Amazon Athena now supports managed query results, a significant quality-of-life improvement for users. This feature automatically manages the underlying S3 storage, eliminating manual cleanup and reducing costs since you no longer pay for S3 storage.

You Should Know:
How to Enable Managed Query Results in Athena
1. Open AWS Athena Console:
aws athena start-query-execution --query-string "SELECT FROM your_table" --result-configuration "OutputLocation=s3://your-bucket/"
2. Enable Managed Results in Settings:
- Navigate to Settings in the Athena console.
- Toggle “Use managed query results”.
3. Verify with AWS CLI:
aws athena get-work-group --work-group primary
Check for `”EnforceWorkGroupConfiguration”: true`.
4. Run a Test Query:
SELECT FROM cloudtrail_logs LIMIT 10;
Results will now be auto-managed.
Key AWS CLI Commands for Athena
- List recent queries:
aws athena list-query-executions --work-group primary
- Get query execution details:
aws athena get-query-execution --query-execution-id "your-query-id"
- Force cleanup (if needed):
aws s3 rm s3://athena-results-bucket/ --recursive
Automating Athena with Lambda
Use this Python snippet to trigger Athena queries:
import boto3
athena = boto3.client('athena')
response = athena.start_query_execution(
QueryString="SELECT FROM cloudtrail_logs",
WorkGroup="primary",
ResultConfiguration={'OutputLocation': 's3://athena-results/'}
)
print(response)
What Undercode Say:
Managed query results in Athena streamline data operations, reducing overhead for DevOps teams. This update aligns with AWS’s push for serverless efficiency. Expect more AI-driven query optimizations in future releases.
Expected Output:
{
"QueryExecutionId": "a1b2c3d4-5678-90ef-ghij-klmnopqrstuv",
"ResultConfiguration": {
"OutputLocation": "s3://aws-athena-managed-results-us-east-1-123456789012/"
},
"WorkGroup": "primary"
}
Prediction:
AWS will likely expand managed storage features to other services like Redshift and Glue, further reducing manual S3 management.
