2020/10/21 - AWS Glue - 5 updated api methods
Changes AWS Glue crawlers now support incremental crawls for the Amazon Simple Storage Service (Amazon S3) data source.
{'Crawlers': {'RecrawlPolicy': {'RecrawlBehavior': 'CRAWL_EVERYTHING | '
'CRAWL_NEW_FOLDERS_ONLY'}}}
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.

string
[REQUIRED]
Name of the new crawler.
string
The IAM role or Amazon Resource Name (ARN) of an IAM role that is used by the new crawler to access customer resources.
string
The AWS Glue database where results are stored, such as: arn:aws:daylight:us-east-1::database/sometable/* .
string
A description of the new crawler.
dict
A list of targets to crawl.
S3Targets (list) --
Specifies Amazon Simple Storage Service (Amazon S3) targets.
(dict) --
Specifies a data store in Amazon Simple Storage Service (Amazon S3).
Path (string) --
The path to the Amazon S3 target.
Exclusions (list) --
A list of glob patterns used to exclude from the crawl. For more information, see Catalog Tables with a Crawler .
(string) --
ConnectionName (string) --
The name of a connection which allows a job or crawler to access data in Amazon S3 within an Amazon Virtual Private Cloud environment (Amazon VPC).
JdbcTargets (list) --
Specifies JDBC targets.
(dict) --
Specifies a JDBC data store to crawl.
ConnectionName (string) --
The name of the connection to use to connect to the JDBC target.
Path (string) --
The path of the JDBC target.
Exclusions (list) --
A list of glob patterns used to exclude from the crawl. For more information, see Catalog Tables with a Crawler .
(string) --
MongoDBTargets (list) --
Specifies Amazon DocumentDB or MongoDB targets.
(dict) --
Specifies an Amazon DocumentDB or MongoDB data store to crawl.
ConnectionName (string) --
The name of the connection to use to connect to the Amazon DocumentDB or MongoDB target.
Path (string) --
The path of the Amazon DocumentDB or MongoDB target (database/collection).
ScanAll (boolean) --
Indicates whether to scan all the records, or to sample rows from the table. Scanning all the records can take a long time when the table is not a high throughput table.
A value of true means to scan all records, while a value of false means to sample the records. If no value is specified, the value defaults to true .
DynamoDBTargets (list) --
Specifies Amazon DynamoDB targets.
(dict) --
Specifies an Amazon DynamoDB table to crawl.
Path (string) --
The name of the DynamoDB table to crawl.
scanAll (boolean) --
Indicates whether to scan all the records, or to sample rows from the table. Scanning all the records can take a long time when the table is not a high throughput table.
A value of true means to scan all records, while a value of false means to sample the records. If no value is specified, the value defaults to true .
scanRate (float) --
The percentage of the configured read capacity units to use by the AWS Glue crawler. Read capacity units is a term defined by DynamoDB, and is a numeric value that acts as rate limiter for the number of reads that can be performed on that table per second.
The valid values are null or a value between 0.1 to 1.5. A null value is used when user does not provide a value, and defaults to 0.5 of the configured Read Capacity Unit (for provisioned tables), or 0.25 of the max configured Read Capacity Unit (for tables using on-demand mode).
