emit 0.3.0

Emitter for stream processing

Emit is a Python library for realtime data processing. It can distribute work with Celery or RQ, coordinate execution in other languages, and let you swing from the trees of your graph with Tarzan-like precision.

A taste:

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!

pip install emit
