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).
