> Assignee: Jing Zhao

> Currently each INodeDirectorySection.Entry contains variable numbers of
> INodeReference entries. The INodeReference entries are inlined, therefore it
> is difficult to quickly navigate through a INodeDirectorySection.Entry.
> Skipping through a INodeDirectorySection.Entry without parsing is essential
> to parse these entries in parallel.
> This jira proposes to consolidate INodeReferences into a section and give
> each of them an ID. The INodeDirectorySection.Entry can store the list of the
> IDs as a repeated field. That way we can leverage the existing code in
> protobuf to quickly skip through a INodeDirectorySection.Entry.
