Response Structure
(dict) --
Crawlers (list) --
A list of crawler metadata.
(dict) --

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.
Targets (dict) --
A collection 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.
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).
SampleSize (integer) --
Sets the number of files in each leaf folder to be crawled when crawling sample files in a dataset. If not set, all the files are crawled. A valid value is an integer between 1 and 249.
EventQueueArn (string) --
A valid Amazon SQS ARN. For example, arn:aws:sqs:region:account:sqs .
DlqEventQueueArn (string) --
A valid Amazon dead-letter SQS ARN. For example, arn:aws:sqs:region:account:deadLetterQueue .
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.
EnableAdditionalMetadata (list) --
Specify a value of RAWTYPES or COMMENTS to enable additional metadata in table responses. RAWTYPES provides the native-level datatype. COMMENTS provides comments associated with a column or table in the database.
If you do not need additional metadata, keep the field empty.
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 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).
CatalogTargets (list) --
Specifies Glue Data Catalog targets.
(dict) --
Specifies an Glue Data Catalog target.
DatabaseName (string) --
The name of the database to be synchronized.
Tables (list) --
A list of the tables to be synchronized.
ConnectionName (string) --
The name of the connection for an Amazon S3-backed Data Catalog table to be a target of the crawl when using a Catalog connection type paired with a NETWORK Connection type.
EventQueueArn (string) --
A valid Amazon SQS ARN. For example, arn:aws:sqs:region:account:sqs .
DlqEventQueueArn (string) --
A valid Amazon dead-letter SQS ARN. For example, arn:aws:sqs:region:account:deadLetterQueue .
DeltaTargets (list) --
Specifies Delta data store targets.
(dict) --
Specifies a Delta data store to crawl one or more Delta tables.
DeltaTables (list) --
A list of the Amazon S3 paths to the Delta tables.
ConnectionName (string) --
The name of the connection to use to connect to the Delta table target.
WriteManifest (boolean) --
Specifies whether to write the manifest files to the Delta table path.
CreateNativeDeltaTable (boolean) --
Specifies whether the crawler will create native tables, to allow integration with query engines that support querying of the Delta transaction log directly.
DatabaseName (string) --
The name of the database in which the crawler's output is stored.
Description (string) --
A description of the crawler.
Classifiers (list) --
A list of UTF-8 strings that specify the custom classifiers that are associated with the crawler.
RecrawlPolicy (dict) --
A policy that specifies whether to crawl the entire dataset again, or to crawl only folders that were added since the last crawler run.
RecrawlBehavior (string) --
Specifies whether to crawl the entire dataset again or to crawl only folders that were added since the last crawler run.
A value of CRAWL_EVERYTHING specifies crawling the entire dataset again.
A value of CRAWL_NEW_FOLDERS_ONLY specifies crawling only folders that were added since the last crawler run.
A value of CRAWL_EVENT_MODE specifies crawling only the changes identified by Amazon S3 events.
SchemaChangePolicy (dict) --
The policy that specifies update and delete behaviors for the crawler.
UpdateBehavior (string) --
The update behavior when the crawler finds a changed schema.
DeleteBehavior (string) --
The deletion behavior when the crawler finds a deleted object.

Indicates whether the crawler is running, or whether a run is pending.
TablePrefix (string) --
The prefix added to the names of tables that are created.
Schedule (dict) --
For scheduled crawlers, the schedule when the crawler runs.
ScheduleExpression (string) --
A cron expression used to specify the schedule (see Time-Based Schedules for Jobs and Crawlers. For example, to run something every day at 12:15 UTC, you would specify: cron(15 12 * * ? *) .
State (string) --
The state of the schedule.
CrawlElapsedTime (integer) --
If the crawler is running, contains the total time elapsed since the last crawl began.

MessagePrefix (string) --
The prefix for a message about this crawl.
StartTime (datetime) --
The time at which the crawl started.
