AWS Glue Crawler

A Glue component that scans data stores, infers schemas and partitions, and creates or updates tables in the Data Catalog.

Definition

Crawlers can run on a schedule or on events. Alternatives for adding new partitions include partition projection in Athena and MSCK REPAIR TABLE.

Exam tip

New S3 partitions are invisible to Athena until a crawler, MSCK REPAIR or partition projection registers them.
