Create Data Visualizations Based On Amazon DynamoDB Data in Mode



Use CData Connect Cloud to connect to Amazon DynamoDB from Mode and build visualizations using live Amazon DynamoDB data.

Mode is a collaborative data platform that combines SQL, R, Python, and visual analytics in one place. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to Amazon DynamoDB data for use in data visualizations. This article shows how to connect to Amazon DynamoDB in Connect Cloud, connect to Amazon DynamoDB data in Mode, and create a simple visualization using that data.

CData Connect Cloud provides a pure cloud-to-cloud interface for Amazon DynamoDB, allowing you to build data visualizations from live Amazon DynamoDB data in Mode — without replicating the data to a natively supported database. In order to create visualizations, users write SQL queries to gather data. 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 quickly return the requested Amazon DynamoDB data.

Configure Amazon DynamoDB Connectivity for Mode

Connectivity to Amazon DynamoDB from Mode is made possible through CData Connect Cloud. To work with Amazon DynamoDB data from Mode, we start by creating and configuring a Amazon DynamoDB connection.

  1. Log into Connect Cloud, click Connections and click Add Connection
  2. Select "Amazon DynamoDB" from the Add Connection panel
  3. 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.

  4. Click Create & Test
  5. 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.

  1. Click on your username at the top right of the Connect Cloud app and click User Profile.
  2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
  3. Give your PAT a name and click Create.
  4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to Amazon DynamoDB data from Mode.

    • Database name: enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, AmazonDynamoDB1).
    • Username: enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, test@cdata.com
    • Password: enter the PAT you generated on the Settings page
    Leave the rest of the connection settings at their default values unless you need to modify them.
  5. At the bottom of the page, click Connect to ensure that you can connect to CData Connect Cloud.
