Using Athena SQL with external Iceberg REST Catalog

Question

I have an external Iceberg REST Catalog implementation and I need to use that with Athena. Do we currently support this use case? If so, are there any documentation on how to do this? 
The closest use case that I could find is how Tabular integrates with Athena SQL. https://docs.tabular.io/athena

### I have an external Iceberg REST Catalog implementation and I need to use that with Athena. Do we currently support this use case?
Yes, using an external Iceberg REST Catalog with Amazon Athena is supported through the integration capabilities provided by AWS, specifically designed for Apache Iceberg tables. This setup allows Athena to interact with Iceberg tables managed by external catalogs, enabling a wide range of data analytics operations directly on your data lake.

Check here for more information: 
- [Using Apache Iceberg tables](https://docs.aws.amazon.com/athena/latest/ug/querying-iceberg.html)
- [Decoupling Using the REST Catalog](https://iceberg.apache.org/concepts/catalog/#decoupling-using-the-rest-catalog)

Answer

Thanks. Does that mean, I need to go on the route of creating data sources using a new Lambda function?
