Defining crawlers in Amazon Glue

You can use a crawler to populate the Amazon Glue Data Catalog with tables. This is the primary method used by most Amazon Glue users. A crawler can crawl multiple data stores in a single run. Upon completion, the crawler creates or updates one or more tables in your Data Catalog. Extract, transform, and load (ETL) jobs that you define in Amazon Glue use these Data Catalog tables as sources and targets. The ETL job reads from and writes to the data stores that are specified in the source and target Data Catalog tables.
