How to create a global connection with asyncio and redis

I am new to python 3 and asyncio coming from gevent and 2.7 ....

How do I create a global connection that will be use by all for reids? E.g. I will have on 1 process e.g. 10 asyncio threads but I dont want a separate connection per thread. Why?..will have e.g. 100 cores with 10 threads per core and dont want that many connections to redis

import asyncio
import asyncio_redis

async def worker():
    while True:
        data = await connection.brpop(['queue'], timeout=0)
        print(data)
        res = blocking_code(data)
        await connection.set('test',res)

#Process raw data here and all code is blocking
def blocking_code(data):
    results = {}
    return results

if __name__ == '__main__':
    connection = asyncio_redis.Connection.create(host='127.0.0.1', port=6379, poolsize=2)
    loop = asyncio.get_event_loop()
    tasks = [asyncio.ensure_future(worker()), asyncio.ensure_future(worker())]
    loop.run_until_complete(asyncio.gather(*tasks))
    connection.close()


    Traceback (most recent call last):
      File "/Users//worker.py", line 14, in <module>
        loop.run_until_complete(example())
      File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/asyncio/base_events.py", line 466, in run_until_complete
        return future.result()
      File "/Users//worker.py", line 7, in example
        data = yield from connection.brpop(['queue'], timeout=0)
    AttributeError: 'generator' object has no attribute 'brpop'

So in the above I have two tasks but I want only 1 redis connection
