AWS Glue PII检测作业花费太多时间。

【以下的问题经过翻译处理】 我有一个AWS Glue PII数据检测作业，对于17.9 MB的文件大小，完成需要大约47分钟，这对于任何spark作业来说都是非常长的时间。

以下是作业中使用的代码片段：

S3bucket_node1 = glueContext.create_dynamic_frame.from_options(
    format_options={
        "quoteChar": '"',
        "withHeader": True,
        "separator": ",",
        "optimizePerformance": False,
    },
    connection_type="s3",
    format="csv",
    connection_options={"paths": [f'{input_location}{file_name}']},
    transformation_ctx="S3bucket_node1",
)
# Script generated for node ApplyMapping
entity_detector = EntityDetector()
classified_map = entity_detector.classify_columns(
    S3bucket_node1,
    [
        "PERSON_NAME",
        "EMAIL",
        "CREDIT_CARD",
        "IP_ADDRESS",
        "MAC_ADDRESS",
        "PHONE_NUMBER",
        "USA_PASSPORT_NUMBER",
        "USA_SSN",
        "USA_ITIN",
        "BANK_ACCOUNT",
        "USA_DRIVING_LICENSE",
        "USA_HCPCS_CODE",
        "USA_NATIONAL_DRUG_CODE",
        "USA_NATIONAL_PROVIDER_IDENTIFIER",
        "USA_DEA_NUMBER",
        "USA_HEALTH_INSURANCE_CLAIM_NUMBER",
        "USA_MEDICARE_BENEFICIARY_IDENTIFIER",
        "JAPAN_BANK_ACCOUNT",
        "JAPAN_DRIVING_LICENSE",
        "JAPAN_MY_NUMBER",
        "JAPAN_PASSPORT_NUMBER",
        "UK_BANK_ACCOUNT",
        "UK_BANK_SORT_CODE",
        "UK_DRIVING_LICENSE",
        "UK_ELECTORAL_ROLL_NUMBER",
        "UK_NATIONAL_HEALTH_SERVICE_NUMBER",
        "UK_NATIONAL_INSURANCE_NUMBER",
        "UK_PASSPORT_NUMBER",
        "UK_PHONE_NUMBER",
        "UK_UNIQUE_TAXPAYER_REFERENCE_NUMBER",
        "UK_VALUE_ADDED_TAX",
        "CANADA_SIN",
        "CANADA_PASSPORT_NUMBER",
        "GENDER",
    ],
    1.0,
    0.55,
)

我还有Spark应用程序日志文件，但没法在这贴出。

这个作业的时间消耗这么大的根本原因是什么？
