Summary: Add the flag --prefix to the sst_dump tool This flag is similar to, and exclusive from, the --from flag. --prefix=0x00FF will return all rows prefixed with 0x00FF. The --to flag may also be specified and will work as expected. These changes were used to help in debugging the power cycle corruption issue and theses changes were tested by scanning through a udb.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
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 specially suitable for storing multiple terabytes of data in a single database.
