About Amazon Web Services (AWS) Athena

Amazon AWS Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. Athena is serverless, so there is no infrastructure to manage, and you pay only for the queries that you run.

AWS Athena Connector

The AWS Athena Connector enables Incorta to access files stored in an S3 bucket. Simply point to your data in Amazon S3, define the schema, and start querying using standard SQL.

The AWS Athena connector supports the following Incorta specific functionality:

Feature	Supported
Incremental Loading	✔
Encryption at Ingest
Performance Optimization	✔
Multi File Ingest	✔
Webhook Callbacks	✔
Remote Table Support	✔
