:target: http://elevator.readthedocs.org
Key-Value store written in Python and based on levelDB, allows high performance on-disk bulk read/write.
Allows async, multithreaded and/or remote access to a multi-leveldb backend.
Relying on the zeromq network library and msgpack serialization format, it is made to be portable between languages and
platforms.
See `Documentation <http://oleiade.github.com/Elevator>`_ for more details
Depends on
----------
- zmq-3.X
- pyzmq (built with zmq-3.X)
- leveldb
- plyvel
Installation
============
The easy way::
pip install elevator
The hacker way::
$ pip install fabric
$ fab build
$ pip install -r requirements.txt
$ python setup.py install
Usage
=====
When elevator is installed, you can then launch the server using the elevator executable.
Note that a --daemon option is disposable, and allows you to run elevator server as a daemon,
storing it's pid in ``.pid`` file in ``/tmp``.
See ``config/elevator.conf`` for an example of Elevator configuration.
*Example*:
.. code-block:: bash
$ elevator --help
usage: elevator -h
Elevator command line manager
optional arguments:
-h, --help show this help message and exit
-d, --daemon Launch elevator as a daemon
-c, --config Path to elevator server config file, eventually
-t, --transport Transfert protocol (tcp | ipc)
-b, --bind Ip to bind server to
-p, --port Port the server should listen on
-w, --workers How many workers should be spawned (Threads with concurrent access to all the db store)
-P, --paranoid If option is set, Elevator will shutdown and log on first unhandled exception
