该实验使用 Azure CosmosDB，这个实验的点在于：

1：使用了 cosmicworks 生成了实验数据

2：弄清楚cosmosDB 的 accout Name 与 database id 和 container id 关系。

3：创建了 ADF 的连接和任务，让数据从 cosmicworks 数据库的 products 容器，迁移到 cosmicworks数据库的 flatproducts 容器。

Migrate existing data using Azure Data Factory

In Azure Data Factory, Azure Cosmos DB is supported as a source of data ingest and as a target (sink) of data output.

In this lab, we will populate Azure Cosmos DB using a helpful command-line utility and then use Azure Data Factory to move a subset of data from one container to another.

Create and seed your Azure Cosmos DB SQL API account

You will use a command-line utility that creates a cosmicworks database and a products container at 4,000 request units per second (RU/s). Once created, you will adjust the throughput down to 400 RU/s.

To accompany the products container, you will create a flatproducts container manually that will be the target of the ETL transformation and load operation at the end of this lab.

1. In a new web browser window or tab, navigate to the Azure portal (portal.azure.com).

2. Sign into the portal using the Microsoft credentials associated with your subscription.

3. Select + Create a resource, search for Cosmos DB, and then create a new Azure Cosmos DB SQL API account resource with the following settings, leaving all remaining settings to their default values:

   Setting	Value
   Subscription	Your existing Azure subscription
   Resource group	Select an existing or create a new resource group
   Account Name	Enter a globally unique name
   Location	Choose any available region
   Capacity mode	Provisioned throughput
   Apply Free Tier Discount	Do Not Apply
   Limit the total amount of throughput that can be provisioned on this account	Unchecked

   📝 Your lab environments may have restrictions preventing you from creating a new resource group. If that is the case, use the existing pre-created resource group.

4. Wait for the deployment task to complete before continuing with this task.

5. Go to the newly created Azure Cosmos DB account resource and navigate to the Keys pane.

6. This pane contains the connection details and credentials necessary to connect to the account from the SDK. Specifically:

   1. Record the value of the URI field. You will use this endpoint value later in this exercise.

   2. Record the value of the PRIMARY KEY field. You will use this key value later in this exercise.

7. Close your web browser window or tab.

8. Start Visual Studio Code.

   📝 If you are not already familiar with the Visual Studio Code interface, review the Get Started guide for Visual Studio Code

9. In Visual Studio Code, open the Terminal menu and then select New Terminal to open a new terminal instance.

10. Install the cosmicworks command-line tool for global use on your machine.

    dotnet tool install --global cosmicworks

    💡 This command may take a couple of minutes to complete. This command will output the warning message (*Tool 'cosmicworks' is already installed') if you have already installed the latest version of this tool in the past.

11. Run cosmicworks to seed your Azure Cosmos DB account with the following command-line options:

    Option	Value
    --endpoint	The endpoint value you copied earlier in this lab
    --key	The key value you coped earlier in this lab
    --datasets	product

    cosmicworks --endpoint  --key  --datasets product

    📝 For example, if your endpoint is: https­://dp420.documents.azure.com:443/ and your key is: fDR2ci9QgkdkvERTQ==, then the command would be: cosmicworks --endpoint https://dp420.documents.azure.com:443/ --key fDR2ci9QgkdkvERTQ== --datasets product

12. Wait for the cosmicworks command to finish populating the account with a database, container, and items.

13. Close the integrated terminal.

14. Close Visual Studio Code.

15. In a new web browser window or tab, navigate to the Azure portal (portal.azure.com).

16. Sign into the portal using the Microsoft credentials associated with your subscription.

17. Select Resource groups, then select the resource group you created or viewed earlier in this lab, and then select the Azure Cosmos DB account resource you created in this lab.

18. Within the Azure Cosmos DB account resource, navigate to the Data Explorer pane.

19. In the Data Explorer, expand the cosmicworks database node, expand the products container node, and then select Items.

20. Observe and select the various JSON items in the products container. These are the items created by the command-line tool used in previous steps.

21. Select the Scale & Settings node. In the Scale & Settings tab, select Manual, update the required throughput setting from 4000 RU/s to 400 RU/s and then Save your changes**.

22. In the Data Explorer pane, select New Container.

23. In the New Container popup, enter the following values for each setting, and then select OK:

    Setting	Value
    Database id	Use existing | cosmicworks
    Container id	flatproducts
    Partition key	/category
    Container throughput (autoscale)	Manual
    RU/s	400

24. Back in the Data Explorer pane, expand the cosmicworks database node and then observe the flatproducts container node within the hierarchy.

25. Return to the Home of the Azure portal.

Create Azure Data Factory resource

Now that the Azure Cosmos DB SQL API resources are in place, you will create an Azure Data Factory resource and configure all of the necessary components and connections to perform a one-time data movement from one SQL API container to another to extract data, transform it, and load it to another SQL API container.

1. Select + Create a resource, search for Data Factory, and then create a new Azure Data Factory resource with the following settings, leaving all remaining settings to their default values:

   Setting	Value
   Subscription	Your existing Azure subscription
   Resource group	Select an existing or create a new resource group
   Name	Enter a globally unique name
   Region	Choose any available region
   Version	V2
   Git configuration	Configure Git later

   📝 Your lab environments may have restrictions preventing you from creating a new resource group. If that is the case, use the existing pre-created resource group.

2. Wait for the deployment task to complete before continuing with this task.

3. Go to the newly created Azure Data Factory resource and select Open Azure Data Factory Studio.

   💡 Alternatively, you can navigate to (adf.azure.com/home), select your newly created Data Factory resource, and then select the home icon.

4. From the home screen. Select the Ingest option to begin the quick wizard to perform a one-time copy data at scale operation and move to the Properties step of the wizard.

5. Starting with the Properties step of the wizard, in the Task type section, select Built-in copy task.

6. In the Task cadence or task schedule section, select Run once now and then select Next to move to the Source step of the wizard.

7. In the Source step of the wizard, in the Source type list, select Azure Cosmos DB (SQL API).

8. In the Connection section, select + New connection.

9. In the New connection (Azure Cosmos DB (SQL API)) popup, configure the new connection with the following values, and then select Create:

   Setting	Value
   Name	CosmosSqlConn
   Connect via integration runtime	AutoResolveIntegrationRuntime
   Authentication method	Account key | Connection string
   Account selection method	From Azure subscription
   Azure subscription	Your existing Azure subscription
   Azure Cosmos DB account name	Your existing Azure Cosmos DB account name you chose earlier in this lab
   Database name	cosmicworks

10. Back in the Source data store section, within the Source tables section, select Use query.

11. In the Table name list, select products.

12. In the Query editor, delete the existing content and enter the following query:

    SELECT p.name, p.categoryName as category, p.price 
    FROM products p

13. Select Preview data to test the query's validity. Select Next to move to the Target step of the wizard.

14. In the Target step of the wizard, in the Target type list, select Azure Cosmos DB (SQL API).

15. In the Connection list, select CosmosSqlConn.

16. In the Target list, select flatproducts and then select Next to move to the Settings step of the wizard.

17. In the Settings step of the wizard, in the Task name field, enter FlattenAndMoveData.

18. Leave all remaining fields to their default blank values and then select Next to move to the final step of the wizard.

27. Delete the contents of the editor area.

28. Create a new SQL query that will return all documents where the name is equivalent to HL Headset:

    SELECT p.name, p.category, p.price 
    FROMproducts p
    WHEREp.name = 'HL Headset'

29. Select Execute Query.

30. Observe the results of the query.
