Download file from a received S3 path to local file.
In case of use_threads=True the number of threads that will be spawned will be gotten from os.cpu_count().
path (str) – S3 path (e.g.
local_file (Union[str, Any]) – A file-like object in binary mode or a path to local file (e.g.
version_id (Optional[str]) – Version id of the object.
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]]) – Forward to botocore requests, only “SSECustomerAlgorithm”, “SSECustomerKey” and “RequestPayer” arguments will be considered.
