Use CData Connect Cloud to create a linked server for live Amazon DynamoDB data.
SQL Server Linked Servers enable the SQL Server Database Engine to read data from remote data sources and execute commands against the remote database servers outside of the instance of SQL Server. Typically, linked servers are configured to enable the execution of a T-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle. When paired with CData Connect Cloud, linked servers provides instant access to Amazon DynamoDB data from your SQL Server database. This article demonstrates how to connect to Amazon DynamoDB using Connect Cloud and query Amazon DynamoDB data in SQL Server Management Studio (SSMS).
CData Connect Cloud provides a pure SQL Server interface for Amazon DynamoDB, allowing you to query data from Amazon DynamoDB without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to Amazon DynamoDB, leveraging server-side processing to return the requested Amazon DynamoDB data quickly.
Configure Amazon DynamoDB Connectivity for SQL Server
Connectivity to Amazon DynamoDB from SQL Linked Servers is made possible through CData Connect Cloud. To work with Amazon DynamoDB data from SQL Linked Servers, we start by creating and configuring a Amazon DynamoDB connection.
- Log into Connect Cloud, click Connections and click Add Connection
- Select "Amazon DynamoDB" from the Add Connection panel
-
Enter the necessary authentication properties to connect to Amazon DynamoDB.
The connection to Amazon DynamoDB is made using your AccessKey, SecretKey, and optionally your Domain and Region. Your AccessKey and SecretKey can be obtained on the security credentials page for your Amazon Web Services account. Your Region will be displayed in the upper left-hand corner when you are logged into DynamoDB.
- Click Create & Test
- Navigate to the Permissions tab in the Add Amazon DynamoDB Connection page and update the User-based permissions.
Add a Personal Access Token
If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.
- Click on your username at the top right of the Connect Cloud app and click User Profile.
- On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
- Give your PAT a name and click Create.
- The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
Connect to Amazon DynamoDB from SQL Server using Connect Cloud
To establish a connection from SQL Server Linked Server to the CData Connect Cloud Virtual SQL Server API, follow these steps.
- Open Microsoft SQL Server Management Studio.
- In the Object Explorer pane, open Server Objects, right-click Linked Servers, and select New Linked Server.
-
The New Linked Server dialogue opens. On the General page, enter the following information:
- Enter a name for the server in the Linked server field.
- Select the radio button Other data source and select SQL Server Native Client 11.0 as the provider.
- In the Data source field, enter tds.cdata.com,14333
- In the Catalog field, enter enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, AmazonDynamoDB1).
-
Select the Security page. At the bottom, select the radio button labeled Be made using this security
context and enter the following information:
- Remote login - enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, [email protected].
- With password - enter the PAT you generated on the Settings page.
- Click OK to create the server. Your linked server can now be used to access the data in the data source you specified. If you need to access data from more sources, create another linked server for each one.
Execute Queries
You can now execute queries to the Amazon DynamoDB linked server from any tool that can connect to SQL Server.
An example SQL query would be:
SELECT * FROM [CDATA CONNECT CLOUD].[AmazonDynamoDB1].[AmazonDynamoDB].[Lead]
We have successfully created a linked server that allows us to query Amazon DynamoDB data.
