Indicates the size of the object.
Indicates the ETag of the object, which is generated when an object is created to identify the content of the object.
For an object created by a PutObject request, its ETag is the MD5 value of its content. For an object created in other methods, its ETag is the UUID of its content. The ETag of an object can be used to check whether the content of the object changes. We recommend you do not use ETag as the MD5 value of an object to verify data integrity.
