Creates, updates, deletes or gets a crawler resource or lists crawlers in a region

Overview

Name	crawlers
Type	Resource
Description	Resource Type definition for AWS::Glue::Crawler
Id	aws.glue.crawlers

Fields

Name	Datatype	Description
classifiers	array	A list of UTF-8 strings that specify the names of custom classifiers that are associated with the crawler.
description	string	A description of the crawler.
schema_change_policy	object	The policy that specifies update and delete behaviors for the crawler. The policy tells the crawler what to do in the event that it detects a change in a table that already exists in the customer's database at the time of the crawl. The SchemaChangePolicy does not affect whether or how new tables and partitions are added. New tables and partitions are always created regardless of the SchemaChangePolicy on a crawler. The SchemaChangePolicy consists of two components, UpdateBehavior and DeleteBehavior.
configuration	string	Crawler configuration information. This versioned JSON string allows users to specify aspects of a crawler's behavior.
recrawl_policy	object	When crawling an Amazon S3 data source after the first crawl is complete, specifies whether to crawl the entire dataset again or to crawl only folders that were added since the last crawler run. For more information, see Incremental Crawls in AWS Glue in the developer guide.
database_name	string	The name of the database in which the crawler's output is stored.
targets	object	Specifies data stores to crawl.
crawler_security_configuration	string	The name of the SecurityConfiguration structure to be used by this crawler.
name	string	The name of the crawler.
role	string	The Amazon Resource Name (ARN) of an IAM role that's used to access customer resources, such as Amazon Simple Storage Service (Amazon S3) data.
lake_formation_configuration	object	Specifies AWS Lake Formation configuration settings for the crawler
schedule	object	A scheduling object using a cron statement to schedule an event.
table_prefix	string	The prefix added to the names of tables that are created.
tags	object	The tags to use with this crawler.
region	string	AWS region.

For more information, see AWS::Glue::Crawler.
