Use CData Connect Cloud to connect to live Amazon Athena data in Redash for querying, visualizing, and sharing.
Redash is a collaboration tool that lets you query, visualize, and share your data. When paired with CData Connect Cloud, Redash gets access to live Amazon Athena data. This article demonstrates how to connect to Amazon Athena using Connect Cloud and work with live Amazon Athena data in Redash.
CData Connect Cloud provides a pure SQL Server interface for Amazon Athena, allowing you to query data from Amazon Athena 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 Athena, leveraging server-side processing to return the requested Amazon Athena data quickly.
Configure Amazon Athena Connectivity for Redash
Connectivity to Amazon Athena from Redash is made possible through CData Connect Cloud. To work with Amazon Athena data in Redash, we start by creating and configuring a Amazon Athena connection.
- Log into Connect Cloud, click Connections and click Add Connection
- Select "Amazon Athena" from the Add Connection panel
-
Enter the necessary authentication properties to connect to Amazon Athena.
Authenticating to Amazon Athena
To authorize Amazon Athena requests, provide the credentials for an administrator account or for an IAM user with custom permissions: Set AccessKey to the access key Id. Set SecretKey to the secret access key.
Note: Though you can connect as the AWS account administrator, it is recommended to use IAM user credentials to access AWS services.
Obtaining the Access Key
To obtain the credentials for an IAM user, follow the steps below:
- Sign into the IAM console.
- In the navigation pane, select Users.
- To create or manage the access keys for a user, select the user and then select the Security Credentials tab.
To obtain the credentials for your AWS root account, follow the steps below:
- Sign into the AWS Management console with the credentials for your root account.
- Select your account name or number and select My Security Credentials in the menu that is displayed.
- Click Continue to Security Credentials and expand the Access Keys section to manage or create root account access keys.
Authenticating from an EC2 Instance
If you are using the CData Data Provider for Amazon Athena 2018 from an EC2 Instance and have an IAM Role assigned to the instance, you can use the IAM Role to authenticate. To do so, set UseEC2Roles to true and leave AccessKey and SecretKey empty. The CData Data Provider for Amazon Athena 2018 will automatically obtain your IAM Role credentials and authenticate with them.
Authenticating as an AWS Role
In many situations it may be preferable to use an IAM role for authentication instead of the direct security credentials of an AWS root user. An AWS role may be used instead by specifying the RoleARN. This will cause the CData Data Provider for Amazon Athena 2018 to attempt to retrieve credentials for the specified role. If you are connecting to AWS (instead of already being connected such as on an EC2 instance), you must additionally specify the AccessKey and SecretKey of an IAM user to assume the role for. Roles may not be used when specifying the AccessKey and SecretKey of an AWS root user.
Authenticating with MFA
For users and roles that require Multi-factor Authentication, specify the MFASerialNumber and MFAToken connection properties. This will cause the CData Data Provider for Amazon Athena 2018 to submit the MFA credentials in a request to retrieve temporary authentication credentials. Note that the duration of the temporary credentials may be controlled via the TemporaryTokenDuration (default 3600 seconds).
Connecting to Amazon Athena
In addition to the AccessKey and SecretKey properties, specify Database, S3StagingDirectory and Region. Set Region to the region where your Amazon Athena data is hosted. Set S3StagingDirectory to a folder in S3 where you would like to store the results of queries.
If Database is not set in the connection, the data provider connects to the default database set in Amazon Athena.
- Click Create & Test
- Navigate to the Permissions tab in the Add Amazon Athena 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 Athena from Redash using Connect Cloud
To establish a connection from Redash to CData Connect Cloud using the SQL Server API, follow these steps.
- Log into Redash.
- Click the settings widget on the top right.
- Click New Data Source.
- Select Microsoft SQL Server as the Data Source Type.
-
On the configuration tab, set the following properties:
- Database Name: enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, Salesforce1).
- Server: enter the virtual SQL Server host name (tds.cdata.com)
- User: enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, [email protected].
- Password: enter the PAT you generated on the Settings page.
- Port: enter 14333
- Click Create.
- Click Test Connection to ensure that the connection is configured properly.
You can now work with live Amazon Athena data in Redash.
