easy_redis
^^^^^^^^^^
Easy to use python redis(for kb first)

Compared with kafka, redis has the following characteristics in publishing and subscribing:

* Produced messages are immediately consumed by consumers.
* Fast speed, small data( < 10KB).
* Allow message loss.
* No need to save sent messages.

Quick Start
-----------
**Installation**: pip install easy_redis

1.config
>>>>>>>>
Edit conf/conf.yml
::

    redis: # redis config
      server: 127.0.0.1 # redis server
      port: 6379
      channel_subscribe: # channel if need, multiple
        - channel_1
        - channel_2
      channel_produce: channel_1_result # producer default channel

2.demo-consumer
>>>>>>>>>>>>>>>>>>
::

    import json

        for record in redis_consumer:
            if record['type'] == 'message':
                print('data', json.loads(record['data']))
            else:
                print('subscribe', record)
