Intro

Amazon Athena is a serverless, interactive query service that lets you analyze big data in S3 using standard SQL. Use Domo's Amazon Athena connector to query data from your Athena instance. To learn more about the Amazon Athena API, visit their page (https://aws.amazon.com/documentation/athena/).

You connect to your Amazon Athena account in the Data Center. This topic discusses the fields and menus that are specific to the Amazon Athena connector user interface. General information for adding DataSets, setting update schedules, and editing DataSet information is discussed in Adding a DataSet Using a Data Connector.

Prerequisites

To connect to your Amazon Athena account and create a DataSet, you must have the following:

  • Your AWS access key.

  • Your AWS secret key.

  • The Amazon S3 location to which the query output is written (e.g. s3://aws-athena-query-results-1234-us-west-2/). You can find this by going to Settings in the Athena web console.

For information about obtaining AWS credentials, visit http://docs.aws.amazon.com/general/l...red-types.html.

Connecting to Your Amazon Athena Account

This section enumerates the options in the Credentials and Details panes in the Amazon Athena Connector page. The components of the other panes in this page, Scheduling and Name & Describe Your DataSet, are universal across most connector types and are discussed in greater length in Adding a DataSet Using a Data Connector.

Credentials Pane

This pane contains fields for entering credentials to connect to your Amazon Athena account. The following table describes what is needed for each field:  

Field

Description

Access Key

Enter your AWS access key.

Secret Key

Enter your AWS secret key.

S3 Staging Directory

Enter the S3 staging directory to which the query output will be written. For more information, see "Prerequisites," above.

Region

Select your AWS region.

Once you have entered valid Amazon Athena credentials, you can use the same account any time you go to create a new Amazon Athena DataSet. You can manage connector accounts in the Accounts tab in the Data Center. For more information about this tab, see Managing User Accounts for Connectors.

Details Pane

This pane contains a number of options for entering your query and configuring the report.
