rocksdb Seen today - replacement for leveldb?

Hi,

while googles leveldb was too slow for facebook they created rocksdb
(http://rocksdb.org/) may be interesting for Ceph? It's already
production quality.

Greets,

Very interesting guys!  I'm also interested in sync reads/writes. 
That's where leveldb really seemed to fall over in the testing I did. 
On my laptop with an SSD I was getting 200 iops no matter if I was doing 
random or sequential sync writes (using a single thread) with stock 
leveldb, hyperdex, or basho's version.  It would be interesting to try 
rocksdb.

Nisha Talagala of Fusion IO also did a presentation at PDSW comparing 
their OpenNVM key-value layer to leveldb for sync reads/writes here 
(slide 24):
