Not required, certainly.  However, it strikes me that 1 cluster is better
than 2, and most consumers of a filesystem would expect to be able to get an
ordered listing or tree of the metadata which is easy using the OPP row key
pattern listed previously.  You could still do this with the Random
partitioner using column names in rows to describe the structure but the
current compaction limitations could be an issue if a branch becomes too
large, and you'd still have a root row hotspot (at least in the schema which
comes to mind).
