A wrapper around Cloud Storage's concept of an Object
.
name
str
The name of the blob. This corresponds to the unique path of the object in the bucket. If bytes, will be converted to a unicode object. Blob / object names can contain any sequence of valid unicode characters, of length 1-1024 bytes when UTF-8 encoded.
bucket
Bucket
The bucket to which this blob belongs.
chunk_size
int
(Optional) The size of a chunk of data whenever iterating (in bytes). This must be a multiple of 256 KB per the API specification. If not specified, the chunk_size of the blob itself is used. If that is not specified, a default value of 40 MB is used.
kms_key_name
str
(Optional) Resource name of Cloud KMS key used to encrypt the blob's contents.
generation
long
(Optional) If present, selects a specific revision of this object.
