I’m curious about how Phoenix Channels are implemented. Is it gauranteed that all connections to a topic is to the same server?

No.

@zizheng

If not, how does Phoenix solve the problem of having to forward messages of one user on a topic to the other users on the topic?

The receiving server will forward the message to all other servers. Each server will check on its own whether or not it has someone registered to that topic or not and drop or distribute the message accordingly.

@zizheng

Does it need to forward the messages first between different servers?

Of course…
