Pluggable storage?

Hi,

Was just reading about SSTable and LevelDB (http://www.igvita.com/2012/02/06/sstable-and-log-structured-storage-leveldb/), which has some HBase references.  Somebody pointed out in comments Riak supports LevelDB as a storage engine option, which made me wonder whether pluggable backend storage is on HBase's long-term road map?

Thanks,
Otis

No one seems to be calling for it Otis.  I think we're still working
on our current storage trying to make sense of it under the different
loadings.  What would you want?  Leveldb is attractive because its
'done' but it would seem to make for significantly more i/o spent at
compaction time (though at read time there could be less).
