Summary: This diff merges pull request #208. Contributor: ankgup87 [Java] Optimize statistics collector * Optimize statistics collector by collecting statistics of multiple DBs in a single thread rather than starting up a new thread for each DB. * Also, fix packaging of jnilib file on OS_X platform. * Diff review: https://reviews.facebook.net/D20265 [Java] Add documentation on interdependency of dispose call of RocksObjects * Remove transferCppRawPointersOwnershipFrom function. - This function was setting opt.filter_ and thus filter_ to be null. This way there is no one holding reference for filter object and can thus be GC'd which is not the intention. Replaced it with storeOptionsInstace which stores options instance. Options class internally holds Filter instance. Thus when Options is GC'd, filter reference will be GC'd automatically. * Added documentation explaining interdependency of Filter, Options and DB. * Diff review: https://reviews.facebook.net/D20379 Test Plan: described in their diff reviews Reviewers: haobo sdong swapnilghike zzbennett rsumbaly yhchiang Reviewed by: yhchiang |

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 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.

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.
