[docs]class S3CopyObjectOperator(BaseOperator):
"""
Creates a copy of an object that is already stored in S3.
Note: the S3 connection used here needs to have access to both
source and destination bucket/key.
:param source_bucket_key: The key of the source object. (templated)
It can be either full s3:// style url or relative path from root level.
When it's specified as a full s3:// url, please omit source_bucket_name.
:type source_bucket_key: str
:param dest_bucket_key: The key of the object to copy to. (templated)
The convention to specify `dest_bucket_key` is the same as `source_bucket_key`.
:type dest_bucket_key: str
:param source_bucket_name: Name of the S3 bucket where the source object is in. (templated)
It should be omitted when `source_bucket_key` is provided as a full s3:// url.
:type source_bucket_name: str
:param dest_bucket_name: Name of the S3 bucket to where the object is copied. (templated)
It should be omitted when `dest_bucket_key` is provided as a full s3:// url.
:type dest_bucket_name: str
:param source_version_id: Version ID of the source object (OPTIONAL)
:type source_version_id: str
:param aws_conn_id: Connection id of the S3 connection to use
:type aws_conn_id: str
:param verify: Whether or not to verify SSL certificates for S3 connection.
By default SSL certificates are verified.
You can provide the following values:
- False: do not validate SSL certificates. SSL will still be used,
but SSL certificates will not be
verified.
- path/to/cert/bundle.pem: A filename of the CA cert bundle to uses.
You can specify this argument if you want to use a different
CA cert bundle than the one used by botocore.
:type verify: bool or str
