based on levelDB, allows high performance on-disk bulk read/write.\n\nAllows async, multithreaded and/or remote access to a multi-leveldb backend.\n\nRelying on the zeromq network library and msgpack serialization format, it is made to be portable between languages and\nplatforms.\n\nSee `Documentation <http://oleiade.github.com/Elevator>`_ for more details\n\n\nDepends on\n----------\n\n- zmq-3.X\n- pyzmq (built with zmq-3.X)\n- leveldb\n- plyvel\n\n\nInstallation\n============\n\nThe easy way::\n\n    pip install elevator\n\nThe hacker way::\n\n    $ pip install fabric\n    $ fab build\n    $ pip install -r requirements.txt\n    $ python setup.py install\n\n\nUsage\n=====\n\nWhen elevator is installed, you can then launch the server using the elevator executable.\nNote that a --daemon option is disposable, and allows you to run elevator server as a daemon,\nstoring it's pid in ``.pid`` file in ``/tmp``.\n\nSee ``config/elevator.conf`` for an example of Elevator configuration.\n\n*Example*:\n\n.. code-block:: bash\n\n    $ elevator --help\n    usage: elevator -h\n\n    Elevator command line manager\n\n    optional arguments:\n        -h, --help       show this help message and exit\n        -d, --daemon      Launch elevator as a daemon\n        -c, --config      Path to elevator server config file, eventually\n        -t, --transport   Transfert protocol (tcp | ipc)\n        -b, --bind        Ip to bind server to\n        -p, --port        Port the server should listen on\n        -w, --workers     How many workers should be spawned (Threads with concurrent access to all the db store)\n        -P, --paranoid    If option is set, Elevator will shutdown and log on first unhandled exception\n\n\nClients\n=======\n\n*Python*: `py-elevator <http://github.com/oleiade/py-elevator>`_\n\n*Go*: `go-elevator <http://github.com/oleiade/go-elevator>`_ (Early early, so early version)\n\n*Clojure* : *Coming soon*\n\n*C* : *Coming soon*\n\n\nThanks\n======\n\nThanks to `srinikom <https://github.com/srinikom>`_ for its `leveldb-server <https://github.com/srinikom/leveldb-server>`_ which was a very good base to start from.\n\n\n\nn.n.n / 2013-02-01 \n==================\n\n  * Remove: legacy setup_loggers function\n  * fix #123: exposing a database object\n  * ref #123: Renamed DatabasesHandler to DatabaseStore\n
