pypi i emit



Emit is a Python library for realtime data processing. It can distribute work with Celery <https://emit.readthedocs.org/en/latest/distributing-work/celery.html> or RQ <https://emit.readthedocs.org/en/latest/distributing-work/rq.html>, coordinate execution in other languages <https://emit.readthedocs.org/en/latest/multilang.html>_, and let you swing from the trees of your graph with Tarzan-like precision.

A taste:

.. code:: python

from emit import router

router = Router()

@router.node(['word'], entry_point=True)
def parse_document(msg):
    for word in msg.document.strip().split(' '):
        yield word

@router.node(['word', 'count'], 'parse_document')
def count_word(msg):
    return msg.word, redis.zincrby('word_counts', msg.word, 1)

import random
document = 'the words in this document will be counted and emitted by count_word'.split(' ')
router(document=' '.join(random.choice(document) for i in range(20)))

So how do you get it? On PyPI!

Installing from source/development branch:

Emit's releases are fairly frequent, so you should be good to use a released version. However, if you need something currently not in a version, try the develop branch::

pip install git+git://github.com/BrianHicks/emit.git@develop

Just do be warned that things will break. And be sure to check Travis <https://travis-ci.org/BrianHicks/emit>__ to see if the platform you want is currently passing. It should be, but maybe not.
