> A Zebra table is stored as multiple sub tables each containing a set of
> columns called column group (CG). The user specifies how these columns are
> grouped while creating a table through the _storage hint_.
> For some of the large tables, it might be necessary for users to remove a set
> of columns and retain the rest. This jira provides a way for users to delete
> an entire column group.
> The following comments will have more details on API and the semantics.
