Yes, Superset supports handling S3 tables in AWS Athena. To ensure proper configuration, you need to set specific environment variables and feature flags:
Environment Variables:
- `SUPERSET_REGION`: Set this to your AWS region, e.g., `eu-west-1`.
- `SUPERSET_WORKGROUP`: Set this to your Athena workgroup, e.g., `superset-etl`.
- `SUPERSET_ATHENA_DB`: Set this to your Athena database name, e.g., `my_superset_db`.
Feature Flags:
- `DownloadCSVFromS3`: Enable this feature flag (`DOWNLOAD_CSV_FROM_S3`).
- `ShowDefaultCSVOptions`: Enable this feature flag (`SHOW_DEFAULT_CSV_OPTIONS`) <sup>[[1]](https://github.com/apache/superset/issues/31482)</sup>.
Additionally, ensure that your connection string is correctly formatted and includes all necessary parameters. The format should be:
```
awsathena+rest://{aws_access_key_id}:{aws_secret_access_key}@athena.{region_name}.amazonaws.com/{schema_name}?s3_staging_dir={s3_staging_dir}&...
```
If you are experiencing schema visibility issues, common causes include incorrect schema names or insufficient permissions. Verify that the schema exists and that your user account has the necessary permissions <sup>[[2]](https://github.com/apache/superset/blob/master/docs/docs/using-superset/issue-codes.mdx)</sup><sup>[[3]](https://github.com/apache/superset/blob/master/superset/errors.py)</sup>.
