A Glue crawler discovers an S3 dataset and creates a table in the Glue Data Catalog. A stakeholder assumes the data has now been copied into the catalog. Which explanation is correct?

1. The crawler always deletes the original objects after copying every row into the catalog.
2. The catalog stores metadata such as schema and location; the underlying objects remain in S3 unless a separate processing step moves them.
3. The crawler guarantees all discovered records satisfy every business data-quality rule.
4. The catalog automatically creates a Redshift cluster and loads all discovered data.
