Objects stored on GCS are identified by a pathname of up to 1024 Unicode characters. The GCS CLI and GUI will segregate the display of objects into what “appear” to be directories if forward slashes are present in the names. However, this is a display convenience, and directories do not need to be created. You may pick your object names with or without slashes, as is convenient for your application.
To simplify scripting, the following API provides for two strings which will be concatenated to define the object pathname. The Prefix string is optional, but may simplify scripting by allowing the Object string to be something very simple and short, like the name of the table.
