+%description
+RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on
+earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
+
+This code is a library that forms the core building block for a fast key-value server, 
+especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database
+(LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), 
+Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded
+compactions, making it especially suitable for storing multiple terabytes of data in a single
+database.
