This is a read-only inventory tool for mapping your AWS data landscape across Glue Data Catalog, S3 Tables, and federated sources like Redshift or remote Iceberg catalogs. It walks you through catalogs, databases, and tables without executing queries, which keeps scope tight but means you'll need a different skill when you actually want to query something. The routing logic is smart: feed it an S3 path, catalog name, database, table, or search term and it figures out what you meant. Particularly useful detail: it flags S3 Tables that exist in the API but aren't registered in Glue, so they're invisible to Athena. If you inherit a messy AWS account, this gives you the map.
