Message persistence - Redis pub/sub

Question

A message published on a channel is received by subscribers at the other end. However, if no active subscriber is found the message is simply lost.

And here is my question, is it possible to modify Redis to support message persistence when subscriber is no active?

Answer 1

不，没有-消息在发布时被发送给所有订阅者（如果有的话），并且不持久。
