redis处理'N'没有连接的能力？

Question

如果使用Redis进行任何性能测量 它可以处理多少个同时订阅/频道？

Answer 1

我还没有看到这方面的基准，但推动订阅频道的复杂性在于O（N）系列。 来自文档：

PUBLISH：

O(N+M) where N is the number of clients subscribed to the
receiving channel and M is the total number of subscribed 
patterns (by any client).

PSUBSCRIBE（订阅模式）：

O(N) where N is the number of patterns the client is already subscribed to.

SUBSCRIBE：

O(N) where N is the number of channels to subscribe to.
