - Define the refresh policy by navigating to the Incremental refresh tab on the context menu for the table.

Set the refresh policy to refresh every day and store the last month data. Ignore the warning that says the M query cannot be confirmed to be folded. The Azure Cosmos DB connector folds filter queries.

Load the data and generate the reports - By using the data you have loaded earlier, create the charts to report on temperature and rainfall. Publish the report to Power BI premium - Since incremental refresh is a Premium only feature, the publish dialog only allows selection of a workspace on Premium capacity.

The first refresh may take longer to import the historical data. Subsequent data refreshes are much quicker because they use incremental refresh. Construct the Analysis Services model - Open the query editor, perform the required operations to optimize the loaded data set:. Extract the month information from the table.Azure Cosmos DB is Microsoft's globally distributed multi-model database service. You then build and run a console app built using the open-source driver Gremlin. If you don't already have Visual Studio installed, you can download and use the free Visual Studio Community Edition.

Make sure that you enable Azure development during the Visual Studio setup. If you don't have an Azure subscriptioncreate a free account before you begin.

In a new browser window, sign in to the Azure portal. You can skip the Network and Tags section.

The account creation takes a few minutes. Wait for the portal to display the Congratulations! Your Azure Cosmos DB account was created page. The Add Graph area is displayed on the far right, you may need to scroll right to see it.

You'll see how easy it is to work with data programmatically. Open a git terminal window, such as git bash, and use the cd command to change to the new folder to install the sample app. Run the following command to clone the sample repository.

This command creates a copy of the sample app on your computer. Restore the NuGet packages in the project. This should include the Gremlin. Net driver, as well as the Newtonsoft. Json package.

Using Graph API and Table API with Azure Cosmos DB

You can also install the Gremlin. Net driver manually using the Nuget package manager, or the nuget command-line utility :. This step is optional. If you're interested in learning how the database resources are created in the code, you can review the following snippets.

Otherwise, you can skip ahead to Update your connection string. Create a new GremlinServer and GremlinClient connection objects using the parameters provided above:. Execute each Gremlin query using the GremlinClient object with an async task. You can read the Gremlin queries from the dictionary defined in the previous step and execute them. Later get the result and read the values, which are formatted as a dictionary, using the JsonSerializer class from Newtonsoft.

Json package:. Now go back to the Azure portal to get your connection string information and copy it into the app. From the Azure portalnavigate to your graph database account. In the Overview tab, you can see two endpoints.

Graphs library. Gremlin Endpoint - This value is used when you connect to the graph account by using Gremlin.This has enabled users to explore new ways of consuming their data with the use of the Gremlin language while still benefitting from global distribution, elastic scalability in storage and throughput, guaranteed low latency, consistency models, and enterprise-ready SLAs of Azure Cosmos DB.

This release includes several critical updates to the performance and latency, as well as expanding the application platforms that can be used with it.

These updates benefit the Gremlin query processing performance, as well as the connectivity experience when using any of the open-source Gremlin connectors.

Additional fixes were also applied to the previously known Gremlin error parsing issues that used to be experienced. We are working on a library that can be used to efficiently bulk import nodes and edges.

In the next couple of months we will automatically migrate preview accounts to the updated service. These migrations will be done in batches and instructions with the necessary changes will be sent via email. Please continue to provide feedback on what you want to see next in our service.
