2020/06/12 - AWS Glue - 5 updated api methods
Changes You can now choose to crawl the entire table or just a sample of records in DynamoDB when using AWS Glue crawlers. Additionally, you can also specify a scanning rate for crawling DynamoDB tables.
{'Crawlers': {'Targets': {'DynamoDBTargets': {'scanAll': 'boolean',
'scanRate': 'double'}}}}
Returns a list of resource metadata for a given list of crawler names. After calling the ListCrawlers operation, you can call this operation to access the data to which you have been granted permissions. This operation supports all IAM permissions, including permission conditions that uses tags.
