awswrangler.s3.copy_objects

awswrangler.s3.copy_objects(paths: List[str], source_path: str, target_path: str, replace_filenames: Optional[Dict[str, str]] = None, use_threads: Union[bool, int] = True, boto3_session: Optional[Session] = None, s3_additional_kwargs: Optional[Dict[str, Any]] = None) → List[str]

Copy a list of S3 objects to another S3 directory.

Note

In case of use_threads=True the number of threads that will be spawned will be gotten from os.cpu_count().

Parameters

  • paths (List[str]) – List of S3 objects paths (e.g. [s3://bucket/dir0/key0, s3://bucket/dir0/key1]).

  • source_path (str,) – S3 Path for the source directory.

  • target_path (str,) – S3 Path for the target directory.

  • replace_filenames (Dict[str, str], optional) – e.g. {“old_name.csv”: “new_name.csv”, “old_name2.csv”: “new_name2.csv”}

  • use_threads (bool, int) – True to enable concurrent requests, False to disable multiple threads. If enabled os.cpu_count() will be used as the max number of threads. If integer is provided, specified number is used.

  • boto3_session (boto3.Session(), optional) – Boto3 Session. The default boto3 session will be used if boto3_session receive None.

  • s3_additional_kwargs (Optional[Dict[str, Any]]) – Forwarded to botocore requests. e.g. s3_additional_kwargs={‘ServerSideEncryption’: ‘aws:kms’, ‘SSEKMSKeyId’: ‘YOUR_KMS_KEY_ARN’}

Returns

List of new objects paths.

Return type

List[str]
