> Regex Link Type In Mont Table-V0.pdf
>
>
> This jira is created to support regex based mount point in Inode Tree. We
> noticed that mount point only support fixed target path. However, we might
> have user cases when target needs to refer some fields from source. e.g. We
> might want a mapping of /cluster1/user1 => /cluster1-dc1/user-nn-user1, we
> want to refer `cluster` and `user` field in source to construct target. It's
> impossible to archive this with current link type. Though we could set
> one-to-one mapping, the mount table would become bloated if we have thousands
> of users. Besides, a regex mapping would empower us more flexibility. So we
> are going to build a regex based mount point which target could refer groups
> from src regex mapping.
