Use CData Connect Cloud to connect to Amazon Athena Data from Nintex Workflow Cloud and build custom workflows using live Amazon Athena data.
Nintex Workflow Cloud is a cloud-based platform where you can design workflows to automate simple or complex processes using drag-and-drop interactions — without writing any code. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to Amazon Athena data for business applications. This article shows how to create a virtual database for Amazon Athena in Connect Cloud and build a simple workflow from Amazon Athena data in Nintex.
CData Connect Cloud provides a pure, cloud-to-cloud interface for Amazon Athena, allowing you to build workflows from live Amazon Athena data in Nintex Workflow Cloud — without replicating the data to a natively supported database. Nintex allows you to access data directly using SQL queries. 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 quickly return the requested Amazon Athena data.
About Amazon Athena Data Integration
CData provides the easiest way to access and integrate live data from Amazon Athena. Customers use CData connectivity to:
- Authenticate securely using a variety of methods, including IAM credentials, access keys, and Instance Profiles, catering to diverse security needs and simplifying the authentication process.
- Streamline their setup and quickly resolve issue with detailed error messaging.
- Enhance performance and minimize strain on client resources with server-side query execution.
Users frequently integrate Athena with analytics tools like Tableau, Power BI, and Excel for in-depth analytics from their preferred tools.

Getting Started
Configure Amazon Athena Connectivity for Nintex
Connectivity to Amazon Athena from Nintex is made possible through CData Connect Cloud. To work with Amazon Athena data from Nintex, 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.
With the connection configured, you are ready to connect to Amazon Athena data from Nintex Workflow Cloud.
Connect to Amazon Athena from Nintex
The steps below outline creating a new connection to Amazon Athena data from Nintex (via Connect Cloud).
- Log into Nintex Workflow Cloud
- In the Connections tab, click "Add new"
- Select "Microsoft SQL Server" as the connector and click "Connect"
- In the SQL Server connection wizard, set the following properties:
- Connection Name: a Connect Cloud
- Username: a Connect Cloud username (e.g. [email protected])
- Password: the Connect Cloud user's PAT
- Database Host: tds.cdata.com
- Database Name: the Amazon Athena connection (a.g., AmazonAthena1)
- Click "Connect"
- Configure the connection permissions and click "Save permissions"
Create a Simple Amazon Athena Workflow
With the connection to CData Connect Cloud configured, we are ready to build a simple workflow to access Amazon Athena data. Start by clicking the "Create workflow" button.
Configure the Start Event Action
- Click the start event task and select the "Form" event
- Click "Design form"
- Drag a "Text - Long" element onto the Form and click the element to configure it
- Set "Title" to "Enter SQL query"
- Set "Required" to true
- Drag a "Text - Short" element onto the Form and click the element to configure it
- Set "Title" to "Enter desired result column"
- Set "Required" to true
Configure an "Execute a Query" Action
- Add an "Execute a query" action after the "Start event: Form" action and click to configure the action
- Set "SQL Script" to the "Enter SQL Query" variable from the "Start event" action
- Set "Column to retrieve" to the "Enter desired result column" variable from the "Start event" action
- Set "Retrieved column" to a new variable (a.g., "values")
Configure a "Send an Email" Action
- Add a "Send an email" action after the "Execute a query" action and click to configure the action
- Set the "Recipient email address"
- Set the "Subject"
- Set the "Message body" to the variable created for the retrieved column
Once you configure the actions, click "Save," name the Workflow, and click "Save" again. You now have a simple workflow that will query Amazon Athena using SQL and sand an email with the results.
