gremlinclient

gremlinclient is an asynchronous multi-client Python driver for the TinkerPop 3 Gremlin Server. By default, it uses the Tornado websocket client implementation to communicate with the server, but it also supports aiohttp for a pure Asyncio implementation–support for Pulsar and requests-futures coming soon.

Releases

The latest release of gremlinclient is 0.2.6.

Requirements

gremlinclient with Tornado requires Python 2.7+. That said, there are a variety of client/library combinations that work with different versions of Python.

Tornado

  • Python 2.7+

Tornado w/Asyncio

  • Python 3.3+

Tornado w/Trollius

  • Python 2.7

aiohttp

  • Python 3.4+

Installation

Install using pip:

$ pip install gremlinclient

Getting Started

Submit a script to the Gremlin Server with Python 2.7 or 3.3+ using Tornado:

>>> from tornado import gen
>>> from tornado.ioloop import IOLoop
>>> from gremlinclient.tornado_client import submit

>>> loop = IOLoop.current()

>>> @gen.coroutine
... def go():
...     resp = yield submit("ws://localhost:8182/", "1 + 1")
...     while True:
...         msg = yield resp.read()
...         if msg is None:
...             break
...         print(msg)
>>> loop.run_sync(go)

Message(status_code=200, data=[2], message=u'', metadata={})
