+key-value server, especially suited for storing data on flash drives.  It
+has a @dfn{Log-Structured-Merge-Database} (LSM) design with flexible tradeoffs
+between @dfn{Write-Amplification-Factor} (WAF), @dfn{Read-Amplification-Factor}
+(RAF) and @dfn{Space-Amplification-Factor} (SAF).  It has multi-threaded
+compactions, making it specially suitable for storing multiple terabytes of
+data in a single database.  RocksDB is partially based on @code{LevelDB}.")
