RocksDB vs. the world

I'd be very interested in seeing a comparison between storage engines like rocks, wiredtiger, leveldb, sqlite4-lsm, heck even kyotocabinet and berkeleydb. The comparison would describe what workload each storage engine optimizes for, what tradeoffs were made, and a basic feature matrix (multiple process? transactions / nested transactions? etc).

There are a lot of options out there but beyond pure speed or latency measures, its hard to get a high level understanding of what distinguishes one storage engine from the next.

So... we should all move to MySQL+Rocks?

Sounds like it's 2005 all over again!
