Hi, Thanks for the pull request. What's the difference between the publish/subscribe pattern and observer? |

I think the difference is that publish/subscribe is more loosely coupled and convenient, the subscriber can subscribe and unsubscribe anything they like. And normally we use publish/subscribe over the tcp/ip like redis. I simplified it to express it easily. |
