Should we expose _action_cable_internal as a constant?

[ioquatix]

Even thought it's kind of an internal detail, it's actually part of the public interface of Redis integration.

actioncable-next/lib/action_cable/subscription_adapter/redis.rb

Line 95 in f9c1c22

conn.subscribe("_action_cable_internal") do |on|

e.g.

CHANNEL = "_action_cable_internal"

[ioquatix]

To clarify a bit more, I think that my own implementation of the AsyncCableRedis adapter should use the same channel as it's going to be integrating with the same message bus.

Yeah, it's better to have it configurable, so you can run different apps attached to the same Redis without the overhead of processing the other app messages (even if you use channel_prefix you still invoke #broadcast in vain).
