Display NameAPI NameDefault ValueAllowable ValuesDescription
Parameter Group Directoriesparameter-group-directoriesA comma-separated list of directory absolute paths that will map to named parameter groups.

Files inside the directory will map to parameter names, whose values are the content of each respective file.
Parameter Value Byte Limitparameter-value-byte-limit256 BThe maximum byte size of a parameter value. Since parameter values are pulled from the contents of files, this is a safeguard that can prevent memory issues if large files are included.
