wait_objects_exist(paths: List[str], delay: Union[int, float, None] = None, max_attempts: Optional[int] = None, use_threads: bool = True, boto3_session: Optional[boto3.session.Session] = None) → None¶
Wait Amazon S3 objects exist.
Polls S3.Client.head_object() every 5 seconds (default) until a successful state is reached. An error is returned after 20 (default) failed checks. https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/s3.html#S3.Waiter.ObjectExists
In case of use_threads=True the number of threads that will be spawned will be get from os.cpu_count().

max_attempts (int, optional) – The maximum number of attempts to be made. Default: 20
