Documentation

Specifies a crawler program that examines a data source and uses classifiers to try to determine its schema. If successful, the crawler records metadata concerning the data source in the Glue Data Catalog.

See: newCrawler smart constructor.

$sel:state:Crawler', crawler_state - Indicates whether the crawler is running, or whether a run is pending.

$sel:schemaChangePolicy:Crawler', crawler_schemaChangePolicy - The policy that specifies update and delete behaviors for the crawler.

$sel:lastUpdated:Crawler', crawler_lastUpdated - The time that the crawler was last updated.

$sel:schedule:Crawler', crawler_schedule - For scheduled crawlers, the schedule when the crawler runs.

$sel:lastCrawl:Crawler', crawler_lastCrawl - The status of the last crawl, and potentially error information if an error occurred.
