Summary: introduce new methods into a public threadpool interface, - allow submission of std::functions as they allow greater flexibility. - add Joining methods to the implementation to join scheduled and submitted jobs with an option to cancel jobs that did not start executing. - Remove ugly `#ifdefs` between pthread and std implementation, make it uniform. - introduce pimpl for a drop in replacement of the implementation - Introduce rocksdb::port::Thread typedef which is a replacement for std::thread. On Posix Thread defaults as before std::thread. - Implement WindowsThread that allocates memory in a more controllable manner than windows std::thread with a replaceable implementation. - should be no functionality changes.

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.
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/
