Are you actually prepared to undertake all of the measurement and tuning 
required to make RocksDB actually work well? You're switching from an 
(abandoned/unsupported) engine with only a handful of config parameters to one 
with ~40-50 params, all of which have critical but unpredictable impact on 
resource consumption and performance.
