Summary: In Zlib_Compress and BZip2_Compress the calculation for size was slightly off when using compression_foramt_version 2 (which includes the decompressed size in the output). Also there were unnecessary loops around the deflate/BZ2_bzCompress calls. In Zlib_Compress there was also a possible exit from the function after calling deflateInit2 that didn't call deflateEnd.

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.
