This article walks through the process of configuring a DSN on the client and server machines, publishing a data source for Athena to Tableau Server, and publishing an entire Workbook to Tableau Server (including the data source). If you publish a data source, you will be able to create new, refreshable workbooks in Tableau Server.

Athena にODBC データソースとして接続を確立

To create a data source or workbook in Tableau Desktop and publish the data source or workbook to Tableau server, you will need to configure a DSN on each machine (Desktop and Server), specifying connection properties and creating DSNs using the same name on each machine. Information for connecting to Athena follows, along with different instructions for configuring a DSN in Windows and Linux environments.

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:

  1. Sign into the IAM console.
  2. In the navigation pane, select Users.
  3. 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:

  1. Sign into the AWS Management console with the credentials for your root account.
  2. Select your account name or number and select My Security Credentials in the menu that is displayed.
  3. 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.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Windows

If you are installing the CData ODBC Driver for Athena on Windows, DSN configuration is the last step of the driver installation. If you already have the driver installed, or you wish to configure new DSNs, you can use the Microsoft ODBC Data Source Administrator.

Linux

If you are installing the CData ODBC Driver for Athena in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData AmazonAthena Source] Driver = CData ODBC Driver for Athena Description = My Description AccessKey = 'a123' SecretKey = 's123' Region = 'IRELAND' Database = 'sampledb' S3StagingDirectory = 's3://bucket/staging/'

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Athena データソースをTableau に公開

With the connections to Athena data configured, you are ready to publish a Athena data source on Tableau, ready to be leveraged by users in your organization to create workbooks based on Athena data.

Create and Publish a Data Source

  1. In the Connect pane, click More -> Other Databases (ODBC). Select CData AmazonAthena Sys, the system DSN.

    The driver installation automatically creates matching user and system DSNs: The system DSN is needed to connect from Tableau Server.

  2. In the Database menu, select CData.
  3. In the Table box, enter a table name or click New Custom SQL to enter an SQL query.
  4. Drag the table onto the join area.
  5. From the Server menu, click Publish Data Source -> (YOUR DATA SOURCE).
  6. Enter the URL to the server. For most instances, you will authenticate with the Tableau Server username and password. Other authentication scenarios can be found below:
    • If Tableau is configured to use Kerberos and your computer has valid Active Directory credentials, Tableau connects to the server.
    • If Tableau is configured to use SAML, a login prompt for your external identity provider is displayed.
    • If Tableau is configured to use Active Directory, enter your Windows username and password.
  7. In the resulting dialog, set the Project, Data Source, and other properties. If you want to schedule refreshes, select Embedded Password in the Authentication menu. Click Publish.

You and other users in your organization can now create and share workbooks based on the published data source.

Refresh Workbooks

With a system DSN configured on the client (Tableau Desktop) machine and server (Tableau Server) machine, you can refresh workbooks connected to the Athena data source. From the Web interface for Tableau Sever, click Data -> (YOUR DATA SOURCE) -> Refresh.

Publish a Completed Workbook with Athena Data to Tableau Server

If you have a specific Workbook that you wish to share with your organization, you can create the Workbook on Tableau Desktop and publish the Workbook directly to Tableau Server.

  1. To connect to Athena and select data, follow steps 1-5 above.
  2. Click Server -> Sign in and configure the connection to the server. For most instances, you will authenticate with the Tableau Server username and password. Other authentication scenarios can be found below:
    • If Tableau is configured to use Kerberos and your computer has valid Active Directory credentials, Tableau connects to the server.
    • If Tableau is configured to use SAML, a login prompt for your external identity provider is displayed.
    • If Tableau is configured to use Active Directory, enter your Windows username and password.
  3. With the data selected, select dimensions and measures to visualize and select a type of chart or graph to build your visualization(s).
  4. Once the Workbook is complete, click Server -> Publish Workbook to publish the Workbook to Tableau Server.
  5. In the resulting dialog, set the Project, Name, Description and other properties. If you want to schedule refreshes, click Edit under Data Sources and change the Authentication option to Embedded Password. Click Publish.

You and other users in your organization can now review the published workbook from Tableau Server.
