easy to use redis(kb)

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
from easy_redis.redis_consumer import EasyRedisConsumer

def start_consumer():
    redis_consumer = EasyRedisConsumer('../conf/conf.yml')
    print('consumer iterator started')
    for record in redis_consumer:
        if record['type'] == 'message':
            print('data', json.loads(record['data']))
        else:
            print('subscribe', record)

if __name__ == "__main__":
    start_consumer()

3.demo-consumer-task

import json

from easy_redis.redis_consumer import EasyRedisConsumer
from easy_redis.redis_producer import EasyRedisProducer

redis_producer = EasyRedisProducer('../conf/conf.yml')


def consumer_task(record):
    """
    consumer callback
    :param record: object
    :return:
    """
    print('consumer_task', (
        'received type: {}, channel: {}, msg: {}'.format(record['type'], record['channel'], record['data'])))
    if record['type'] == 'message':
        print('data', json.loads(record['data']))
    if record['channel'] == 'channel_1':
        redis_producer.produce_msg({'type': 'task result'})


def start_consumer():
    redis_consumer = EasyRedisConsumer('../conf/conf.yml')
    print('consumer task started')
    redis_consumer.subscribe(fn=consumer_task)


if __name__ == "__main__":
    start_consumer()

4.demo-producer
