1.2.9 Extended Attributes
A user-defined extended attribute is non-standard metadata that is associated with an Exascale vault or file. An extended attribute consists of an extended attribute name and associated value. The extended attribute name is a string value that the user chooses. The extended attribute value can be a string value, or a binary value that is read from a file.
Multiple extended attributes are allowed for each Exascale vault or file. For each file or vault, the total available space for all extended attributes is 16 kilobytes, including the extended attribute names and values, along with an allowance for internal metadata.
Extended attributes with names that start with a dollar sign ($
) are
reserved for internal use by Exascale services and
tools. You cannot create, modify, or delete these extended attributes.
