response = client.list_crawls(
    CrawlerName='string',
    MaxResults=123,
    Filters=[
        {
            'FieldName': 'CRAWL_ID'|'STATE'|'START_TIME'|'END_TIME'|'DPU_HOUR',
            'FilterOperator': 'GT'|'GE'|'LT'|'LE'|'EQ'|'NE',
            'FieldValue': 'string'
        },
    ],
    NextToken='string'
)
Parameters:

  • CrawlerName (string) –

    [REQUIRED]

  • MaxResults (integer) – The maximum number of results to return. The default is 20, and maximum is 100.

  • Filters (list) –

    Filters the crawls by the criteria you specify in a list of CrawlsFilter objects.

    • (dict) –

      A list of fields, comparators and value that you can use to filter the crawler runs for a specified crawler.

      • FieldName (string) –

        A key used to filter the crawler runs for a specified crawler. Valid values for each of the field names are:

        • CRAWL_ID: A string representing the UUID identifier for a crawl.

        • STATE: A string representing the state of the crawl.

        • START_TIME and END_TIME: The epoch timestamp in milliseconds.

        • DPU_HOUR: The number of data processing unit (DPU) hours used for the crawl.

      • FilterOperator (string) –

        A defined comparator that operates on the value. The available operators are:

        • GT: Greater than.

        • GE: Greater than or equal to.

        • LT: Less than.

        • LE: Less than or equal to.

        • EQ: Equal to.

        • NE: Not equal to.

      • FieldValue (string) –

        The value provided for comparison on the crawl field.

  • NextToken (string) – A continuation token, if this is a continuation call.

Return type:
