更新现有的批量数据

要更新批量数据，请使用 create_dataset_import_job 方法。对于 import-mode，指定 FULL 以替换现有数据，或者指定 INCREMENTAL 以向其中添加数据。有关更多信息，请参阅导入模式。

import boto3

personalize = boto3.client('personalize')

response = personalize.create_dataset_import_job(
    jobName = 'YourImportJob',
    datasetArn = 'dataset_arn',
    dataSource = {'dataLocation':'s3://bucket/file.csv'},
    roleArn = 'role_arn',
    importMode = 'INCREMENTAL'
)

要更新批量数据，请使用以下 createPersonalizeDatasetImportJob 方法。对于 importImport，指定 ImportMode.FULL 以替换现有数据，或者指定 ImportMode.INCREMENTAL 以向其中添加数据。有关更多信息，请参阅导入模式。
