Analytics

Amazon Athena

Serverless interactive SQL query service for data in Amazon S3 and supported data sources.

Key points

  • Queries data without provisioning a database server.
  • DVA-C02 requires only narrow data-query recognition because no numbered skill names Athena.

Best-known use cases

  • Ad hoc SQL over S3 objects.

What candidates often confuse it with

  • Athena queries data in place; OpenSearch Service provides indexed search and analytics.

Key takeaway

Recognize Athena as serverless SQL over S3, not as the default application transaction store.

Related services

  • Amazon S3
  • Amazon OpenSearch Service

Relevant exam tasks

  • D1.3 — Use data stores in application development
  • 1.3.9 — Use specialized data stores based on access patterns (for example, Amazon OpenSearch Service)
