AWS Glue crawler is used to connect to a data store, progresses done through a priority list of the classifiers used to extract the schema of the data and other statistics, and inturn populate the Glue Data Catalog with the help of the metadata. Crawlers also run periodically that will detect the availability of the new data also with the change to the existing data, including the table definition changes made by the data crawler. Crawlers automatically adds new table, new partitions to the existing table and the new versions of table definitions. You can also customize the Glue crawlers to classify your file types.
