Athena
Athena lets you use SQL queries to find data stored in S3. If you have data stored in CSV, JSON, ORC, Avro, or Parquet format, simply upload it to S3 and use Athena to query it. Athena is serverless, so there’s no need to provision your own database or import your data into it. For more information, visit https://aws.amazon.com/athena/.
