Publish on multiple channels doesn't work about ruby HOT 4 CLOSED

Hi. The backend service doesn't support publishing a message to multiple channels simultaneously. It would have to be implemented in the client SDK by looping through the channel list.

from ruby.

Samnang,
Something I did in the past using the Java SDK was to create a publisher worker thread that will publish to a specific channel. Each of those publishers will subscribe to a single master worker thread that will publish the message to those channel specific publishers which will in turn publish the message to their own channels. This is a good design pattern if it needs to be publish to all channels at the same time rather than in sequence.

To be more specific:

• Master worker thread publishes a message on channel_master
• Channel 1 worker thread subscribes to channel_master and publishes message received on channel1
• Channel 2 worker thread subscribes to channel_master and publishes message received on channel2
  ...
• Channel n worker thread subscribes to channel_master and publishes message received on channelN

What I try to build is private messaging between users in social mobile
application. A user can select one or few users to send messages back and
forth between them like Facebook. I'm not a good design pattern yet, but so
far I got whenever a user select one or few users, then we creat a chat in
DB with a list of members, then whenever they send a new message in that
chat, then we publish to all menbers via their private channel. Each user
has their unique private channel. What do you think?
