Jay Edgar 15b7a4ab88 Fixed output size and removed unneeded loop 
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

Build Status

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.

Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples

See the github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.

Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/
