Analyze Amazon DynamoDB Data in Infragistics Reveal
Use the CData API Server to create an OData API on top of Amazon DynamoDB data and visualize live Amazon DynamoDB data in Ingragistics Reveal.
Reveal is a data visualization solution provided by Infragistics and can be paired with the CData API Server and Amazon DynamoDB ADO.NET Provider to build dynamic dashboards from live Amazon DynamoDB data. The CData API Server generates an OData API for Amazon DynamoDB, which is natively consumable in Reveal. In this article, we walk through connecting to Amazon DynamoDB in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.
Connect to Amazon DynamoDB from API Server
CData API Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Open API Server and click Settings -> Connection -> Add Connection
- Select "Amazon DynamoDB"
- 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.
Add Amazon DynamoDB Resource Definitions in API Server
After connecting to Amazon DynamoDB, create Resources, which represent API endpoints for Amazon DynamoDB data.
- Click Settings -> Resources -> Add Resource
- Select the Amazon DynamoDB connection
- Select the table you wish to retrieve and click Next
- (Optional) Edit the resource to select specific fields and more
- Save the settings
Add an API Server User
Create a User to connect to Amazon DynamoDB from Reveal through API Server.
- Click Settings -> Users
- Click Add
- Configure a User with access to the Amazon DynamoDB Connection and Resource(s)
(Optional) Configure Cross-Origin Resource Sharing (CORS)
When accessing and connecting to multiple different domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in Settings -> Server.
- Enable cross-origin resource sharing (CORS): ON
- Allow all domains without '*': ON
- Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
- Access-Control-Allow-Headers: Authorization
Save the changes to the settings.
Create a Dashboard in Reveal
With the API Server configured, we can visualize Amazon DynamoDB data in Reveal.
- Log into Reveal and click Dashboards -> New
- Click Data Source -> OData Feed
- Specify the API Server API endpoint URL, for example: https://serverurl/api.rsc
- Select Generic Credentials and specify the API Server username and authentication token
- Select the entity you wish to visualize
- Select fields and choose a chart type
