How to Connect AWS Athena with Power BI: A Step-by-Step Guide

Multi-cloud deployments are gaining traction due to their ability to enhance application resiliency and availability. By utilizing multiple cloud providers, organizations can mitigate risks associated with outages or downtime from a single provider. This approach also enables cost optimization, as businesses can leverage the unique strengths of each cloud platform to meet diverse requirements effectively.

By connecting Athena to Power BI Desktop using an ODBC driver, you can unlock the full potential of your data lake, combining the scalability and flexibility of AWS with the analytical power of Power BI. This integration facilitates real-time querying and enables advanced reporting without requiring data movement, making it efficient and cost-effective.

 

Part 1: AWS Setup for Athena Connection

To connect AWS Athena with Power BI, you first need to prepare your AWS environment, including setting up Athena, configuring an S3 bucket, and enabling permissions.

Step 1: Setting Up an S3 Bucket

Athena requires a designated S3 bucket to store query results. Here’s how to set it up:

  1. Go to the AWS Management Console.
  2. Navigate to S3 and click on Create Bucket.
  3. Provide a unique bucket name (e.g., unique-bucket-name-bucket).
  4. Choose the region closest to your Athena service to avoid latency.
  5. Configure bucket permissions and click Create.

Note: Ensure permissions allow Athena to write query results to this bucket.

Step 2: Configure AWS Athena

Athena allows querying of data directly from S3 without needing an active server. Follow these steps:

  1. Open the Athena Console in AWS.
  2. Under Settings, specify the S3 bucket you created earlier as the location for query results.
  3. Test the connection by running a simple query.

Step 3: Setting Up AWS IAM Roles and Permissions

Proper permissions are key for accessing Athena and S3 securely.

  1. Go to the IAM Console in AWS.
  2. Create a new IAM user with programmatic access.
  3. Attach the following policies:
    • AmazonAthenaFullAccess – Grants Athena access.
    • S3 bucket access – For testing purpose, get full access to S3 Bucket.

  1. Generate Access Key ID and Secret Access Key for the IAM user. You’ll need these credentials later.

Step 4: Install and Configure the ODBC Driver

To connect Athena with Power BI, you need to use the AWS Athena ODBC driver:

  1. Download the ODBC driver from AWS Athena ODBC Driver Page.
  2. Install the driver on your system following the installer’s instructions.
  3. Open ODBC Data Source Administrator and configure the driver:
    • DSN Name: Provide a friendly name (e.g., Athena_PowerBI).
    • AWS Region: Your Athena region (e.g., us-west-2).
    • S3 Output Location: The query result bucket (s3://your-bucket-name/).
    • Authentication: Use the IAM Access Key ID and Secret Key generated earlier.
  4. Test the connection to ensure it’s successful.

Part 2: Power BI Setup to Connect with Athena

Once your AWS environment is ready, you can integrate Athena with Power BI to start analyzing data.

Step 1: Open Power BI Desktop

  1. Launch Power BI Desktop.
  2. Go to Home > Get Data > ODBC/Amazon Athena.

Step 2: Connect to Athena via ODBC

  1. In the ODBC connection window, select the DSN you configured earlier (e.g., Athena_PowerBI).
  2. Authenticate using your AWS credentials.
  3. Once connected, Power BI will display the list of Athena databases and tables.

Step 3: Load and Transform Data

  1. Select the tables or views you want to analyze.
  2. Click Load to import the data directly into Power BI or Transform Data to open the Power Query Editor.
  3. In the Power Query Editor, you can:
    • Filter, clean, and shape the data.
    • Create calculated columns or measures.

 

Troubleshooting Common Issues

  1. Connection Failures: Ensure that your IAM permissions and S3 bucket configurations are correct.
  2. Timeout Errors: Increase the query timeout settings in the ODBC driver configuration.
  3. Data Not Appearing: Verify that the Athena query results are stored in the specified S3 bucket.

 

Conclusion

Integrating AWS Athena with Power BI allows businesses to leverage the scalability of AWS and the powerful analytics of Power BI. By following the steps outlined in this guide—from configuring AWS and Athena to setting up Power BI—you can seamlessly access, query, and visualize large datasets stored in Amazon S3.
